A high difference indicates a low heating medium supply
and a low difference indicates a high heating medium
supply.
Read off what speed the heating medium pump should
have during manual operation from the diagrams below.

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
requires additional venting. Check the pressure in the
pressure expansion vessel (CM1) with the pressure
gauge (BP5). If the pressure drops, the system should
be replenished.

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 with the pressure gauge
(BP6). If the pressure drops, the system
should be replenished.
