Switch OFF the boiler
Switch OFF the boiler with a long pushing of the button P2.
Led status when the boiler is switched OFF:
1.
The Extinguishing is signalled by the
blinking led L3
2.
The Extinguishing finished = OFF state is signalled by
the
fix led L3
When the boiler is switched OFF the fan continues running until the flue gas temperature falls
below the set trash hold and then the fan is turned off.
7.3 Operation Phases
Check Up
This stage allows for the cleaning of the boiler and burner before the ignition phase.
-The exhaust fan on the burner run at full power to eliminate any dust or smoke (in the event of a
hot restart) from the boiler.
-All the system sensors are checked for correct connections.
Pre-Heating
This stage brings the ignition element to the correct temperature before loading the burner with
pellets.
Pre-Load
A pre-defined starting dose of pellets is given into the burner by the auger.
Variable Ignition
This stage starts the ignition process.
-The heat from the ignition element is directed at the pellets by the fan which runs at a relatively
slow speed.
-At intervals the auger introduces more pellets once the flame has begun to establish.
-The flue gas temperature probe measures the temperature in the flue.
-At the end of this stage if the flue gas temperature is over a pre-defined temperature the process
continues to the next stage (Stabilisation)
-If this variable are not satisfied then this stage continues for another minutes (second ignition
attempt) and if the variable has not reached its value by the end of the second attempt,
EXTINGUISHING will occur and an Er12 (Failed Ignition) will be displayed on the screen.
Stabilisation
This stage develops the flame even further before allowing the system to enter RUN mode.
