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).
Select "Add. heat only" in menu 4.1 - "Operating mode".
Enter menu 7.3.2 - "Installed heat pump" and deactivate the
heat pump.
NOTE
Select operating mode "auto" or "manual", when
the indoor module is to be used again with the
air/water 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. The installation is vented via vent valves (QM20),
(QM22) and other climate systems through their relevant
vent valves. When venting, VVM S320 must be off.
