English
Ensure that the supply voltage for these terminals cannot
be switched off by the tariff contactor when connecting
the mains cable for the well pump, in order to safeguard
the switch-off delay of the well pump.
12) The return flow sensor is integrated into the heat pumps.
The return flow sensor must be installed in the immersion
sleeve in the manifold only when a dual differential pres-
sureless manifold is used. The single-core wires are then
connected to terminals X3/GND and X3/ R2.1. Bridge A-
R2 (situated between X3/U2 and X3/1 when delivered)
must then be moved to terminals X3/1 and X3/2.
13) The external sensor (R1) is connected to terminals X3/GND
and X3/R1.
14) The domestic hot water sensor (R3) is included with the
domestic 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 addition-
ally be secured with a strain relief.
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.

Start-Up

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. These measures can also include an addi-
tional warranty under certain conditions (see Warranty). Start-
up should be carried out in heating operation.

8.2 Preparation

Prior to commissioning, the following items need to be
checked:
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 sole inlet of the

heat pump.
In the brine and heating circuits all valves that might impair

the proper flow must be open.
 The settings of the heat pump manager must be adapted
to the heating installation in accordance with the instruc-
tions contained in the controller's operating manual.

8.3 Procedure

The start-up of the heat pump is effected via the heat pump
manager.
ATTENTION!
Commissioning is to be effected in accordance with the
installation and operating manual of the heat pump manager.
