08.4 SAFETY THERMOSTAT WITH MANUAL RESET
Two safety thermostats are installed on the boiler to read pellet burner and circulating water temperature and trigger to turn off the boiler
when the relevant temperatures are faulty.
The safety thermostats can shutdown the boiler when, for example, the burner overheats, triggering the pellet thermostat, or when there
is no water circulation in the boiler, triggering the water temperature thermostat.
To restore normal boiler operations following forced shutdown by a thermostat, proceed as follows:
1.
Wait until the boiler is completely cold (on average 20
minutes);
2.
Unscrew the thermostat reset button lid on the back of the
boiler (see F
ig
. 1 , positions

or

);
3.
Press the button until you hear a CLICK;
4.
Refit the hood;
5.
Reset the alarm from the remote by pressing the button and
waiting for the OFF message;
6.
Start up again the boiler.
If the alarm persists, contact the specialised Technical Service
Center.
