this reason, it should be tapped upstream from the utility
blocking contactor or be connected to the household
current, as important protection functions may 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 connector terminal N1-J5/
ID3. CAUTION! Extra-low voltage!
4) The contactor (K21) for the flange heater (E9) in the hot
water cylinder should be dimensioned according to the
radiator output and must be supplied by the customer. It is
controlled (230 V AC) by the heat pump manager via
terminals X2/N and N1-J16/NO10.
5) The contactors mentioned above in points 3 and 4 are in-
stalled in the electrical distribution system. Mains cables for
the installed heaters must be laid and secured in accord-
ance with the valid standards and regulations.
6) All installed electric cables must have permanent wiring.
7) The heat circulating pump (M13) is connected to N1-J13/
NO5 and X2/N. When using pumps where the switching
capacity exceeds the output, a coupling relay must be
interposed.
8) The domestic hot water circulating pump (M18) is connected
to N1-J13/NO 6 and X2/N. When using pumps where the
switching capacity exceeds the output, a coupling relay must
be interposed.
9) The return sensor (R2) is integrated into air-to-water heat
pumps for indoor installation.
The connection to the HPM is made at terminals X3/GND
and N1-J2/B2.
10) The external sensor (R1) is connected to terminals X3/GND
and N1-J2/B1.
11) The domestic hot water sensor (R3) is included with the
domestic hot water cylinder and is connected to terminals
X3/GND and N1-J2/B3.
7.5.3 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.

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).

8.2 Preparation

The following items need to be checked prior to start-up:
 All of the heat pump connections must be established as de-
scribed in Chapter 6.
 All valves that could impair the proper flow of the heating
water in the heating circuit must be open.
 The air intake and air outlet paths must be clear.
 The ventilator must turn in the direction indicated by the ar-
row.
 The heat pump manager must be adapted to the heating
system in accordance with the controller's operating instruc-
tions.
 Ensure the condensate outflow functions properly.
 The outflow from the heating water pressure relief valve
must also function correctly.
 De-aeration of the heating system:
Ensure that all heating circuits are open and the heat circu-
lating pump is operating (level III).
Connect the voltage to the heat pump manager. Select the
heat generator 2 operating mode and de-aerate the system
at its highest point. Top up with water if required (maintain
static minimum pressure).
 Prior to start-up, it is essential to remove the two transport
restraint screws (M6 - see illustration) which are labelled
with stickers on the compressor panel!
ATTENTION!
Operating the heat pump without removing the transport restraint screws
not only produces increased sound emission, but can also cause damage
to the compressor and the refrigerant pipes.
