SI 85 TUR
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.
7.6.3 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

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