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.
-The auger introduces pellets more frequently into the burner.
-The combustion fan and exhaust fan increase in speed to speed up the combustion process.
-The ignition element remains on in this stage.
-At the end of this stage if the flue gas temperature is over a pre-defined temperature the process
continues to the next stage. (Run mode)
-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.
Run Mode
During run mode the combustion rates are pre-set for the 5 different power levels.
-On entering this phase the system starts at Power Level 1 and after defined time intervals increases
a Power Level each time until Power 5 is reached.
-The stove will continue to run at Power 5 until the water temperature reaches within 8°C of the set
point.
-The ignition element is off during this phase.
-The auger ON/OFF values are pre-set for each of the power levels.
-The circulation pump is activated by the controller once the water in the stove reaches 40°C. The
pump will turn off once the temperature drops to 38°C.
-If the unlikely event that the flue gas temperature decrease below pre-set low value for a period of
time then Er13 will appear to indicate that the light has gone out. This may be due to a lack of pellets
entering the combustion tube due to dust or poor quality pellets.
