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, it is raised
by closing the valve on the incoming main line when the
brine pump (GP2) is running 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.

The prescribed heating curve for your house can be
viewed in the menu heating curve . The task of the
heating curve is to give an even indoor temperature, re-
gardless of the outdoor temperature, and thereby energy
efficient operation. It is from this heating curve that the
heat pump's control computer determines the temper-
ature of the water to the heating system, supply temper-
ature, and therefore the indoor temperature. Select the
heating curve and read off how the supply temperature
changes at different outdoor temperatures here.
Curve coefficient
The slope of the heating curve indicates how many de-
grees the supply temperature is to be increased/reduced
when the outdoor temperature drops/increases. A
steeper slope means a higher supply temperature at a
certain outdoor temperature.
