Switching OFF Vitodens with Frost Protection

Shutting Down the Heating System

Switch OFF the equipment if you do not wish to use your
heating system for a few days.
Turn selector dial "tr" to "0".
Boiler frost protection is active.
Frost protection
Frost protection is continuously active. The burner is
switched ON when the boiler water temperature reaches
41° F (5° C) and is switched OFF again when the boiler
water temperature reaches at least 59° F (15° C) but not
more than 68° F (20° C).
Shut down your heating system completely, if it is not
needed for longer periods of time (several months).
Before you switch your heating system OFF for longer
periods, it is advisable to contact your local heating
contractor. Your heating professional will take any
necessary measures, e.g. for freeze protection of the
system or to protect the heat emitter surfaces, e.g.
radiators etc.
1. Close gas shutoff valve and secure against
unintentional opening.
2. Switch OFF line voltage (e.g. at separate fuse/circuit
breaker).
The power supply to the system is now switched off.
IMPORTANT
At this point the boiler and the system are no longer
protected from freezing.
