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
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 con-
tactor or be connected to the household current, as impor-
tant 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 ac-
cording to the radiator output and must be supplied by the
customer. It is controlled (230 V AC) by the heat pump
manager via terminals 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 ra-
diator output and must be supplied by the customer. It is
controlled (230 V AC) by the heat pump manager via termi-
nals X2/N and X2/K21.
6)
The contactors mentioned above in points 3, 4 and 5 are
installed in the electrical distribution system. The mains
cable for the installed pipe heater must be laid and secured
in accordance with the valid standards and regulations.
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 or well pump (M11) is connected to terminalsX2/
N and X2/M11 and PE.
11) The return flow sensor is integrated into the heat pumps
and is connected to the heat pump manager via the control
line. The return flow sensor must be installed in the immer-
sion sleeve in the manifold only 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 terminals 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
domestic hot water cylinder and is connected to terminals
X3/GND and X3/R3.

7.5.3 Connecting an electronically
regulated circulating pump
Electronically regulated circulating pumps have high starting
currents, which may shorten the service life of the heat pump
manager. For this reason, a coupling relay is installed or must be
installed between the output of the heat pump manager and
the electronically regulated circulating pump. This is not neces-
sary if the permissible operating current of 2 A and a maximum
starting current of 12 A are not exceeded in the electronically
regulated circulating pump or if express approval has been is-
sued by the pump manufacturer.
ATTENTION!
It is not permitted to connect more than one electronically
regulated circulating pump via a relay output.

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. These measures can also include an addi-
tional warranty under certain conditions (see Warranty).
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 7.
The heat source system and the heating circuit must have
been filled and checked.
The dirt trap must be inserted in the brine inlet of the heat
pump.
All valves that could impair proper flow in the brine and
heating circuits must be open.
The heat pump manager must be adapted to the heating
system in accordance with the controller's operating in-
structions.
