Readjusting, venting, heat medium side
Air is initially released from the hot water and venting
may be necessary. If gurgling sounds can be heard from
the heat pump or climate system, the entire system will
require additional venting.

Check the fluid level in the level vessel
(CM2). If the fluid level has dropped, top up
the system.
1.
Close the valve under the vessel.
2.
Disconnect the connection on top of the
vessel.
3.
Fill with brine until approx 2/3 of the
vessel is full.
4.
Reconnect the connector at the top of
the vessel.
5.
Open the valve under the vessel.
If the pressure in the system needs to be raised, this is
done by closing the valve on the outgoing main line
when the brine pump (GP2) is in operation and the level
vessel (CM2) is open, so that liquid is drawn down from
the vessel.
Expansion vessel
If a pressure expansion vessel (CM3) is used
instead of a level vessel, the pressure level
is checked. If the pressure drops, the system
should be replenished.
Post adjusting the room temperature
If the required room temperature is not obtained, read-
justment may be necessary.
Cold weather conditions
■
When the room temperature is too low, increase
"heating curve" in menu 1.9.1.1 by one increment.
■
When the room temperature is too high, reduce
"heating curve" in menu 1.9.1.1 by one increment.
Warm weather conditions
■
When the room temperature is too low, increase
"temperature" (offset heating curve) in menu 1.1.1 by
one increment.
■
When the room temperature is too high, reduce
"temperature" (offset heating curve) in menu 1.1.1 by
one increment.
