2. General information
These installation and operating instructions are a supplement to
installation and operating instructions for the corresponding
standard pumps TP, TPD. For instructions not mentioned
specifically here, please see installation and operating
instructions for the standard pump.
3. General description
Grundfos TPE, TPED Series 2000 pumps have standard motors
with integrated frequency converter. The pumps are for single-
phase or three-phase mains connection.
The pumps have a built-in PI controller and are set up with a
differential-pressure sensor enabling control of the differential
pressure across the pump.
The pumps are typically used as circulator pumps in large heating
or cooling water systems with variable demands.
3.1 Settings
The desired setpoint can be set in three different ways:
• directly on the pump control panel.
It is possible to choose between two different control modes,
i.e. proportional pressure and constant pressure.
• via an input for external setpoint signal
• by means of the Grundfos wireless remote control R100.
All other settings are made by means of the R100. Important
parameters such as actual value of control parameter, power
consumption, etc. can be read via the R100.
3.2 Twin-head pumps
Twin-head pumps do not require any external controller.

approx. 5 seconds.
If a higher number of starts and stops is desired, use the input for
external start/stop when starting/stopping the pump.
When the pump is switched on via an external on/off switch, it will
start immediately.
5.2.9 Connections
As a precaution, the wires to be connected to the following
connection groups must be separated from each other by
reinforced insulation in their entire lengths:
Group 1: Inputs
• start/stop, terminals 2 and 3
• digital input, terminals 1 and 9
• setpoint input, terminals 4, 5 and 6
• sensor input, terminals 7 and 8
• GENIbus, terminals B, Y and A
All inputs (group 1) are internally separated from the mains-
conducting parts by reinforced insulation and galvanically
separated from other circuits.
All control terminals are supplied with protective extra-low
voltage (PELV), thus ensuring protection against electric
shock.
Group 2: Output (relay signal, terminals NC, C, NO)
The output (group 2) is galvanically separated from other
circuits. Therefore, the supply voltage or protective extra-low
voltage can be connected to the output as desired.
Group 3: Mains supply (terminals N, PE, L)
Group 4: Communication cable (8-pin male socket) - only
TPED
The communication cable is connected to the socket in group
4. The cable ensures communication between the two pumps,
whether one or two pressure sensors are connected. See
section 5.7 Communication cable for TPED pumps.
The selector switch in group 4 enables changeover between
the operating modes "alternating operation" and "standby
operation". See the description in section 6.2.1 Additional
operating modes - TPED pumps.

faults:
• temporary overload
• fault in the power supply.
5.3.9 Connections
As a precaution, the wires to be connected to the following
connection groups must be separated from each other by
reinforced insulation in their entire lengths:
Group 1: Inputs
• start/stop, terminals 2 and 3
• digital input, terminals 1 and 9
• setpoint input, terminals 4, 5 and 6
• sensor input, terminals 7 and 8
• GENIbus, terminals B, Y and A
All inputs (group 1) are internally separated from the mains-
conducting parts by reinforced insulation and galvanically
separated from other circuits.
All control terminals are supplied with protective extra-low
voltage (PELV), thus ensuring protection against electric
shock.
Group 2: Output (relay signal, terminals NC, C, NO)
The output (group 2) is galvanically separated from other
circuits. Therefore, the supply voltage or protective extra-low
voltage can be connected to the output as desired.
Group 3: Mains supply (terminals N, PE, L)
Group 4: Communication cable (8-pin male socket) - only
TPED
The communication cable is connected to the socket in group
4. The cable ensures communication between the two pumps,
whether one or two pressure sensors are connected. See
section 5.7 Communication cable for TPED pumps.
The selector switch in group 4 enables changeover between
the operating modes "alternating operation" and "standby
operation". See the description in section 6.2.1 Additional
operating modes - TPED pumps.
Fig. 8 Connection terminals TPE Series 2000
Caution
The number of starts and stops via the mains voltage
must not exceed four times per hour.
Note
If a pump set up for automatic restart is stopped due
to a fault, it will restart automatically when the fault
has disappeared.

5.4.3 Backup fuses
For recommended fuse sizes, see section 20.1 Supply voltage.
5.4.4 Additional protection
If the pump is connected to an electric installation where an earth
leakage circuit breaker (ELCB) is used as additional protection,
the circuit breaker must be of a type marked with the following
symbols:
This circuit breaker is type B.
The total leakage current of all the electrical equipment in the
installation must be taken into account.
The leakage current of the motor in normal operation can be seen
in section 22.3 Leakage current.
During start and at asymmetrical supply systems, the leakage
current can be higher than normal and may cause the ELCB to
trip.
5.4.5 Motor protection
The pump requires no external motor protection. The motor
incorporates thermal protection against slow overloading and
blocking (IEC 34-11, TP 211).
5.4.6 Protection against mains voltage transients
The pump is protected against mains voltage transients in
accordance with EN 61800-3 and is capable of withstanding a
VDE 0160 pulse.
The pump has a replaceable varistor which is part of the transient
protection.
Over time this varistor will be worn and need to be replaced.
When the time for replacement has come, the R100 and PC Tool
E-products will indicate this as a warning. See section
19. Maintenance and service.
5.4.7 Supply voltage and mains
3 x 380-480 V - 10 %/+ 10 %, 50/60 Hz, PE.
The supply voltage and frequency are marked on the pump
nameplate. Make sure that the motor is suitable for the power
supply of the installation site.
The wires in the terminal box must be as short as possible.
Excepted from this is the protective earth conductor which must
be so long that it is the last one to be disconnected in case the
cable is inadvertently pulled out of the cable entry.

5.5 Signal cables
• Use screened cables with a cross-sectional area of minimum
0.5 mm2and maximum 1.5 mm2for external on/off switch,
digital input, setpoint and sensor signals.
• Connect the screens of the cables to frame at both ends with
good frame connection. The screens must be as close as
possible to the terminals. See fig. 16.
Fig. 16 Stripped cable with screen and wire connection
• Always tighten screws for frame connections whether a cable
is fitted or not.
• Make the wires in the pump terminal box as short as possible.
5.6 Bus connection cable
5.6.1 New installations
For the bus connection, use a screened 3-core cable with a
cross-sectional area of minimum 0.2 mm2and maximum 1.5 mm2.
• If the pump is connected to a unit with a cable clamp which is
identical to the one on the pump, connect the screen to this
cable clamp.
• If the unit has no cable clamp as shown in fig. 17, leave the
screen unconnected at this end.
Fig. 17 Connection with screened 3-core cable
5.6.2 Replacing an existing pump
• If a screened 2-core cable is used in the existing installation,
connect it as shown in fig. 18.
Fig. 18 Connection with screened 2-core cable
• If a screened 3-core cable is used in the existing installation,
follow the instructions in section 5.6.1 New installations.
5.7 Communication cable for TPED pumps
The communication cable is connected between the two terminal
boxes. The screen of the cable is connected to the frame at both
ends with a good frame connection.
Fig. 19 Communication cable
The communication cable has a master end and a slave end as
shown in fig. 20.
Fig. 20 Master end and slave end
On pumps with factory-fitted sensor, the master end and the
sensor are connected to the same terminal box.
When the power supply to the two pumps has been switched off
for 40 seconds and switched on again, the pump connected to the
master end will start up first.
5.7.1 Connection of two sensors
The sensor signal is copied to the other pump through the red
wire of the communication cable.
If, optionally, two sensors are connected (one sensor to each
terminal box), cut the red wire. See fig. 21.

6. Modes
Grundfos E-pumps are set and controlled according to operating
and control modes.
6.1 Overview of modes
6.2 Operating mode
When the operating mode is set to Normal, the control mode can
be set to controlled or uncontrolled. See section 6.3 Control
mode.
The other operating modes that can be selected are Stop, Min. or
Max.
• Stop: The pump has been stopped.
• Min.: The pump is operating at its minimum speed.
• Max.: The pump is operating at ist maximum speed.
Figure 23 is a schematic illustration of min. and max. curves.
Fig. 23 Min. and max. curves
The max. curve can for instance be used in connection with the
venting procedure during installation.
The min. curve can be used in periods in which a minimum flow is
required.
If the power supply to the pump is disconnected, the mode setting
will be stored.
The remote control R100 offers additional possibilities of setting
and status displays. See section 9. Setting by means of R100.
6.2.1 Additional operating modes - TPED pumps
The TPED pumps offer the following additional operating modes:
•Alternating operation
Pump operation alternates every 24 hours. If the duty pump
stops due to a fault, the other pump will start.
•Standby operation
One pump is operating continuously. In order to prevent
seizing-up, the other pump is started for 10 seconds every 24
hours. If the duty pump stops due to a fault, the other pump
will start.
Select the operating mode by means of the selector switch in the
terminal box. See figures 5, 9and 15.
The selector switch enables changeover between the operating
modes "alternating operation" (left position) and "standby
operation" (right position).
The switches in the two terminal boxes of a twin-head pump must
be set to the same position. If the switches are positioned
differently, the pump will be in standby operation.
Twin-head pumps can be set and operated in the same way as
single-head pumps. The duty pump uses its setpoint setting,
whether it is made by means of the control panel, via the R100 or
via bus.
If the power supply to the pump is disconnected, the pump setting
will be stored.
The remote control R100 offers additional possibilities of setting
and status displays. See section 9. Setting by means of R100.
6.3 Control mode
The pump can be set to two primary control modes, i.e.
• proportional pressure
• constant pressure.
Furthermore, the pump can be set to constant curve.
Fig. 24 Controlled and uncontrolled operation
Proportional-pressure control
The head is reduced at falling water demand and increased at
rising water demand. See fig. 24.
Constant-pressure control
The pump maintains a constant pressure, irrespective of water
demand. See fig. 24.
Constant curve mode
The pump is not controlled. The curve can be set within the range
from min. curve to max. curve. See fig. 24.
The pumps have been factory-set to proportional pressure. See
section 6.4 Factory setting. In most cases, this is the optimum
control mode, and at the same time it consumes the least energy.
