The system can be equipped with a pulse extinguishing system for preventing
back fires by humidifying fuel with water when the auger surface temperature
increases. There are two humidification temperatures. Pulse extinguishing
utilises a Pt100 sensor, which measures the burner screw temperature, and a
magnetic valve, which controls the water supply to the burner screw.
NOTE! Water extinguishing system cannot be used with pellets.
When the burner screw surface temperature exceeds the Level 1
temperature -setting, the magnetic valve is controlled according to the Level
1 Extinguishing pulse and the Level1 Pause time -settings. Pulses are
continued until the temperature falls below the setting. If the temperature
keeps rising, the system will switch to the faster level 2 pulses. If the burner
screw surface temperature exceeds the
Temp. limit (back fire) -setting, the
burner will react similarly to when a back fire thermostat is set off.
SMS alarms can be activated with the LEVEL 1/2 ALARM NOT IN USE -
buttons.
