2. 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) 80-120 FZ and UPE 100-120 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.

4.4 Twin-head pumps
Twin-head pumps offer these operating modes:
• alternating operation
• standby operation
• synchronous operation
• single-pump operation.
4.4.1 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).
Fig. 4 Non-return valve
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.
5. Electrical connection
The electrical connection and protection must be
carried out according to local regulations.
• The pump requires no external motor protection.
• Check that the supply voltage and frequency
correspond to the values stated on the pump
nameplate.

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.
Fig. 8 Pressure control
7.2 Control of twin-head pumps
The factory setting can be changed with the R100.
Fig. 9 Master and slave pumps
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.
7.2.1 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.
7.2.2 R100 remote control
Single-pump operation is to be selected with the
R100. See section 8.6.6 Twin-head pump.
7.2.3 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.
7.2.4 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.

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 7.3.1 Setting in
connection with pump replacement.

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.
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.
Fig. 10 Max. and min. curves
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.

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 Tmax.. The setpoint is reduced in relation to
the head set (= 100 %) according to the
characteristics below.
Fig. 12 Temperature influence
In the above example, Tmax. = 80 °C has been
selected. The actual liquid temperature Tactual
causes the setpoint for head to be reduced from
100 % to Hactual.
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
two-pipe 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 Tmax.
In systems with a flow-pipe temperature of
• up to and including 55 °C, select Tmax. = 50 °C.
• above 55 °C, select Tmax. = 80 °C.
7.7 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.

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
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.
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.

deactivated to prevent unauthorised persons from
operating the pump.
7.12 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.
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 8.6.5 Pump
number and 8.7 Priority of settings.
7.13 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 R100.

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.
8.4.1 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.
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.
8.4.2 Operating mode
Select an operating mode:
•Stop
• Min. (min. curve)
• Normal (proportional pressure, constant pressure
or constant curve)
• Max. (max. curve).
8.4.3 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.
8.5.1 Actual setpoint
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.
8.5.2 Operating mode
This display shows the actual operating mode (Stop,
Min., Normal or Max.) and where this was selected
(Pump, R100, Bus or External).
Note
The display "Contact with" appears
only once, i.e. when the R100 gets
contact with the pump.
