Automatic
operation
In off mode the instrument doesn't perform any regulation (*) but it continues to display
the day, the time and the measured temperature.
(*) In the case of heating/winter operation the instrument still maintains
a minimum temperature - Toff antifreeze temperature - to avoid the
freezing of the system and of the environment where the instrument is
installed.
Toff can have values between 1°C and 10°C or it can be completely
excluded; in this last case the maintainance of minimum temperature is
not guaranteed.
The default Toff is 6°C but it's possible to modify this value by accessing
the ADV menu (see "Antifreeze temperature" on page 29).
To switch the instrument off press the key
