Shutdown

Shutting down the heating system for an extended period
You can switch your heating system off if you do not
intend to use it. We recommend you contact your heat-
ing contractor before and after shutting down for longer
periods.
Your heating contractor can then take suitable steps,
such as frost protection for the system or heating sur-
face preservation, as required.
Shutdown
1. Note
Only disconnect the mains plug of the boiler for
maintenance and repair purposes.
■ The Lambda probe will otherwise not be heated
and could be damaged if the system is shut
down for a longer period.
The boiler circuit pump is switched on briefly at
■
regular intervals.
2. Carry out all tasks described in the overview of
chapter "Maintenance and repairs" on page 46.

observing the instructions issued by your heating
system installer or ask them to charge the system
with antifreeze.
