4.12.3. Lockout of the stove
The following things can cause the stove to lock out:
• Overheating of the structure and of the pellet hopper
• Overheating of the water in the boiler (T>85°C)
• High pressure in the outlet fumes (as read by the pressure
switch) and therefore possible obstruction of the smoke
discharge system or external back-pressure.
• Pressure in system less than or greater than the minimum or
maximum parameters of operation
The lockout is indicated by the LED (7) lighting up, accompanied by a
beep.
In this situation the shutdown cycle is automatically activated.
Once this process has started, any attempt to reset the system is
useless. The cause of the lockout is shown on the display (8).
4.12.3.1. Boiler bulb thermostat
The stove goes into a safety ALARM state called “ALAR SIC FAIL” due
to the water temperature being too high.
MANUAL RESET THERMOSTAT
With the stove cold
, in order to carry out the manual reset, you
must unscrew the cap of the thermostatic probe on the back and
press the red button to reset. You will hear a "click" of the
thermostat. Then put the protection cap back in place.
