8) The heat circulating pump (M13) is activated via the con-

tact N1-J13/NO5. The connection points for the pump are

X2/M13 and X2/N. When using pumps where the switch-

ing capacity exceeds the output, a coupling relay must be

interposed.

9) The auxiliary circulating pump (M16) is activated via the

contact N1-J16/NO9. The connection points for the pump

are X2/M16 and X2/N. A coupling relay is already inte-

grated in this output.

10) The domestic hot water circulating pump (M18) is acti-

vated via the contact N1-J13/NO6. The connection points

for the pump are X2/M18 and X2/N. When using pumps

where the switching capacity exceeds the output, a cou-

pling relay must be interposed.

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

output.

12) The return sensor (R2) is integrated in the heat pumps for

indoor 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

domestic 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

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.

CAUTION!

It is not permitted to connect more than one electronically

regulated circulating pump via a relay output.

8 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.

The dirt trap must be inserted in the brine inlet of the heat

pump.

All valves that could impair proper flow in the brine and

heating circuits must be open.

The heat pump manager must be adapted to the heating

system in accordance with the controller's operating in-

structions.

8.3 Commissioning procedure

The heat pump is commissioned via the heat pump manager.

CAUTION!

Start-up must be performed in accordance with the

installation and operating instructions of the heat pump

manager.
