If the pellets don’t ignite, a new attempt for their burning will start
automatically.
If the sensor does not detect any flame during operation, the burner will stop and
a mode ALARM will start.
If more than few attempts for ignition appear unsuccessful, for example,
if the fuel ends, then the device turns off the normal algorithm and a
mode
ALARM
will start – the display light will start to blink - which is a signal for
the user that assistance is needed.
When the electrical supply stops and then restores, if burner was “on”, then it
starts automatically.
If the burner is not connected to a room thermostat, then the burner will turn on
and off upon reaching the preset minimum and maximum temperatures set by
the customer.
If the burner is connected to a room thermostat, then the burner will turn on after
room thermostat enable is received and minimal temperature in boiler is
reached.
After room thermostats disable command is given during operation the burner
will either stop or continue at low power for certain time – according parameter
settings.
GSM Tele control. The burner is supplied with tele-control input for connection
of external GSM tele-control module. The commands given can start or stop
operation of burner. The command is edge sensitive.
ADJUSTING THE BURNER
If the device does not work properly:
- check the pellets quality (they must have no dust). If the burner works
correctly, the pellets on the fire-grate should be as many as the holes on the grate
will be covered.
- check the flue gases temperature (175-240ºC). If it is too high, decrease the
pellets feeding. If the temperature is too low, increase the quantity of the air
supply.
Criterion for the proper burner operation is the flame color - IT SHOULD BE
YELLOW.
If the color is dark yellow, mixed with smoke, probably the quantity of the
supplied pellets is bigger than the necessary and it should be reduced.
Opening of the air valve affects on the combusting process, the purpose is calm,
stable combustion, without a residue (normally the valve is not tightly closed).
If the initial feeding dose for ignition is too big, it is possible burner “choke”,
i.e. it can not be started through activation of the thermostat once again.
