General description The Grundfos UPE(D) FZ is a range of circulator pumps with differential-pressure control enabling adjustment of the pump performance to the actual system requirements. In many systems, this will reduce the power consumption considerably, reduce noise from thermostatic valves and similar fittings, and improve the control of the system. The desired head can be set on the pump control panel. These instructions apply to the pump types UPE(D) FZ and UPE FZ. The pump offers the following functions: Proportional-pressure control (factory setting). The pump head is changed in accordance with the flow demand. The desired head can be set on the pump control panel. Constant-pressure control. A constant head is maintained, irrespective of the flow demand. The desired head can be set on the pump control panel. Constant-curve duty. The pump runs at a constant speed on or between the max. and min. curves. 6

7 Temperature influence. The pump head varies depending on the liquid temperature. External fault signal via a potential-free output. External analog control of head or speed from an external 0-10 V signal transmitter. External forced control via inputs for start/stop min. curve. Bus communication. The UPE(D) FZ circulator pumps incorporate an input for bus communication. The pump can be controlled and monitored by a building management system. Remote control. The pump can be operated with the Grundfos R100 remote control. 3. Applications The UPE(D) FZ circulator pumps are designed for circulating liquids in heating systems. The UPE(D) FZ range is suitable for systems with a constant flow where it is desirable to optimise the setting of the pump duty point. systems with variable flow-pipe temperatures. 3.1 Pumped liquids Thin, clean, non-aggressive and non-explosive liquids, not containing solid particles, fibres or mineral oil. In heating systems, the water should meet the requirements of accepted standards on water quality in heating systems, for example the German standard VDI Mounting the pressure sensor Mount the pressure sensor only after Note the pump has been installed in the system. See fig Place the O-ring in the seat of the pump housing. 2. Place the sensor housing without damaging the O-ring. 3. Fit and tighten the two screws. Fig. 1 Mounting the pressure sensor 4.3 Control box positions Note The control box must only be turned to the positions shown on page 310. The arrows show the allowed/possible flow directions Changing the control box position Warning Before any dismantling of the pump, the system must be drained, or the isolating valves on either side of the pump must be closed, as the pumped liquid may be scalding hot and under high pressure. TM English (GB) Warning The pump must not be used for the transfer of flammable liquids, such as diesel oil, petrol or similar liquids. 4. Installation 4.1 Positioning the pump The arrow on the pump housing indicates the liquid flow direction through the pump. Warning Make sure that persons cannot accidentally come into contact with the hot surfaces of the pump. The pump must be installed with the motor shaft horizontal. See mounting dimensions at the end of these instructions. Fig. 2 Correct control box position Change the control box position as follows: 1. Slacken the cable clamp of the pressure sensor. 2. Remove the four screws holding the pump head. 3. Turn the pump head to the desired position. 4. Refit the four screws and tighten securely. 5. Adapt the pressure sensor cable, and tighten the cable clamp. Warning Make sure that the pressure sensor cable cannot come into contact with the pump head. TM

8 English (GB) 4.4 Twin-head pumps Twin-head pumps offer these operating modes: alternating operation standby operation synchronous operation single-pump operation Master pump and slave pump The master pump will always be the pump to the right when seen from the control box end and the pump is pumping upwards. See fig. 3, pos. 1. Fig. 3 Master pump (1) and slave pump (2) 4.5 Non-return valve If a non-return valve is fitted in the pipe system (fig. 4), it must be ensured that the minimum discharge pressure is always higher than the closing pressure of the valve. This is especially important in proportional-pressure control mode (reduced head at low flows). TM Electrical connection The electrical connection and protection must be carried out according to local regulations. Warning Never make any connections in the pump control box unless the power supply has been switched off for at least 5 minutes. The indicator light must be off. See fig. 6, pos. 21. The earth terminal of the pump must be earthed. The pump must be connected to an external mains switch with a minimum contact gap of 3 mm in all poles. Earthing or neutralisation can be used for protection against indirect contact. Megging must be carried out as described in section 10. Megging. If the pump is connected to an electric installation where an earth leakage circuit breaker (ELCB) is used as an additional protection, this circuit breaker must trip out when earth fault currents with DC content (pulsating DC) and smooth DC earth fault currents occur. The earth leakage circuit breaker must be marked with these symbols: Fig. 4 Non-return valve TM The pump requires no external motor protection. Check that the supply voltage and frequency correspond to the values stated on the pump nameplate. 5.1 Ferrite core Install the ferrite core as shown below. 4.6 Insulation If the pump is insulated without using Grundfos insulating kits, it must be ensured that the differential-pressure and temperature sensor in the pump housing is not covered. 4.7 Frost protection If the pump is not being used during periods of frost, the necessary steps must be taken to prevent frost bursts.

All cables used must be installed in accordance with EN Warning Wires connected to outputs 7 and 8, inputs 1 to 6, supply terminals and differential-pressure and temperature sensor must be separated from each other and from the supply by reinforced insulation. All wires connected to a terminal block must be tied up at the terminals. Concerning demands on signal wires and signal transmitters, see section 12. Technical data. 6. Start-up Do not start the pump until the system has been filled with liquid and vented. Furthermore, the required minimum inlet pressure must be available at the pump inlet. See section 12. Technical data. Note The system cannot be vented through the pump. 6.1 Venting the pump Vent the pump before start-up. See fig. 7. Warning When the vent screw is slackened, scalding hot liquid under high pressure may escape. Care must be taken to ensure that the escaping liquid does not cause personal injury or damage to other components. Vent screw TM TM Fig. 7 Venting the pump The pump may be noisy, when first switched on, due to air remaining in the pump. This noise should cease after a few minutes running. After start-up, set the desired operating mode and possibly pump head. 10

11 7. Functions Some functions can only be selected with the Grundfos R100 remote control. Where and how the various settings are made appear from section 8. Setting the pump. 7.1 Control modes The UPE(D) FZ pumps can be set to the control mode which is most suitable for the individual system. Two control modes are available: proportional pressure (factory setting) constant pressure. Proportional-pressure control To be set on the control panel or with the R100. The pump head is reduced at falling water demand and increased at rising water demand. See fig. 8. This is the factory setting as, in most cases, this is the optimum control mode, and at the same time it consumes the least energy. Constant-pressure control To be set on the control panel or with the R100. The pump maintains a constant pressure, irrespective of water demand. See fig. 8. H set H H set 2 Fig. 8 Pressure control 7.2 Control of twin-head pumps The factory setting can be changed with the R100. Fig. 9 Proportional pressure Slave pump Q H H set Constant pressure Master pump Master and slave pumps Q TM TM Four operating modes are available. The selection of operating mode depends on whether reliability, lifetime or performance has top priority. Alternating operation (factory setting). Pump operation alternates every 24 hours. If the power supply to the pump has been switched off, any of the pumps may start when the power supply is switched on again. Reaction in case of fault: In case of fault in one pump, the duty pump will operate continuously as a single-head pump. Standby operation. The master pump is operating continuously. Every 25 hours the slave pump will start and run for approx. 10 seconds to prevent it from seizing up. Reaction in case of fault: If the master pump stops due to a fault, the slave pump will operate continuously as a single-head pump. Synchronous operation. The pumps are operating at the same motor frequency. This operating mode is suitable if the flow demand exceeds the flow of one pump. Reaction in case of fault: In case of fault in one pump, the duty pump will operate continuously as a single-head pump. Single-pump operation. The pumps are operating completely independently of each other without internal communication, but the twin-head cable must be connected. All functions of each pump are identical to those of a single-head pump. All the other functions mentioned in sections 7.1 Control modes to 7.13 Remote control are possible in the four operating modes Why select single-pump operation Select single-pump operation when the twin-head pump is to be controlled or monitored by a Grundfos pump management system. in all other situations where the master and slave pumps are to operate independently of each other as two single-head pumps R100 remote control Single-pump operation is to be selected with the R100. See section Twin-head pump Operation in parallel In single-head operation mode, the pumps must never run at the same time, unless the pump is controlled by a Grundfos pump management system Setting the slave pump When single-pump operation mode has been selected, the slave pump settings will correspond to the settings of the last working pump. English (GB) 11

12 English (GB) 7.3 Selection of control mode Systems with specified control mode If the pump control mode (proportional or constant pressure) and head have been specified for the system in which the pump is to be installed, set the pump as specified. See section 8. Setting the pump. If problems should arise, see section 9. Fault finding. Systems with no specified control mode If the pump control mode and head have not been specified for the system (for instance, an uncontrolled standard pump is replaced by the UPE pump), it is advisable to use the settings in the table below and in section Setting in connection with pump replacement. System type 1. Relatively great head losses in the boiler circuit and the distribution pipes. 2. Relatively small head losses in the boiler circuit and the distribution pipes. Description a) Two-pipe heating systems with thermostatic valves and with a dimensioned pump head higher than 4metres, very long distribution pipes, strongly throttled pipe balancing valves, differential pressure regulators, great head losses in those parts of the system through with the total quantity of water flows (for example boiler, heat exchanger and distribution pipe up to the first branching) or low differential temperature. b) Underfloor heating systems and one-pipe heating systems with thermostatic valves and great head losses in the boiler circuit. c) Primary circuit pumps in systems with great head losses in the primary circuit. a) Two-pipe heating systems with thermostatic valves and with a dimensioned pump head lower than 2metres, dimensioned for natural circulation, small head losses in those parts of the system through with the total quantity of water flows (for example boiler, heat exchanger and distribution pipe up to the first branching) or modified to a high differential temperature (for example district heating). b) Underfloor heating systems with thermostatic valves. c) One-pipe heating systems with thermostatic valves or pipe balancing valves. d) Primary circuit pumps in systems with small head losses in the primary circuit. Select this control mode Proportional pressure Constant pressure 12

13 7.3.1 Setting in connection with pump replacement If an uncontrolled pump is to be replaced with a UPE(D) FZ pump, settings can be made according to the tables below. Existing pump Existing pump at maximum speed UPE(D) FZ Existing pump Existing pump at reduced speed UPE(D) FZ English (GB) Maximum head [m] Setting of head [m] Setting of control mode Read the tables as follows: If the maximum head of the existing pump is 6 metres and the pump is running at maximum speed under normal operating conditions, it is recommended to set the pump to 3 metres and to select proportional pressure. If, however, the existing pump is running at a reduced speed, it is recommended to set the pump to 2 metres and to select constant pressure. 7.4 Max. or min. curve duty To be set on the control panel, with the R100 or a building management system via bus. It is not possible to set max. curve duty via the external input. The pump can be set to operate according to the max. or min. curve, like an uncontrolled pump. See fig. 10. Maximum head [m] The max. curve mode can be selected if an uncontrolled pump is required. See section 8.2 Control panel. In this operating mode, the pump will operate independently of an external controller, if installed. The min. curve mode can be used in periods in which a minimum flow is required. This operating mode is for instance suitable for night-time duty. 7.5 Constant-curve duty To be set with the R100. The pump can be set to operate according to a constant curve, like an uncontrolled pump. Select one of the curves between the max. and min. curves. See fig. 11. Fig. 11 Setting of head [m] Constant-curve duty Setting of control mode 3 2 Constant pressure Constant pressure 4 2 Constant pressure Constant pressure Proportional pressure 5 2 Constant pressure 6 3 Proportional pressure 6 2 Constant pressure Proportional pressure Proportional pressure 8 4 Proportional pressure 8 3 Proportional pressure Proportional pressure Proportional pressure 10 5 Proportional pressure Proportional pressure Proportional pressure 11 4 Proportional pressure 12 6 Proportional pressure 12 4 Proportional pressure H Min.

14 English (GB) 7.6 Temperature influence To be set with the R100. When temperature influence is activated in proportional- or constant-pressure control mode, the setpoint for head will be reduced according to the liquid temperature. It is possible to set temperature influence to function at liquid temperatures below 80 C or below 50 C. These temperature limits are called T max.. The setpoint is reduced in relation to the head set (= 100 %) according to the characteristics below. H % % H actual 3030% % 20 Fig. 12 Temperature influence In the above example, T max. = 80 C has been selected. The actual liquid temperature T actual causes the setpoint for head to be reduced from 100 % to H actual. The temperature influence function requires: Proportional- or constant-pressure control mode. The pump must be installed in the flow pipe. System with flow-pipe temperature control, for example according to outdoor temperature. Temperature influence is suitable in systems with variable flows (for example twopipe heating systems) in which the activation of the temperature influence function will ensure a further reduction of the pump performance in periods with small heating demands and consequently a reduced flow-pipe temperature. systems with almost constant flows (for example one-pipe heating systems and underfloor heating systems) in which variable heating demands cannot be registered as changes in the head as is the case with two-pipe heating systems. In such systems, the pump performance can only be adjusted by activating the temperature influence function. Selection of T max. In systems with a flow-pipe temperature of up to and including 55 C, select T max. = 50 C. above 55 C, select T max. = 80 C. H t [ C] T actual Q TM Indicator lights The two indicator lights are used for fault and operating indication. For position on pump (fig. 14), see section 8.2 Control panel. Note When the R100 remote control communicates with the pump, the red indicator light will flash rapidly. Functions of indicator lights Indicator lights Fault (red) Off Off Off Permanently on Permanently on Permanently on Operation (green) Off Permanently on Flashing Off Permanently on Flashing See also section 9. Fault finding. Description The power supply has been switched off. The pump is operating. The pump has been set to stop. The pump has stopped due to a fault. Restarting will be attempted. It may be necessary to restart the pump manually by resetting the fault indication. The pump is operating, but it has been stopped due to a fault. Note: If there is no differential-pressure or temperature sensor signal, the pump will continue operating according to the max. curve. The pump has been set to stop, but it has been stopped due to a fault. 14

15 7.8 External fault indication The pump incorporates a signal output for a potential-free fault signal via terminals 7 and 8. Functions of signal output Signal output Description The power supply has been switched off. The pump is operating. The pump has been set to stop. 7.9 External analog 0-10 V controller The pump has an input for an external 0-10 VDC analog signal transmitter (terminals 5 and 6). Via this input, the pump can be controlled by an external controller if the pump has been set to this control mode: Constant curve. The external analog signal will set the pump curve within the range from the min. curve to the constant curve selected according to the characteristic in fig. 13. At an input voltage lower than 0.5 V, the pump will operate according to the min. curve. The setpoint cannot be changed. The setpoint can only be changed when the input voltage is higher than 0.5 V. H m 1 2 English (GB) The pump has stopped due to a fault. Restarting will be attempted. It may be necessary to restart the pump manually by resetting the fault indication. The pump is operating, but it has been stopped due to a fault. Note: If there is no differentialpressure or temperature sensor signal, the pump will continue operating according to the max. curve. The pump has been set to stop, but it has been stopped due to a fault. The fault signal output is activated when the pump registers a fault. The fault signal relay is activated together with the red indicator light on the pump. Resetting of fault indications A fault indication can be reset in one of the following ways: Briefly press or on the pump. This will not influence the pump performance set. Briefly switch off the power supply to the pump. With the R100. See section 8.3 R100. The fault indication cannot be reset until the cause of the fault has disappeared. 0 Fig. 13 Pos.

H H Start/stop Q Q Min. curve Q Q Normal duty Stop Normal duty Min. curve (night-time duty) 7.11 Deactivating the control panel To be set with the R100. The buttons on the pump control panel can be deactivated to prevent unauthorised persons from operating the pump Bus communication The pump has a serial communication port which enables communication with the Grundfos Control MPC Series 2000, a CIM/CIU communication interface, a building management system or another type of external control system. If a CIU unit is installed in the system, it is possible to establish communication between the pump and a main network via one of the following protocols: LON Profibus DP Modbus RTU BACnet MS/TP. For further details, see the installation and operating instructions for the CIM and CIU. Via the bus signal, it is possible to remote-set pump operating parameters, such as desired head, temperature influence and operating mode. At the same time, the pump can provide status information about important parameters, such as actual head, actual flow, power input and fault indications. Note When the pump is controlled via a bus signal, the number of settings available on the pump control panel or via the R100 will be reduced. The pump head and control mode can only be set via the bus signal. The pump control panel or the R100 can only set the pump to max. curve and to stop. However, an R100 is required if a number is to be allocated to the pump. See sections Pump number and 8.7 Priority of settings Remote control The pump is designed for wireless communication with the Grundfos R100 remote control. The R100 communicates with the pump via infrared light. During communication, the R100 must be pointed at the pump control panel. When the R100 is communicating with the pump, the red indicator light will flash rapidly. The R100 offers additional setting options and status displays for the pump. See section 8.3 R

17 8. Setting the pump For the setting of the pump, use control panel R100 remote control bus communication (not described in detail in these instructions. Contact Grundfos). The table below shows the application of the individual operating units and in which section the function has been described.

21 8.4 Menu OPERATION When the communication between the R100 and the pump has been established, "Contact with" appears in the display. When the "arrow down" on the R100 is pressed, the OPERATION menu appears. Note The display "Contact with" appears only once, i.e. when the R100 gets contact with the pump Setpoint This display depends on the control mode selected in the display "Control mode" in the INSTALLATION menu. If the pump is remote- or forced-controlled via external signals, the number of possible settings will be reduced. See section 8.7 Priority of settings. Attempts to change the settings will result in an indication in the display saying that the pump is remote-controlled and that changes therefore cannot be made. The following example of display will appear if the pump is in proportional-pressure control mode Fault indications If the pump is faulty, the cause will appear in this display. Possible causes: Phase failure Pump blocked Undervoltage Defective pressure/temperature sensor Internal fault. The fault indication can be reset in this display. If the fault cause has not disappeared when resetting is attempted, this will be indicated in the display. 8.5 Menu STATUS The displays appearing in this menu are status displays only. It is not possible to change or set values. The actual values in these displays are stated as a guide Actual setpoint English (GB) Set the desired head. Furthermore, it is possible to select one of these operating modes: Stop Min. (min. curve) Max. (max. curve). This display will be a little different in the case of constant-pressure control or constant-curve duty. The actual duty point of the pump is indicated by a square in the Q/H field. No indication at low flow Operating mode Field "Actual setpoint": Actual setpoint of pump. Field "corresponding to": Actual setpoint in % of the setpoint set if the pump is connected to an external analog 0-10 V signal transmitter or if temperature influence or proportional-pressure control is activated Operating mode Select an operating mode: Stop Min.

Actual power input and power consumption of the pump. Power consumption is not calculated in UPE(D) FZ and UPE FZ Operating hours In this display, it is possible to choose between two min. curves. The curve is used when the operating mode "Min. curve" is selected. When controlling UPE(D) FZ and UPE FZ, only one min. curve is available Temperature influence Description of function, see section 7.6 Temperature influence. Number of operating hours of the pump. The value of operating hours is an accumulated value and cannot be set to zero. The temperature influence function can be activated in this display. In the case of temperature influence, the pump must be installed in the flow pipe. It is possible to choose between maximum temperatures of 50 C and 80 C. The temperature influence function will be active only in proportional- or constant-pressure control mode. When the temperature influence is active, a small thermometer is shown in the display "Setpoint" in the OPERATION menu. See section Setpoint. 22

23 Note If the pump is controlled via bus, temperature influence cannot be set with the R Buttons on pump 8.7 Priority of settings The external forced-control signals will influence the settings available on the pump and with the R100. The pump can always be set to max. curve duty or to stop on the pump control panel or with the R100. If two or more functions are activated at the same time, the pump will operate according to the function with the highest priority. The priority of the settings is as shown in the tables below. Without bus signal English (GB) To prevent unauthorised persons from operating the pump, the function of the buttons and can be deactivated in this display. The buttons can be reactivated only with the R100.
