This standard utilizes the Published, ertified Data, of performance standard ISO/AHI/ANSI/ASHAE :1998, and includes the definitions; rating requirements; minimum data requirements for Published atings; marking and nameplate data; and conformance conditions required. OP All Versatec ompact Series product is safety listed under UL1995 thru ETL and performance listed with AHI in accordance with standard

6 AHI Data cont. The performance standard AHI/ASHAE/ISO became effective January 1, 2000 and replaces AHI Standards 320, 325, and 330. This new standard has three major categories: Water Loop (comparable to AI 320), round Water (AI 325), and round Loop (AI 330). Although these standards are similar there are some differences: Unit of Measure: The ooling OP The cooling efficiency is measured in EE (US version measured in Btu/h per Watt. The Metric version is measured in a cooling OP (Watt per Watt) similar to the traditional OP measurement. Water onditions Differences Entering water temperatures have changed to reflect the centigrade temperature scale. For instance the water loop heating test is performed with 68 F (20 ) water rounded down from the old 70 F (21.1 ). Air onditions Differences Entering air temperatures have also changed (rounded down) to reflect the centigrade temperature scale. For instance the cooling tests are performed with 80.6 F (27 ) dry bulb and 66.2 F (19 ) wet bulb entering air instead of the traditional 80 F (26.7 ) DB and 67 F (19.4 ) WB entering air temperatures. 80.6/66.2 data may be converted to 80/67 using the entering air correction table. This represents a significantly lower relative humidity than the old 80/67 of 50% and will result in lower latent capacities. Pump Power orrection alculation Within each model, only one water flow rate is specified for all three groups and pumping Watts are calculated using the following formula. This additional power is added onto the existing power consumption. Pump power correction = (gpm x ) x (Press Drop x 2990) / 300 Where gpm is waterflow in gpm and Press Drop is the pressure drop through the unit heat exchanger at rated water flow in feet of head. Blower Power orrection alculation Blower power is corrected to zero external static pressure using the following equation. The nominal airflow is rated at a specific external static pressure. This effectively reduces the power consumption of the unit and increases cooling capacity but decreases heating capacity. These Watts are significant enough in most cases to increase EE and OPs fairly dramatically over AI 320, 325, and 330 ratings. Blower Power orrection = (cfm x 0.472) x (esp x 249) / 300 Where cfm is airflow in cfm and esp is the external static pressure at rated airflow in inches of water gauge. ISO apacity and Efficiency alculations The following equations illustrate cooling calculations: ISO ooling apacity = ooling apacity (Btu/h) + (Blower Power orrection (Watts) x 3.412) ISO EE Efficiency (W/W) = ISO ooling apacity (Btu/h) x / [Power Input (Watts) - Blower Power orrection (Watts) + Pump Power orrection (Watt)] The following equations illustrate heating calculations: ISO Heating apacity = Heating apacity (Btu/h) - (Blower Power orrection (Watts) x 3.412) ISO OP Efficiency (W/W) = ISO Heating apacity (Btu/h) x / [Power Input (Watts) - Blower Power orrection (Watts) + Pump Power orrection (Watt)] omparison of Test onditions AI 320 ISO/AHI WLHP AI 325 ISO/AHI WHP AI 330 onversions: Airflow (lps) = cfm x 0.472; Water Flow (lps) = gpm x ; esp (Pascals) = esp (in wg) x 249; Press Drop (Pascals) = Press Drop (ft hd) x 2990 ISO/AHI LHP ooling Entering Air - DB/WB F 80/ / / / / /66.2 Entering Water - F / Fluid Flow ate * ** ** ** ** ** Heating Entering Air - DB/WB F Entering Water - F / Fluid Flow ate * ** ** ** ** ** Note *: Flow rate is set by 10 F rise in standard cooling test Note **: Flow rate is specified by the manufacturer Part load entering water conditions not shown.

7 The Versatec ompact Series The Versatec ompact is the latest in WaterFurnace s efforts to be the best in the water source heat pump industry. The Versatec ompact raises the bar for boiler/tower applications by providing flexibility and efficiency into a compact cabinet at a competitive price. A compact cabinet is important when choosing a replacement heat pump. Many water source heat pumps of the s were relatively low efficiency models with a small footprint. Once they are installed in a building and piping and ductwork is piped around the unit replacement with a larger footprint is nearly impossible. The Versatec ompact combines the high efficiency of 21 st century product in a footprint that matches a 1980 heat pump for easy replacement. The chart below shows a comparison of a typical 1980 legacy wshp and current competitor data versus the Versatec ompact Series.

High Efficiency The Versatec ompact Series is a high efficiency water source heat pump in a compact vertical and horizontal cabinet. The product features highly efficient and reliable single capacity rotary/scroll compressors mated with large blowers. These blowers are driven by efficient 3 speed PS blower motors, 5-speed EM blower motors, or highly efficient variable speed EM blower motors. Super Quiet Option An optional Super Quiet Sound Package is also available for a modest cost and features multi-density laminate lined compressor blanket designed to completely surround the compressor and suppress low frequency noise. Indoor Air Quality (IAQ) All Versatec ompact Series features several IAQ benefits: orrosion-free composite double-sloped drain pan to eliminate standing water and prevent bacterial growth A washable surface on insulation in all air handler compartments to allow cleanability and inhibit bacteria growth. Optional non-fibrous closed cell insulation is also available for more sensitive applications by special request through commercial sales.. Open filter rail comes standard for non-ducted return applications. Filter rail is field switchable from 1 in. to 2 in. [2.54 to 5.1 cm] for more filter options. Optional factory mounted, four sided, deluxe filter rack that is field switchable from 1 in. to 2 in. [2.54 to 5.1 cm] is available for ducted return applications. Standard supplied filter is a pleated MEV 4, 1 in. [2.54 cm]. An optional low static high efficiency 2 in. [5.1 cm] MEV 13, for LEED certification points, is also available. Internally Mounted Solenoid Valve Option When variable speed circulating pump systems are designed, low pressure drop (high v) solenoid valves are specified at each unit to vary the pump according to flow required. It is important that these valves be low pressure drop to avoid unwanted pump watts. This option factory installs this valve inside the unit. Secondary Drain onnection Option Some local building authority s interpretation of codes require more condensate overflow protection than standard microprocessor based condensate sensors offer. In these areas a full secondary drain pan might be required causing both increased cost and unit service access issues. In many of these cases a secondary drain connection option can be added to the unit to pass this local interpretation of condensate drain redundancy. This option adds a second PV drain connection to the drain pan at a higher level. Phase uard Monitor Factory mounted phase guard device is available to protect the compressor against loss of phase. 10

11 The Versatec ompact Series cont. Aurora Base ontrol The Aurora Base ontrol (AB) System is a complete residential and commercial comfort system that brings all aspects of the HVA system into one cohesive module network. Aurora uses the Modbus communication protocol to communicate between modules. Each module contains the logic to control all features that are connected to the module. The Aurora Base ontrol (AB) has two Modbus channels. The first channel is configured as a master for connecting to devices such as a communicating thermostat, expansion board, or other slave devices. The second channel is configured as a slave for connecting the Aurora Interface Diagnostic (AID) Tool. Aurora Unitary Protocol onverter (UP) The optional Aurora UP control provides unparalleled capability in several areas including energy, refrigerant, and performance monitoring, humidity, energy management, and service diagnostics, and then communicates it all thru standard DD protocols like N2, Lon and BAnet MS/TP. The most unique feature is integration of the Aurora Base ontrol and UP into the Versatec ompact as an integrated heat Pump and DD controller providing both a cost advantage and providing features not typically found on WSHP controls. This integration allows heat pump monitoring sensors, status and service diagnosis faults to be communicated thru the DD direct to the building automation system (BAS), giving building supervisors detailed and accurate information on every piece of equipment without removing an access panel! ontrol eneral Description Application Display/Interface Protocol Aurora Base ontrol The AB microprocessor provides all the features necessary to operate today s standard WSHPs that utilize dual capacity compressors and variable speed EM/5 speed EM blower motors with hot gas reheat. This control can communicate to a handheld diagnostic tool to help the installing contractor or service technician with equipment setup and service. By utilizing Modbus TU communication protocol, the AB board can communicate with additional devices on the Aurora network Used for residential and commercial applications that use single or dual capacity compressors with PS, 5-speed EM, or variable speed EM blower motors. This base control can also communicate to the AID Tool to display faults, inputs/outputs, and software revision. ommercial features such as hot gas reheat, slow opening water valve, and random start are also capable with the AB board. Optional AID toll can be used for field service. Standalone Aurora Base ontrol w/up BAnet or N2 The Aurora Unitary Protocol onverter (UP) is an integrated solution and communicates directly with the Aurora Heat Pump ontrols and allows access/control of a variety of internal Aurora heat pump operations such as sensors, relay operation, faults and other information. In turn, the UP then converts internal Aurora Modbus protocol to BAnet MS/TP, or N2 protocols and communicates to the BAS system. This provides the great benefit of complete control integration and a myriad of information available to the BAS from the heat pump control. Plus it also allows individual unit configuration such as EM fan speeds or freeze protection setting directly over the BAS without the need for access to the actual heat pump. The Aurora UP is implemented with the Aurora Base ontroller (AB) heat pump control into our latest water source heat pumps. All Internal Aurora points are accessible to the UP via firmware providing an integrated solution. All zone temperatures and zone sensors are connected to the UP on an Net bus, simplifying hook up at the unit. Net sensors can include a combination of zone temperature and humidity, O2, and VO sensors. The UP includes built-in support for a custom configurable keypad/display unit. Optional Equipment Touch display BAnet MS/ TP or N2 Open (DIP selectable) Aurora Base ontrol w/up LonWorks The Aurora Unitary Protocol onverter (UP) is an integrated solution and communicates directly with the Aurora Heat Pump ontrols and allows access/control of a variety of internal Aurora heat pump operations such as sensors, relay operation, faults and other information. In turn, the UP then converts internal Aurora Modbus protocol to LONWorks protocol and communicates to the BAS system. The Aurora UP is implemented with the Aurora Base ontroller (AB) heat pump control into our latest water source heat pumps. All Internal Aurora points are accessible to the UP via firmware providing an integrated solution. All zone temperatures and zone sensors are connected to the UP on an Net bus, simplifying hook up at the unit.

Variable Speed EM Blower Speeds The blower speeds can be changed either by using the EM manual configurations mode method or by using the Aurora AID Tool directly (see Instruction uide: Aurora Interface and Diagnostics (AID) Tool topic). Field Selectable Options via Software (Selectable via the Aurora AID Tool) EM Blower Speeds An EM blower motor can be driven directly using the onboard PWM output. Four blower speeds are available, based upon the, Y1 (low), Y2 (high), and Aux input signals to the board. The blower speeds can be changed either by the EM manual configurations mode method (see EM onfiguration Mode topic) or by using the Aurora AID Tool directly. All four blower speeds can be set to the same speed if desired. Aux blower speed will remain at default or current setting and requires the AID Tool for adjustment. Safety Features The following safety features are provided to protect the compressor, heat exchangers, wiring and other components from damage caused by operation outside of design conditions. Fuse a 3 amp automotive type plug-in fuse provides protection against short circuit or overload conditions. Anti-Short ycle Protection 4 minute anti-short cycle protection for the compressor. andom Start 5 to 80 second random start upon power up. Fault etry in the fault condition, the control will stage off the outputs and then try again to satisfy the thermostat Y input call. Once the thermostat input calls are satisfied, the control will continue on as if no fault occurred. If 3 consecutive faults occur without satisfying the thermostat Y input call, then the control will go to Lockout mode. Lockout when locked out, the blower will operate continuously in speed, and PS blower motor output will remain on. The Alarm output (ALM) and Lockout output (L) will be turned on. The fault type identification display LED1 (ed) shall flash the fault code. To reset lockout conditions with SW2-8 On, thermostat inputs Y1, Y2, and W must be removed for at least 3 seconds. To reset lockout conditions with SW2-8 Off, thermostat inputs Y1, Y2, W, and DH must be removed for at least 3 seconds. Lockout may also be reset by turning power off for at least 30 seconds or by enabling the emergency shutdown input for at least 3 seconds. Lockout With Emergency Heat - if the control is locked out in the heating mode, and a Y2 or W input is received, the control will operate in the emergency heat mode while the compressor is locked out. The first emergency heat output will be energized 10 seconds after the W input is received, and the blower will shift to high speed. If the control remains locked out, and the W input is present, additional stage of emergency heat will stage on after 2 minutes. When the W input is removed, all of the emergency heat outputs will turn off, and the EM blower will shift to speed and PS blower motor output will remain on. High Pressure fault is recognized when the Normally losed High Pressure Switch, P4-9/10 opens, no matter how momentarily. The High Pressure Switch is electrically in series with the ompressor ontactor and serves as a hardwired limit switch if an overpressure condition should occur. Low Pressure - fault is recognized when the Normally losed Low Pressure Switch, P4-7/8 is continuously open for 30 seconds. losure of the LPS any time during the 30 second recognition time restarts the 30 second continuous open requirement. A continuously open LPS shall not be recognized during the 2 minute startup bypass time. Loss of harge fault is recognized when the Normally losed Low Pressure Switch, P4-7/8 is open prior to the compressor starting. ondensate Overflow - fault is recognized when the impedance between this line and 24 VA common or chassis ground drops below 100K ohms for 30 seconds continuously. Freeze Detection (oax) - set points shall be either 30 F or 15 F. When the thermistor temperature drops below the selected set point, the control shall begin counting down the 30 seconds delay. If the thermistor value rises above the selected set point, then the count should reset. The resistance value must remain below the selected set point for the entire length of the appropriate delay to be recognized as a fault. This fault will be ignored for the initial 2 minutes of the compressor run time. Freeze Detection (Air oil) - uses the FP2 input to protect against ice formation on the air coil. The FP2 input will operate exactly like FP1 except that the set point is 30 degrees and is not field adjustable. 17

18 ontrols - Aurora Base ontrol cont. Over/Under Voltage Shutdown - An over/under voltage condition exists when the control voltage is outside the range of 18 VA to 30 VA. If the over/under voltage shutdown lasts for 15 minutes, the lockout and alarm relay will be energized. Over/under voltage shutdown is selfresetting in that if the voltage comes back within range of 18 VA to 30 VA for at least 0.5 seconds, then normal operation is restored. Operation Description Power Up - The unit will not operate until all the inputs and safety controls are checked for normal conditions. The unit has a 5 to 80 second random start delay at power up. Then the compressor has a 4 minute anti-short cycle delay after the random start delay. Standby In standby mode, Y1, Y2, W, DH, and are not active. Input O may be active. The blower and compressor will be off. Heating Operation Single ompressor Heating, 2nd Stage (Y1, Y2) The compressor will be staged to full capacity 20 seconds after Y2 input is received. The EM blower will shift to high speed seconds after the Y2 input is received. Dual ompressor Heating, 2nd Stage (Y1, Y2) In dual compressor operation, two AB boards used in 24 VA operation, there will be a Y2 call to the Y1 input on the second AB. The compressor will stage to full capacity 30 seconds after Y1 input is received to the second board. Single ompressor Heating, 3rd Stage (Y1, Y2, W) The hot water pump is de-energized and the first stage of electric heat is energized 10 seconds after the W command is received. If the demand continues the second stage of electric heat will be energized after 5 minutes. Dual ompressor Heating, 3rd Stage (Y1, Y2, W) - The first stage of electric heat is energized 10 seconds after the W command is received. If the demand continues the second stage of electric heat will be energized after 5 minutes Emergency Heat (W) - The blower will be started on speed, 10 seconds later the first stage of electric heat will be turned on. 5 seconds after the first stage of electric heat is energized the blower will shift to Aux speed. If the emergency heat demand is not satisfied after 2 minutes the second electric heat stage will be energized. ooling Operation In all cooling operations, the reversing valve directly tracks the O input. Thus, anytime the O input is present, the reversing valve will be energized. Single ompressor ooling, 2nd Stage (Y1, Y2, 0) The compressor will be staged to full capacity 20 seconds after Y2 input was received. The EM blower will shift to high speed 15 seconds after the Y2 input was received. Dual ompressor ooling, 2nd Stage (Y1, Y2, O) In dual compressor operation, two AB boards used in 24 VA operation, there will be a Y2 call to the Y1 input on the second AB. The compressor will stage to full capacity 30 seconds after Y1 input is received to the second board. Blower () - The blower will start immediately upon receiving a thermostat command. If there are no other commands from the thermostat the EM will run on speed until the command is removed. egardless of blower input () from the thermostat, the blower will remain on for 30 seconds at the end of each heating, cooling, and emergency heat cycle. Dehumidification (Y1, O, DH or Y1, Y2, O, DH) - When a DH command is received from the thermostat during a compressor call for cooling the EM blower speed will be reduced by 15% to increase dehumidification. Emergency Shutdown - Four (4) seconds after a valid ES input, P2-7 is present, all control outputs will be turned off and remain off until the emergency shutdown input is no longer present. The first time that the compressor is started after the control exits the emergency shutdown mode, there will be an anti-short cycle delay followed by a random start delay. Input must be tied to common to activate. ontinuous Blower Operation - The blower output will be energized any time the control has a input present, unless the control has an emergency shutdown input present. The blower output will be turned off when input is removed. Load Shed - The LS input disables all outputs with the exception of the blower output. When the LS input has been cleared, the anti-short cycle timer and random start timer will be initiated. Input must be tied to common to activate. Blower () - The blower will start immediately upon receiving a thermostat command. If there are no other commands from the thermostat the EM will run on speed until the command is removed. egardless of blower input () from the thermostat, the blower will remain on for 30 seconds at the end of each heating cycle. 18

20 ontrols - UP DD ontrol (optional) Aurora UP ontroller ZS Series Sensors The Aurora Unitary Protocol onverter (UP) is designed to add-on to any Aurora based heat pump control. The Aurora Unitary Protocol onvertor (UP) is designed to allow water source heat pumps to be integrated into Building Automation Systems (BAS) with ease. The Aurora UP is an integrated solution and communicates directly with the Aurora Heat Pump ontrols and allows access/control of a variety of internal Aurora heat pump operations such as sensors, relay operation, faults and other information. In turn, the UP then converts internal Aurora Modbus protocol to BAnet MS/TP, LON, or N2 protocols and communicates to the BAS system. This provides the great benefit of complete control integration and a myriad of information available to the BAS from the heat pump control. Plus it also allows individual unit configuration such as EM fan speeds or freeze protection setting directly over the BAS without the need for access to the actual heat pump. The Aurora UP is programmed using the powerful Eikon object oriented. The Aurora UP is implemented with the Aurora Base ontroller (AB) heat pump control into our latest water source heat pumps. This will allow for a BAS to integrate and communicate to the heat pump thru a choice of 3 different communication protocols. The Aurora UP has the ability to communicate BAnet MS/TP, N2 open, or LonWorks (requires LON Plugin card). This flexibility is possible due to the onboard dipswitches which allow for the desired protocol and baud rate to be selected in the field. All zone temperatures and zone sensors are connected to the UP on an Net bus, simplifying hook up at the unit. Net sensors can include a combination of zone temperature and humidity, O2, and VO sensors. The UP includes built-in support for a custom configurable keypad/display unit - BAview6 (4-line by 40 character per line display) or BAview5 (2-line by 16 character per line display). Up to 2 Keypad/display units can be mounted remotely for configuration and troubleshooting. There are an extensive number of points that the UP has available over the network for integration into the BAS. ontrol programmers need to carefully determine which points they want to add into the BAS database. A list of the BAnet points, N2 points, and LON SNVTs are available along with their individual point descriptions by contacting the ommercial Solutions roup at

27 ontrols - UP DD ontrol (optional) cont. ZS Series Net Sensor Overview The ZS Series line of intelligent zone sensors provides the function and flexibility you need to manage the conditions important to the comfort and productivity of the zone occupants. The ZS sensors are available in a variety of zone sensing combinations to address your application needs. These combinations include temperature, relative humidity, and indoor air quality (carbon dioxide or VOs (Volatile Organic ompounds)). They are built to be flexible allowing for easy customization of what the user/ technician sees. Designed to work with the Aurora UP controllers the ZS sensor line includes the ZS Base, ZS Plus, ZS Pro and ZS Pro-F. The UP uses a proprietary communication called net to receive the space temperature from the zone sensor. This is done using (2) 18 AW twisted pair unshielded cables for a total of 4 wires connected to the net port. The sensor gets its power from the UP controller and connecting multiple sensors to one UP will allow for space temperature averaging. The UP can support one ZS Pro or ZS Pro F with up to four ZS standard sensors wired to the net port on the UP for a total of 5 zone sensors. The sensors use a precise 10k ohm thermistor with less than 0.18 F drift over a ten year span, this allows for less maintenance or re-calibration after installation. The sensors also have a hidden communication port for connecting a BAview or local laptop that provides access to the equipment for commissioning and maintenance. The table below shows the features of each of the four sensors that are currently available.

29 Application Notes The losed Loop Heat Pump oncept The basic principle of a water source heat pump is the transfer of heat into water from the space during cooling, or the transfer of heat from water into the space during heating. Extremely high levels of energy efficiency are achieved as electricity is used only to move heat, not to produce it. Using a typical WaterFurnace Versatec ompact Series, one unit of electricity will move four to five units of heat. When multiple water source heat pumps are combined on a common circulating loop, the ultimate in energy efficiency is created: The WaterFurnace units on cooling mode are adding heat to the loop which the units in heating mode can absorb, thus removing heat from the area where cooling is needed, recovering and redistributing that heat for possible utilization elsewhere in the system. In modern commercial structures, this characteristic of heat recovery from core area heat generated by lighting, office equipment, computers, solar radiation, people or other sources, is an important factor in the high efficiency and low operating costs of WaterFurnace closed source heat pump systems. eturn Water low because units can be added to the loop on an as needed basis - perfect for speculative buildings. Installed costs are low since units are self-contained and can be located adjacent to the occupied space, requiring minimal ductwork. Maintenance can be done on individual units without system shut-down. onditions remain comfortable since each unit operates separately, allowing cooling in one area and heating in another. Tenant spaces can be finished and added as needed. Power billing to tenants is also convenient since each unit can be individually metered: each pays for what each uses. Nighttime and/or weekend uses of certain areas are possible without heating or cooling the entire facility. A decentralized system also means if one unit should fault, the rest of the system will continue to operate normally, as well as eliminating air cross-contamination problems and expensive high pressure duct systems requiring an inefficient electric resistance reheat mode. The Versatec ompact Approach There are a number of proven choices in the type of Versatec ompact Series system which would be best for any given application. Most often considered are: Vertical - losed Loop/round Source Versatec Unit Versatec Unit Heater/ ejector Versatec Unit Versatec Unit Versatec Unit Versatec Unit Pumps Supply Water In the event that a building's net heating and cooling requirements create loop temperature extremes, Versatec ompact Series units have the extended range capacity and versatility to maintain a comfortable environment for all building areas. Excess heat can be stored for later utilization or be added or removed in one of three ways; by ground-source heat exchanger loops: plate heat exchangers connected to other water sources, or conventional cooler/ boiler configurations. Your WaterFurnace representative has the expertise and computer software to assist in determining optimum system type for specific applications. The losed Loop Advantage A properly applied water source heat pump system offers many advantages over other systems. First costs are losed Loop/round-Source Systems utilize the stable temperatures of the earth to maintain proper water source temperatures (via vertical or horizontal closed loop heat exchangers) for Versatec ompact Series extended range heat pump system. Sizes range from a single unit through many hundreds of units. When net cooling requirements cause closed loop water temperatures to rise, heat is dissipated into the cooler earth through buried high strength plastic pipe heat exchangers. onversely if net space heating demands cause loop heat absorption beyond that heat recovered from building core areas, the loop temperature will fall causing heat to be extracted from the earth. Due to the extended loop temperatures, AHI/ ISO round Loop Heat Pumps are required for this application. Because auxiliary equipment such as a fossil 29

30 Application Notes cont. fuel boiler and cooling tower are not required to maintain the loop temperature, operating and maintenance costs are very low. Plate Heat Exchanger - losed Loop/round Water round-source systems are most applicable in residential and light commercial buildings where both heating and cooling are desired, and on larger envelope dominated structures where core heat recovery will not meet overall heating loads. Both vertical and horizontally installed closed-loops can be used. The land space required for the heat exchangers is sq. ft./ton on vertical (drilled) installations and sq. ft./ton for horizontal (trenched) installations. losed loop heat exchangers can be located under parking areas or even under the building itself. On large multi-unit systems, sizing the closed loop heat exchanger to meet only the net heating loads and assisting cooling loads with a closed circuit cooling tower may be the most cost effective choice. Surface Water - losed Loop/round Source losed Loop/round Water Plate Heat Exchanger Systems utilize lake, ocean, well water or other water sources to maintain closed loop water temperatures in multi-unit Versatec ompact systems. A plate frame heal exchanger isolates the units from any contaminating effects of the water source, and allows periodic cleaning of the heat exchanger during off peak hours. Operation and benefits are similar to those for groundsource systems. Due to the extended loop temperatures, AHI/ISO round Loop Heat Pumps are required for this application. losed loop plate heat exchanger systems are applicable in commercial, marine, or industrial structures where the many benefits of a water source heat pump system are desired, regardless of whether the load is heating or cooling dominated. losed Loop/round-Source Surface Water Systems also utilize the stable temperatures of Surface Water to maintain proper water source temperatures for Versatec ompact Series extended range heat pump systems. These systems have all of the advantages of horizontal and vertical closed loop systems. Due to the extended loop temperatures, AHI/ISO round Water or round Loop Heat Pumps are required for this application. In cooling dominated structures, the ground-source surface water systems can be very cost effective especially where local building codes require water retention ponds for short term storage of surface run-off. Sizing requirements for the surface water is a minimum of 500 sq. ft./ton of surface area at a minimum depth of 8 feet. WaterFurnace should be contacted when designs for heating dominated structures are required. 30

31 Application Notes cont. ooler/boiler - losed Loop losed Loop /ooler-boiler Systems utilize a closed heat recovering loop with multiple water source heat pumps in the more conventional manner. Typically a boiler is employed to maintain closed loop temperatures above 60 F and a cooling tower to maintain loop temperatures below 90 F. These systems are applicable in medium to large buildings regardless of whether the load is heating or cooling dominated. Due to the moderate loop temperatures, AHI/ISO Water Loop Heat Pumps are required for this application. 31

32 Water Quality It is the responsibility of the system designer and installing contractor to ensure that acceptable water quality is present and that all applicable codes have been met in these installations. Failure to adhere to the guidelines in the water quality table could result in loss of warranty. In ground water situations where scaling could be heavy or where biological growth such as iron bacteria will be present, a closed loop system is recommended. The heat exchanger coils in ground water systems may, over a period of time, lose heat exchange capabilities due to a buildup of mineral deposits inside. These can be cleaned, but only by a qualified service mechanic, as special solutions and pumping equipment are required. Hot water generator coils can likewise become scaled and possibly plugged. In areas with extremely hard water, the owner should be informed that the heat exchanger may require occasional flushing. Units with cupronickel heat exchangers are recommended for open loop applications due to the increased resistance to build-up and corrosion, along with reduced wear caused by acid cleaning. Failure to adhere to the guidelines in the water quality table could result in the loss of warranty. Water Treatment Do not use untreated or improperly treated water. Equipment damage may occur. The use of improperly treated or untreated water in this equipment may result in scaling, erosion, corrosion, algae or slime. Purchase of a pre-mix antifreeze could significantly improve system reliability if the water quality is controlled and there are additives in the mixture to inhibit corrosion. There are many examples of such fluids on the market today such as Environol 1000 (pre-mix ethanol), and others. The services of a qualified water treatment specialist should be engaged to determine what treatment, if any, is required. The product warranty specifically excludes liability for corrosion, erosion or deterioration of equipment. The heat exchangers and water lines in the units are copper or cupronickel tube. There may be other materials in the buildings piping system that the designer may need to take into consideration when deciding the parameters of the water quality. If antifreeze or water treatment solution is to be used, the designer should confirm it does not have a detrimental effect on the materials in the system. ontaminated Water In applications where the water quality cannot be held to prescribed limits, the use of a secondary or intermediate heat exchanger is recommended to separate the unit from the contaminated water. The table above outlines the water quality guidelines for unit heat exchangers. If these conditions are exceeded, a secondary heat exchanger is required. Failure to supply a secondary heat exchanger where needed will result in a warranty exclusion for primary heat exchanger corrosion or failure.

33 Installation Notes Typical Unit Installation Unit Location Locate the unit in an indoor area that allows for easy removal of the filter and access panels. Location should have enough space for service personnel to perform maintenance or repair. Provide sufficient room to make water, electrical and duct connection(s). If the unit is located in a confined space, such as a closet, provisions must be made for return air to freely enter the space by means of a louvered door, etc. Any access panel screws that would be difficult to remove after the unit is installed should be removed prior to setting the unit. On horizontal units, allow adequate room below the unit for a condensate drain trap and do not locate the unit above supply piping. are should be taken when units are located in unconditioned spaces to prevent damage from frozen water lines and excessive heat that could damage electrical components. Water Piping Piping is usually design as reverse return to equalize flow paths through each unit. A short flexible pressure rated hose is used to make connection to the fixed building piping system. This hose is typically stainless steel braid and includes a swivel fitting on one end for easy removal and is flexible to help isolate the unit for quieter operation. Isolation valves for servicing, y-strainers for filtering and memory-stop flow valve or a balancing valve can be provided for consistent water flow through the unit. All unit source water connections are fittings that accept a male pipe thread (MPT). Insert the connectors by hand, then tighten the fitting with a wrench to provide a leakproof joint. The open and closed loop piping system should include pressure/temperature ports for serviceability. The proper water flow must be provided to each unit whenever the unit operates. To assure proper flow, use pressure/ temperature ports to determine the flow rate. These ports should be located at the supply and return water connections on the unit. The proper flow rate cannot be accurately set without measuring the water pressure drop through the refrigerant-to-water heat exchanger. Never use flexible hoses smaller than the inside diameter of the water connection at the unit. Limit hose length to 10 feet per connection. heck carefully for water leaks. 33

34 Installation Notes cont. Installing Horizontal Units emove and discard the compressor hold down shipping bolt or screw located at the front or side (side, horizontal only) of the compressor mounting bracket prior to setting the unit in place. Horizontal units are available with side or end discharge. NOTE: Left (ight) eturn Side Discharge cannot be converted to Left (ight) eturn End Discharge or vice versa, without additional custom sheet metal parts. Horizontal units are normally suspended from a ceiling by four 3/8 in. diameter threaded rods. The rods are usually attached to the unit by hanger bracket kits furnished with each unit. Lay out the threaded rods per the Hanger Bracket Dimensions table. Assemble the hangers to the unit as shown. Securely tighten the brackets to the unit using the weld nuts located on the underside of the bottom panel. When attaching the hanger rods to the bracket, a double nut is required since vibration could loosen a single nut. To allow filter access, install hanger brackets as illustrated in the Hanger Bracket Locations section. The unit should be pitched approximately 1/4 in. towards the drain in both directions to facilitate the removal of condensate. Use only the bolts provided in the kit to attach hanger brackets. The use of longer bolts could damage internal parts. Some applications require the installation of horizontal units on an attic floor. In this case, the unit should be set in a full size secondary drain pan on top of a vibration absorbing pad. The secondary drain pan prevents possible condensate overflow or water leakage damage to the ceiling. The secondary drain pan is usually placed on a plywood base isolated from the ceiling joists by additional layers of vibration absorbing material. AUTION: Do not use rods smaller than 3/8 in. diameter since they may not be strong enough to support the unit. The rods must be securely anchored to the ceiling. 34

35 Installation Notes cont. Acoustical onsiderations and Equipment Sound Performance Sound Performance The Versatec ompact Series is third party sound rated in accordance with AI 260. Please consult WaterFurnace Sound Performance Data atalog for details on the AHI standard and sound performance data. ecommendations for Noise eduction Horizontal Unit Location Specify equipment with quietest sound power ratings Do not locate units above areas with a required N 40 or less Space WSHP at least 10 ft (3m) apart to avoid noise summing of multiple units in a space. Maximize the height of the unit above the ceiling (horizontal). Suspend unit with isolation grommets that are appropriately rated to reduce vibrations (horizontal). Vertical Unit Location Specify equipment with quietest sound power ratings Space WSHP at least 10 ft (3m) apart to avoid noise summing of multiple units in a space. Acoustic ceiling coatings can greatly reduce noise levels in mechanical rooms. Mount unit on a sound absorbing pad, extruded polystyrene, rubber or cork pad. Ductwork Ensure return air grilles will not allow line of site noise to transfer to adjacent space. Use a sound barrier or some other material to isolate the grille from the unit. A supply grille, boot and short piece of flex duct pointed away from the unit can greatly attenuate equipment noise. Use a canvas isolation duct connector at the supply and return duct connection of the unit. Internally line the discharge and return duct within the first 4-8 feet of unit with acoustic insulation. Install an internally lined L shaped return duct elbow at return grille. Face the elbow away from adjacent units. Always install at least one 90 elbow in the discharge duct to eliminate line of sight noise transmission of the blower. Use turning vanes at all elbows and tees to reduce turbulence. Limit supply duct velocities to less than 1,000 fpm Design and install ductwork as stiff as possible Allow 3 duct diameters both up and down stream of the unit before any fittings or transitions are installed. Use duct sealant on all duct joints. Install a short (2-4 ) of flex duct on all branch ducts just prior to discharge boot or diffuser to reduce vibration and duct sound prior to delivery in the room. Locate the branch duct balancing damper as far away from the diffuser as possible. In ceiling plenum systems, install an internally lined L shaped return duct elbow at unit. Face the elbow away from adjacent units (horizontal). 35

50 Selection Example To achieve optimal performance, proper selection of each heat pump is essential. A building load program should be used to determine the heating and cooling load of each zone. A computer software selection program can then be used to develop an accurate and complete heat pump schedule. Software can be obtained from your local WaterFurnace representative. While a computer software program is the easiest and most accurate method to size and select equipment, however, selection can still be accomplished manually using this manual and the following selection procedure. Sizing so that the actual sensible capacity of the equipment will satisfy the sensible capacity of the zone is the recommended method for best results. Boiler/Tower Application Typical boiler/tower application will result in entering water temperatures of F with 70 F for heating and 90 F for cooling. Water to refrigerant insulation option would not be required. Flow rates are 2.5 to 3 gpm per ton with 2.5 gpm per ton often representing an economical design point. eothermal Application Typical geothermal application can result in a wide entering water temperature range of F. Typically minimum heating entering water temperatures can range from 30 to 50 F depending upon loop type and geographical location. ooling performance should be calculated using a maximum loop temperature of 100 F in most loop applications. Water flow is typically 2.5 to 3 gpm per ton with 3 gpm per ton recommended with the more extreme loop temperatures. PLEASE NOTE THAT WATE OIL INSULATION OPTION SHOULD BE SELETED WHEN ENTEIN WATE TEMPEATUES AE EXPETED TO BE BELOW F. eothermal Selection Example Step 1: Determine the actual heating and cooling loads at the desired dry bulb and wet bulb conditions. Step 2: Obtain the following design parameters: Entering water temperature, water flow rate in gpm, airflow in cfm, water flow pressure drop and design wet and dry bulb temperatures. Airflow, cfm, should be between 300 and 450 cfm per ton. Unit water pressure drop should be kept as close as possible to each other to make water balancing easier. o to the appropriate tables and find the proper indicated water flow and water temperature. Step 4: Enter tables at the design water flow and water temperature. ead the total and sensible cooling capacities (NOTE: interpolation is permissible, extrapolation is not). Step 5: ead the heating capacity. If it exceeds the design criteria it is acceptable. It is quite normal for water source heat pumps to be selected on cooling capacity only since the heating output is usually greater than the cooling capacity. Step 6: Determine the correction factors associated with the variable factors of dry bulb and wet bulb. orrected Total ooling = tabulated total cooling x wet bulb correction. orrected Sensible ooling = tabulated sensible cooling x wet/dry bulb correction. Step 7: ompare the corrected capacities to the load requirements. Normally if the capacities are within 10% of the loads, the equipment is acceptable. It is better to undersize than oversize, as undersizing improves humidity control, reduces sound levels and extends the life of the equipment. Step 8: When complete, calculate water temperature rise and assess the selection. If the units selected are not within 10% of the load calculations, then review what effect changing the gpm, water temperature and/or airflow and air temperature would have on the corrected capacities. If the desired capacity cannot be achieved, select the next larger or smaller unit and repeat the procedure. emember, when in doubt, undersize slightly for best performance. Example Equipment Selection - ooling 1. Load Determination: Assume we have determined that the appropriate cooling load at the desired dry bulb 80 F and wet bulb 65 F conditions is as follows: Total ooling...51,500 Btu/h Sensible ooling...34,300 Btu/h Entering Air Temp...75 F Dry Bulb / 65 F Wet Bulb 2. Design onditions: Similarly, we have also obtained the following design parameters: Entering Water Temp F Water Flow (Based upon 10 F rise in temp.) 15.0 gpm Airflow equired... 1, in. wg. Step 3: Select a unit based on total and sensible cooling conditions. Select a unit which is closest to, but no larger than, the actual cooling load. 50

51 Selection Example cont. 3, 4 & 5. HP Selection: After making our preliminary selection (UB*060 variable speed EM), we enter the tables at design water flow and water temperature and read Total ooling, Sens. ooling and Heat of ej. capacities: Total ooling...54,100 Btu/h Sensible ooling... 40,500 Btu/h Heat of ejection...68,800 Btu/h 6 & 7. Entering Air and Airflow orrections: Next, we determine our correction factors. (efer to orrection Factor Tables - Airflow and Entering Air correction tables using 1750 cfm. or 1,750 2,000 nom. = 87.5%). orrected Total ooling = 54,100 x x = 51,373 orrected Sens ooling = 40,500 x x = 33,147 orrected Heat of eject = 68,800 x x = 65,402 H = 500 x gpm x (T in - T out ) H = (T in - T out ) or T ise 500 x gpm 65, x 15 = 8.72 F ise 8. Water Temperature ise alculation & Assessment: NOTE: 500 = parameters for water & 485 = parameters for antifreeze solutions to 30% weight. When we compare the orrected Total ooling and orrected Sensible ooling figures with our load requirements stated in Step 1, we discover that our selection is within +10% of our sensible load requirement. Further more, we see that our orrected Total ooling figure is within 1,000 Btu/h of the actual indicated load. Antifreeze orrections atalog performance can be corrected for antifreeze use. Please use the following table and note the example given. Antifreeze Type Antifreeze % by wt ooling apacity Heating apacity Pressure Drop EWT - degf [Deg] 90 [32.2] 30 [-1.1] 30 [-1.1] Water Ethylene lycol Propylene lycol Ethanol Methanol Warning: ray area represents antifreeze concentrations greater than 35% by weight and should be avoided due to the extreme performance penalty they represent. Antifreeze orrection Example Antifreeze solution is Propylene lycol 20% by weight. Determine the corrected heating and cooling performance at 30 F and 90 F respectively as well as pressure drop at 30 F for a Versatec ompact Series UB*024-PS. The corrected cooling capacity at 90 F would be: 22,600 Btu/h x = 21,899 Btu/h The corrected heating capacity at 30 F would be: 16,800 Btu/h x = 15,338 Btu/h The corrected pressure drop at 30 F and 6 gpm would be: 20.8 ft. hd x = ft. hd. 51

Maximum of 5 sensors per UP. Maximum allowable load 210mA. See the UP install manual for possible sensor combinations. Notes 1. Use DIP Switches 5 8 to change communication protocol and DIP switches 1 2 to change BAnet baud rate DIP Switch Value ON Each ZS sensor must have a unique address, but the addresses do not need to be sequential. Use the DIP switches on the back of the ZS sensor to set an address from 0 to 4. (0 is the factory default.) Each DIP switch has the value shown in the figure to the left. Turn on as many DIP switches as you need so that their total value equals the address. Legend Factory Low Voltage Wiring Field Low Voltage Wiring J45 onnector Page 1 92
