Check the safety valve (provided by customer) for the
hot water tank at regular intervals. Since an external
current anode is built in, the anode requires no
maintenance.

heating installation company. The company will conduct
all required maintenance at regular intervals.
Summer function
NOTICE.
The summer function can only be used in con-
junction with a geothermal heat exchanger (pro-
vided by the customer).
To prevent the supply air from being blown into the
rooms preheated during the hot season, you must
uncouple the heat exchanger from the air flow.
Switch off the unit and then open the upward
swivelling / hinged door of the ventilation and
domestic hot water module and remove the two
filters from the unit…
