CHRONOS KEY Programmable Thermostat User Manual
OFF OPERATION
In off mode the instrument does not perform any regulation (*) but it continues to
display the day, the time and the measured temperature.
(*) In caso of heating / winter mode the instrument maintains a minimum
temperature - Toff antifreeze temperature - to avoid the freezing of the
systems where the instrument is installed.
Toff can have values between 1°C and 10°C or it can be completely
shut down: in this case the maintenance of minimum temperature is not
guaranteed. The set default Toff is 6°C but it is possible to modify this value
entering the ADV menu (see “Antifreeze temperature” page 19).
To switch the instrument off press the key
until the symbol
is displayed (field
(9)
).
To reactivate the regulation, turning back to the operating (automatic or manual) which
is before the switching off, press the key
for about 3 seconds.
