Switching OFF Vitodens with frost protection

Switch OFF the equipment if you don't want to use the boiler for a few days.

Heating system shutdown

Shut down your heating system completely, if it will not be needed for longer
periods of time (several months).
Before you switch your heating system OFF for longer periods, it would be advi-
sable to contact your local heating contractor. Your heating engineer will take
any necessary measures, e.g. for frost protection of the system or to preserve
the heating surfaces.
1. Close the main gas shut-off valve
and safeguard against
unauthorised reopening.
Turn rotary selector "tr" to "9".
Boiler frost protection is active.
2. Switch OFF the mains power.
Now the system is idle.
Please note that the system is no
longer frost protected.
