2)
The three-core supply cable for the heat pump manager
(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 cables must be installed as 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.
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.

All lines must be fed into the device from the back and secured
at the switch box using cable connectors. They must additionally
be secured with a strain relief.

8.1 General
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
Prior to commissioning, the following items need to be checked:
8.3 Procedure
The start-up of the heat pump is effected via the heat pump man-
ager.
Commissioning is to be effected in accordance with the installation and
operating manual of the heat pump manager.
452234.66.37 · FD 9205
Start-up
All connections of the heat pump must have been made as
described in Chapter 7.
The heat source system and the heating circuit must have
been filled and checked.
The strainer must have been fitted in the well water inlet of
the heat pump.
In the well water and heating circuits all valves that might im-
pair the proper flow must be open.
The settings of the heat pump manager must be adapted to
the heating installation in accordance with the instructions
contained in the controller's operating manual.
