Mechanical pressure switch
Feed Screw safety thermostat
Placed near the pellet hopper. It disconnects the electrical sup-
ply to the gear motor if the temperature detected is too high.
Water temperature detector
It reads the water temperature in the boiler and sends the circuit
board information for pump management and boiler power
modulation.
Water overheating safety thermostat
detects the water temperature in the thermo-stoves. If this is
electrical supply to the gear motor.
If the thermostat has been tripped it must be reset using the re-
set button behind the boiler after having removed the protective
cap.
Overpressure valve 3 bar

Manometer
It is positioned on the inside of the front part of the boiler
(opening the door) and shows the pressure of the water in the
boiler.
The recommended pressure is 1.5 bar when the boiler is on.
Drain tap
the water inside the boiler must be emptied.
