opening distance (e.g. utility protection contactor, power
contactor), as well as an all-phase cutout switch, with shared
activation of all external conductors (release currents and
characteristics in accordance with device information; see
circuit diagram for further details).
ATTENTION!
Ensure that there is a clockwise rotating field: With incorrect wiring the
starting of the heat pump is prevented. A corresponding warning is
indicated on the display of the heat pump manager (adjust wiring).
2) The three-core electric supply cable for the heat pump man-
ager (heating controller N1) is fed into the heat pump.
Connection of the control line to the control panel of the heat
pump via terminal X2: L/N/PE.
Details on the power consumption of the heat pump are
listed on both the product information sheet and the type
plate.
The (L/N/PE ~230 V, 50 Hz) supply cable for the heat pump
manager must have a constant voltage. For this reason, it
should be tapped upstream from the utility blocking contac-
tor or be connected to the household current, as important
protection functions could otherwise be lost during a utility
block.
3) The utility blocking contactor(K22) with 3 main contacts (1/3/
5 // 2/4/6) and an auxiliary contact (NO contact 13/14)
should be dimensioned according to the heat pump output
and must be supplied by the customer.
The NO contact of the utility blocking contactor (13/14) is
looped from terminal strip X3/G to connector terminal X3/A1.
CAUTION! Extra-low voltage!
4) The contactor (K20) for the immersion heater (E10) of mono
energy systems (HG2) should be dimensioned according to
the radiator output and must be supplied by the customer. It
is controlled (230 V AC) by the heat pump manager via ter-
minals X2/N and
X2/K20.
5) The contactor (K21) for the flange heater (E9) in the hot
water cylinder should be dimensioned according to the radi-
ator output and must be supplied by the customer. It is con-
trolled (230 V AC) by the heat pump manager via terminals
X2/N and
X2/K21.
6) The contactors mentioned above in points 3, 4 and 5 are in-
stalled in the electrical distribution system. The mains cables
for the heating elements should be dimensioned and pro-
tected according to DIN VDE 0100.
7) All installed electric cables must have permanent wiring.
8) The heat circulating pump (M13) is connected to terminals
X2/N and X2/M13.
9) The DHW loading pump (M18) is connected to terminals X2/
N and X2/M18.
10) The brine and/or well pump (M11) is connected to terminals
2/4/6 of K5 and PE. If an additional well pump is used, the
protective motor switch at the site must be checked and re-
placed if necessary.
11) A return sensor is integrated into the heat pump. The return
flow sensor must be installed in the immersion sleeve in the
manifold when a dual differential pressureless manifold is
used. The single-core wires are then connected to terminals
X3/GND and X3/ R2.1. Bridge A-R2 (situated between X3/
B2 and X3/1 when delivered) must then be moved to termi-
nals X3/1 and X3/2.
12) The external sensor (R1) is connected to terminals X3/GND
and X3/R1.
13) The domestic hot water sensor (R3) is included with the do-
mestic hot water cylinder and is connected to terminals X3/
GND and X3/R3.
8 Commissioning
8.1 General Information
To ensure that start-up is performed correctly, it should only be
carried out by an after-sales service technician authorised by the
manufacturer. This may be a condition for extending the guaran-
tee (see Warranty Service).
8.2 Preparation
The following items need to be checked prior to start-up:
 The heat pump must be fully connected, as described in
Chapter 6.
 The heat source system and the heating circuit must have
been filled and checked.
 All valves that could impair proper flow in the well and heat-
ing circuits must be open.

The heat pump manager must be adapted to the heating
system in accordance with the controller’s operating instruc-
tions.
8.3 Start-up Procedure
The heat pump is started up via the heat pump manager.
ATTENTION!
The heat pump must be started up in accordance with the installation and
operating instructions of the heat pump manager.
If an overflow valve is fitted to assure the minimum heating water
flow rate, the valve must be set in accordance with the require-
ments of the respective heating system. Incorrect adjustment
can lead to faulty operation and increased energy consumption.
We recommend carrying out the following procedure to correctly
adjust the overflow valve:
Close all of the heating circuits that may also be closed during
operation (depending on the type of heat pump usage) so that
the most unfavourable operating state - with respect to the water
flow rate - is achieved. This normally means the heating circuits
of the rooms on the south and west sides of the building. At least
one heating circuit must remain open (e.g. bathroom).
The overflow valve should be opened far enough to produce the
maximum temperature spread between the heating flow and re-
turn flow listed in the table below for the current heat source tem-
perature. The temperature spread should be measured as close
as possible to the heat pump. The heating element of mono en-
ergy systems should be disconnected during start-up.
