8 Unit description E technology: Keyword Energy Efficiency Flex-Geko omfort Edition What are E motors? E-motors (= electronically commutated motors) are D motors, where the rotor is not performed as a coil, like in usual motors ( = alternating current), but consists of a permanent magnet. Electronic control of the motor enables continuous operation, where the integrated electronics ensures alternating magnetic field which adjusts itself to the relevant speed (refer to Fig. 19). In such a way the motor operates at optimal conditions, resulting in maximum torque and minimum losses. The efficiency rate of the E motors used by DencoHapppel is twice as high as the comparable motors. The application of this technology in fan coil units makes it possible to achieve high efficiency rates for fan motors - especially in part-load mode.

9 Flex-Geko omfort Edition Unit description E technology: Keyword Energy Efficiency Further aspects: ontinuous operation Low generation of heat Established and usual high motor quality Same design for 50 and 60 Hz ontinuous fan controls (MTRIX and ET.E) E fans featuring continuous operating mode offer a few of benefits: Room temperature control is performed with a higher accuracy, because occurring temperature differences can be addressed with the accordingly adjusted fan speed. This effect is assisted by using 3-point regulation valves (only with MTRIX control system). Variable fan speed control can compensate for fluctuating conditions of heating and cooling medium. Example: season-related different inlet temperature of heat generator or fluctuating volume flow rates (hydraulics) With standard fans the fan speed, which is optimal for room temperature control, must be adapted to the available fan speed stages which often leads to rapid increase of motor RPM and thus electrical power consumption. With continuous speed regulation - "hard" fan speed changes are eliminated, which provides additional acoustical comfort. The MTRIX ET.E controls uses these features by making the following functions available, the customer can select between automatic and manual operation: utomatic mode: Room temperature control with continuous regulation ( V) of a continuously variable E fan. The fan continuously operates within the minimum and maximum air volumes. Using the display control panel OP50/51 a speed limitation can be activated (mute function) in order to prevent an acoustic overshoot in automatic mode. This upper RPM limit can be separately set for each control panel (only MTRIX controls). s an additional measure to avoid possible on-site acoustical resonance occurrences, up to three speed ranges can be hidden using only MTRIX.controls and service software. Manual mode MTRIX controls: OP 50/51 (control panel with display): continuous fan setting using rotary switch between minimum and maximum air volume flow rate. OP30/31 and OP44: (speed-stage control panel): 5-speed fan setting with speed 1 = minimum air volume flow rate and speed 5 = maximum air volume flow rate. Percentage values (regarding maximum air volume flow rate) for speeds 2-4 are preconfigured by the factory (default values) and can be changed on site by others using MTRIX.P. Manual mode miniature switch ET.E: 3-stage fan control with stage 1 = min. air volume flow and stage 3 = max. air volume flow. The control voltage (Volt) of stages 1-3 are preset by others (depending on selected unit) and can be changed on-site (with DencoHappel service tool or via MODbus interface).

10 Unit description Keyword Energy Efficiency: EUROVENT Energy Label Flex-Geko omfort Edition EUROVENT Energy Label Within the framework of EU regulations (Eco-Design Directive) clear limits will be set in the future with respect to the energy efficiency of state-of-the-art technological standards. EUROVENT, as the European ssociation of Manufacturers of HV equipment, anticipates this development by having published Energy Label for fan coil units to include 5 energy efficiency classes ( to E) in January In this case the energy efficiency is composed of time-weighted relationship between cooling or heating output and consumed electrical power of the fan. If fan coil units are equipped with an energy-efficient temperature regulation system (MTRIX) the adjustment of fan speed is performed according to the situation-related heating or cooling demand. For the evaluation of energy efficiency - time percentage of the corresponding active speed stages must be considered. For the description of time-related conditions EUROVENT uses coefficient (maximum), (medium) and (minimum speed). These indicators vary, depending on heating or cooling operating mode. Fan stage oefficient Time share ooling Heating High (maximum) 5 % 5 % Medium 30 % 25 % Low (minimum) 65 % 70 % The energy efficiency relationship is composed of time-weighted shares and is presented in the example using the following formulas: ooling (FEER): Q FEER Q KHighSpeed + Q KMediumSpeed + Q = KLowSpeed Fan oil Energy Efficiency Ratio - total cooling capacity Pe HighSpeed + Pe MediumSpeed + QPe LowSpeed (= Energy efficiency relationship) Heating (FOP): FOP = Q HHighSpeed + Q HMediumSpeed + Q HLowSpeed Pe HighSpeed + Pe MediumSpeed + Pe LowSpeed Fan oil oefficient Of Performance (=Performance coefficient of fan coil unit) with Q K = Total cooling capacity with Q H = Heating capacity with Pe = Electrical power consumption of fan Higher numerical value of these indicators stands for especially outstanding energy efficiency. 10 PR G Subject to change R5-01/2017

72 Sound power level and sound pressure level Flex-Geko omfort Edition Sound pressure level d() The sound pressure specifications in the tables on pages 6-61 and Page 70/Page 71 apply to the reverberation sound field of a room with a volume of 100 m 3 and reverberation time of 0.5 s. To determine the expected sound pressure level at the installation location, refer to the - rated sound power level in conjunction with the conversion diagram in Fig.. Example: In a conference room with dimensions of (20 x 10 x 4 m) 6 assette fan coil units with model size 3 should be installed. The units are to be operated at speed 2, i.e. the sound power level amounts to 35 d(), see page 64. Determining the sound pressure level 1. ased on the room volume (800 m 3 ), an absorption surface of approx. 100 m 2 Sabin is estimated in accordance with the diagram Fig. Homes, offices, hotel rooms, conference rooms. 2. The mean distance to the fan coils is assumed to be approx. 3 m and the direction coefficient to be 4, Fig. 23. The intersection of the dotted sample lines in the diagram Fig. makes up the sound level difference: ΔL~11 d. 3. The anticipated -rated sound pressure level L P for the unit is thus: L P = L W ΔL = 35 d() 11 d = 24 d() Increase in sound level of 6 units amounts to approx. 8 d and is specified in the diagram Fig. 22. Thus, the anticipated sound pressure level in the room amounts to: L Pges. = L P + 8 d = 24 d() + 8 d = 32 d() The value for increased requirements, as specified in Fig. 21, is thus reached.

73 Flex-Geko omfort Edition NR and N limiting curves Limiting curves If narrower frequency components or outstanding single tones with high intensity peaks occur in a broad frequency range (e.g. on a fan), the d() specification (sum level) is not sufficient as the latter does not sufficiently address the annoying noise nature. Thus, for the purposes of noise evaluation, so-called limiting curves (curves which produce the same level of inconvenience) are added. These curves also consider the combination of noise frequencies. lthough various noise-rating curves are in place, NR (Noise Rating) curves specified in Fig. 26 became internationally accepted. Today N curves (Noise riteria) are only used for noise rating in the US, as specified in diagram Fig. 27. If the observance of a particular NR or N limiting curve is required for a room, the measured sound pressure may not exceed this limiting curve in any octave. The sum level across all eight octaves bands as per DIN is always around 7 to 10 d higher than the value in the limiting curve. For HV equipment the difference of the sound pressure level lies in the medium range at 5 d() because the noise spectrum does not always reach the same limiting curve in all octaves. Sound pressure level in d ISO NR evaluation curves Octave band/mean frequency Example The requirement of NR 28 or N 26 must be observed. The basis is the tabulated data on Page 70. In order to identify the sound pressure level in the individual octaves, the sound power values should be entered for size 3 and speed 2 in a table, see Fig. 25. In order to obtain the sound pressure levels in the individual octaves, 11 d must be subtracted from the sound power specifications entered in Fig. 25. The new values can now be entered in the nomograms Fig. 26 (NR) or Fig. 27 (N). The highest point in the NR evaluation stands at NR 20 (500 Hz) and N 18 (500 Hz) in the N evaluation. The requirement of NR 28 (NR 20 lies below NR 28) or N 26 (N 18 is below N 26), is thus met.

79 Flex-Geko omfort Edition ccessory sizes Geko-Drive What is Geko-Drive? Geko-Drive is a modern motorized discharge profile for optimization of flow velocity and air throw in cooling mode. Depending on fan speed (stage) as well as supply and room temperature, the main function is to improve air throw and indoor air flow and thence enhance room comfort. Variable cross-section Discharge profile is performed for most favorable air flow and reaches optimal discharge velocity even at low speed or speed stage. Geko-Drive is delivered already mounted by factory With unit casing for an optimum air routing system MTRIX 4000 controlling for automatic air throw adjustment vailable for only cooling or cooling and heating units using water as medium Model size Order No. Medium connection Left Right 1 ZGF.1412 ZGF Weight [kg] 2 ZGF.2412 ZGF ZGF.3412 ZGF ZGF.4412 ZGF ZGF.5412 ZGF ZGF.6412 ZGF ZGF.7412 ZGF ZGF.8412 ZGF Fig. 57 Example (computational fluid dynamics FD): Due to low cooling demand in part-load range, automatic regulation selects low fan speed (stage). This can lead to a situation when air discharge velocity is not adequate to reach an effective air throw and penetration depth up to ceiling. In an extreme case this can even lead an airside short circuit, when cold air is discharged from unit, falls down due to a missing impulse and sucked again into the unit. To avoid this, the speed (stage) would have to be increased which is not really desirable in terms of possibly low noise level and current draw. Geko-Drive works against above-mentioned scenario by reducing air discharge cross-section using continuous regulation, in such a way air flow velocity is increased without having to raise speed (stage) and at the same time air flow is evenly distributed on walls and ceiling (oanda-effect). Thus, an appreciable increase in penetration depth of the room can be reached as far as comfort is concerned and non-critical temperature and velocity-related distribution in occupied zone are ensured. with Geko- Drive Occupied zone* without Geko- Drive Occupied zone* Temperature in * conforming with DIN EN Fig. 58 PR G Subject to change R5-01/

94 System Description Flex-Geko omfort Edition Overview Normal/ economy mode buttons Speed stage selection switch Valve actuator type 2 point (modulating) 3 point (modulating) LEDs for status/fault/ external control Setpoint temperature switch MTRIX 2000 MTRIX 2000 control system supports all basic functions (heating/cooling) of recirculating-air fan coil unit and can be used in the following unit types: 2-pipe units only heating 2-pipe units only cooling 2-pipe units cooing or heating (change over) 4-pipe unit cooling and heating The assignment of speed stage can be carried out manually in a 3-speed mode or automatically in a 3-speed mode based on the deviation of actual temperature from the setpoint. Valves with on/off or 2-point modulating control behavior and a supply voltage of 230 V can be activated to control the heating and/or cooling capacity. With 2- pipe units 3-point modulating valve actuators can alternatively be controlled as well. The operation of 24 V valve actuators is possible as well (transformer by others required). The direct connection of an external room temperature sensor is not possible with changeover units, but can be performed via a Global Module. n alarm signal can also be processed by a Global module. Direct tapping is not possible. dditionally, the MTRIX 2000 enables monitoring of the fan motor via thermal contacts with external leads as well as the condensate water level for cooling units with a condensate pump. n alarm signal can also be processed by a Global module. Direct tapping via floating contacts is not possible. The connected sensors are monitored as well. The OP2000 control panel enables the setpoint values to be set quickly and easily without extensive prior experience. Mechanical limit stops can be used to limit the setting range for the setpoint temperature and speed stage. Room temperature is measured via a sensor integrated in the control panel. If the control panel is positioned in an unfavorable location (such as by the door), an external temperature sensor or return air sensor can be connected (not possible on changeover systems). System faults are signaled centrally via the red malfunction LED and output using a changeover contact. If economy mode is activated, it is displayed via the yellow LED integrated into the button. In addition to protection class IP20 (OP21 ), an OP21 l control panel in protection class IP54 for moist areas can be used. The connection in the unit is made via plug-in cage clamps. Electronics, fans and valves (230V) are fused separately via two pre-fuses on the power supply. fuse of 10 type must be supplied to provide the necessary circuit protection. The MTRIX 2000 can be used for controlling individual recirculating-air units and recirculating-air unit groups as well.

This control panel can be integrated at any location within the MTRIX network and can be simultaneously operated in 16 groups. Up to 16 unit groups can be assigned to one cluster: One unit group per each cluster Each cluster to include up to 16 unit groups. lear text menus and "push&turn" function enable easy handling during operation or configuration. maximum of 16 unit groups can be individually grouped to clusters. Using a control panel the desired setpoints for temperature, fan speed, etc. can be assigned for each cluster. Thanks to comprehensive features of the control panel, the necessary room or return air sensors are located in the respective groups (group locations). Local control panels (OP2xx, OP3xx, OP4xx, OP5x) can be additionally integrated in individual groups. Their functional scope can be defined and adjusted using the control panel for all groups. Thus, a relative daily setpoint can be entered via a local control panel, whereas the standard setpoint is assigned via the OP71. The integrated clock timer enables to assign 8 weekly programmes to clusters at any sequence. Each weekly programme enables to enter four switching times per day (2 x On/2 x Off), that can also be set to be valid for the whole day. In addition, it is possible to set 8 special switching days with up to four switching times (2 x On/2 x Off) per designated switching day. Holidays / bank holidays can be set using the calendar annual programme. On holidays the unit can be set to operate in "unit off" or economy mode. The summer / winter time changeover is performed automatically. The control unit is currently supplied with 7 selectable languages: German English French Dutch Polish zech Hungarian.
