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.
Note
No special measures are required when shutting down
the system on a temporary basis.
Information on prolonged shutdown
■ As the heating circuit pumps no longer run for a lon-
ger period of time, these may seize.
■ After an extended shutdown, it may be necessary to
reset the date and time. See chapter "Setting the
time and date".
Shutdown
1. Note
Only disconnect the mains plug of the boiler for
maintenance and repair purposes.
■ Otherwise the Lambda probe will not be heated.
This can cause damage to the Lambda probe
during longer shutdown periods.
■ The boiler circuit pump is switched on briefly at
regular intervals.
2. Carry out the work in accordance with the "Inter-
vals" table in chapter "Overview of maintenance
and cleaning work"
3. If there is a risk of frost, drain the boiler. Observe
the instructions provided by your heating system
installer. Alternatively, you could ask them to add
antifreeze.
