3.3 TWIN THERMOSTAT OPERATION
The thermostat’s sensor is placed on the suction vent. It can start and stop the ventilation system (FAN function),
and regulates the overheating alarm mechanism (LIMIT function) when it is available.
3.3.1 FAN FUNCTION
When the ambient temperature near the sensor reaches the value set on the twin thermostat’s board (40°C), an
electric contact in the thermostat will be closed, and the ventilation system will activate.
When the ambient temperature near the sensor drops lower than the value set on the twin thermostat’s board
(30°C) an electric contact in the thermostat will be opened, and the ventilation system will stop.
3.3.2 LIMIT FUNCTION
When the air in proximity of the sensor is overheated due to an anomaly, and the temperature reaches the value
set on the twin thermostat’s board (100°C), an electric contact in the thermostat will be closed, and the alarm
will activate.
3.3.3 PLUGGING AND CALIBRATION
The warm air generator’s wirings are already plugged, and the twin thermostat is already calibrated. Should
you need to perform those operations again (in case of maintenance, checkups, or replacements), please follow
the instructions below (fig. 15):
Legend:
1. Wirings for FAN function.
2. Twin Thermostat’s board.
3. Fastening holes.
4. Ventilation system’s stop temperature indicator.
5. Ventilation system’s start temperature indicator.
6. LIMIT function’s activation temperature indicator.
7. Holes for wires block. By inserting the tip of a screwdri-
ver in this hole, the clamp will be blocked, and it will
be possible to insert a wire. Removing the tip of the
screwdriver will automatically block the wire inside
the clamp.
WARNING! Make sure the wire is tightly
blocked inside the clamp by gently pulling
it.

9. Metal bridge10.
White button for automatic (raised) or manual (pressed) ventilation.
IMPORTANT!
The metal bridge (9) must be removed in all models.
When adjusting values (4) (5) (6) do not turn the board (2), or the twin thermostat will be
damaged.
