NOTE 2
For best comfort, the chronothermostat
makes up for the unavoidable slowness in
heating the room.
When a decrease in temperature is
detected, the heating system is turned on
before temperature drops below the set
level.
For this reason, it is possible that the
heating system is turned on, for short
periods of time, even if the measured tem-
perature is higher than the set one.
