Vemer Chronos 230 Bianco User Manual page 24

In off mode the chronothermostat doesn't perform any regulation (*) but it continues to
display the day, the time and the measured temperature.
(*) When in heating / winter mode the chronothermostat maintains a minimum
temperature - Toff antifreeze temperature - to avoid the freezing of the
systems where the chronothermostat is installed.
Toff can have values between 1°C and 50°C or it can be completely shut
down; in this last case the saving of minimum temperature is not guaranteed.
The set default Toff is 6°C but it's possible to modify this value entering the
ADV menu (see "Antifreeze temperature" page 19).
To switch the chronothermostat off press the key
(field (9)).
To reactivate the regulation, switching back to the operating (automatic or manual)
which is before the switching off, press the key
