English
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.
7.6.3 Connecting an electronically
regulated circulating pump
Electronically regulated circulating pumps have high starting cur-
rents, which may shorten the service life of the heat pump man-
ager. For this reason, a coupling relay is installed or must be in-
stalled between the output of the heat pump manager and the
electronically regulated circulating pump. This is not necessary 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 issued 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 additional
warranty under certain conditions (see Warranty). Start-up
should be carried out in heating operation.

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 in the brine circuit (on the hydraulic 4-way re-
versing valve) must be installed.
 All valves that could impair proper flow in the brine 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.
 The mounted hydraulic 4-way reversing valve assembly
must be adequately insulated on-site once the installation is
complete.

8.3 Procedure

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