WI 65TU - WI 95TU
11) The brine or well pump (M11) is activated via the contact N1-
J12/NO3. The connection points for the pump are X2/M11
and X2/N. A coupling relay is already integrated in this out-
put.
12) The return sensor (R2) is integrated in the heat pumps for in-
door installation.
The heat pump manager is connected via the following ter-
minals: X3/GND and X3/R2.
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 do-
mestic hot water cylinder and is connected to terminals X3/
GND and X3/R3.
7.5.3 Connection of electronically
regulated circulating pumps
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.

Commissioning

8.1 General Information

To ensure that commissioning is performed correctly, it should
only be carried out by an after-sales service technician author-
ised by the manufacturer. This may be a condition for an addi-
tional guarantee (see "Warranty service").

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.
 In the well water and heating circuits all valves that might im-
pair the proper flow must be open.
The heat pump manager must be adapted to the heating

system in accordance with the controller's operating instruc-
tions.

8.3 Commissioning procedure

The heat pump is commissioned via the heat pump manager.
ATTENTION!
Start-up must be performed in accordance with the installation and
operating instructions of the heat pump manager.
