MANUAL THERMOSTATS
The unit is equipped with one or more liquid expansion thermostats that perform the functions described
below:
MANUAL RESET LIMIT FUNCTION (sealed calibration 100°C):
It has the function of stopping the burner if the air is anomalously overheated. It shall be restored by pushing
the restore button, after removing the causes that have triggered it. This function is performed by a
thermostat, whose sensor is placed on the warm air outlet.
FAN FUNCTION (calibration 25-35°C):
It activates the fan max. 60 seconds after the burner has started and it stops it approx. 4 minutes after it has
stopped. Thus, it prevents unpleasantly cold air from being released in the room when the machine is activated
and the thermal energy accumulated by the heat exchanger can be disposed of and it is completely used
before the machine stops. This function is performed by a thermostat, whose sensor is placed on the warm
air outlet.
In some cases, the fan can be started also by a timer that is connected in parallel to the FAN thermostat.
