COMMISSIONING WITHOUT HEAT PUMP
The indoor module can be used without a heat pump, i.e
only as an electric boiler, to produce heat and hot water
before the heat pump is installed, for example.
Connect the pipe for docking in from the heat pump (XL8)
with the pipe out to the heat pump (XL9).
Enter menu 5.2.2 System settings and deactivate the heat
pump.
NOTE
Select operating mode "auto" if the indoor module
is to be used as an electric boiler without a heat
pump.

POST-ADJUSTMENT, VENTING
Initially, air is released from the hot water and venting may
be necessary. If gurgling sounds can be heard from the cli-
mate system, the entire system will require additional
venting. Vent the installation through the vent valves
(QM20). When venting, VVM 310 must be off.
