English
11) The brine or well pump (M11) is activated via the contact
N1-J12/NO3. The connection points for the pump are X2/
M11 and X2/N. A coupling relay is already integrated in this
output.
12) The return sensor (R2) is integrated in the heat pumps for
indoor installation.
The heat pump manager is connected via the following ter-
minals: X3/GND and X3/U2.
13) The external sensor (R1) is connected to terminals X3/GND
and X3/U1.
14) The domestic hot water sensor (R3) is included with the
domestic hot water cylinder and is connected to terminals
GND and X3/U3.
7.5.3 Connection of electronically
regulated circulating pumps
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 commissioning is performed correctly, it should
only be carried out by an after-sales service technician author-
ised by the manufacturer. This may be a condition for an addi-
tional guarantee (see "Warranty service").

8.2 Preparation

The following items must be checked prior to commissioning:
All of the heat pump connections must be installed as de-

scribed 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.

8.3 Commissioning procedure

The heat pump is commissioned via the heat pump manager.
ATTENTION!
Start-up must be performed in accordance with the
installation and operating instructions of the heat pump
manager.
