2) The three-core electric supply cable for the heat pump man-
ager (heating controller N1) is fed into the heat pump.
Connection of the control line to the switch box of the heat
pump via terminals 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 contac-
tor or be connected to the household current, as important
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 terminal X3/A1.
CAUTION! Extra-low voltage! The contactor is installed in
the electrical distribution system. Mains cables for the
installed heaters must be laid and secured in accordance
with the valid standards and regulations.
4) All installed electric cables must have permanent wiring.
5) The external sensor (R1) is connected to terminals X3/GND
(ground) and X3/R1.
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. A coupling relay is therefore installed or must be installed
between the output of the heat pump manager and the electron-
ically regulated circulating pump. This is not necessary if the
maximum permissible operating current of the heat pump man-
ager of 2 A and the maximum permissible starting current of the
heat pump manager of 12 A are not exceeded by the electroni-
cally regulated circulating pump or a relevant 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.

Commissioning

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).

8.2 Preparation

The following items must be checked prior to start-up:
 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.
 Dirt traps and breathers must be inserted in the brine inlet of
the heat pump.
 All valves that could impair proper flow in the brine and heat-
ing circuits must be open.
 The heat pump manager must have been parametered for
the relevant hydraulics in accordance with its operating
instructions.

8.3 Start-up procedure

The heat pump is started up via the heat pump manager.
ATTENTION!
The heat pump must be started up in accordance with the installation and
operating instructions of the heat pump manager.
The overflow valve must be adjusted to the requirements of the
respective heating system. Incorrect adjustment can lead to
faulty operation and increased energy consumption. We recom-
mend carrying out the following procedure to set the overflow
valve correctly:
Close all of the heating circuits that may also be closed during
operation so that the most unfavourable operating state - with re-
spect to the water flow - is achieved. This normally means the
heating circuits of the rooms on the south and west sides of the
building. At least one heating circuit must remain open (e.g. bath-
room).
The overflow valve should be opened far enough to produce the
maximum temperature spread between the heat flow and heat
return flow listed in the following table for the current heat source
temperature. The temperature spread should be measured as
close as possible to the heat pump. The heating element of mono
energy systems should be disconnected during start-up.
