Check the instructions how to
calibrate the auger motor on page 20.
Instead of powerful cleaning fan, the FC output can control a mechanical cleaning actuator. During the
cleaning procedures where the FC output is active, the actuator moves in one direction to push out the
ashes. After the procedure is over the controller cuts the power supply to the FC output and the
actuator needs time to get back to its initial position. Put a check sign on the parameter FC output and
after every cleaning procedure the controller will wait for the actuator to get back for as long as the
output has been supplied with power during the procedure.
Flame Detection – Set the level of illumination measured by the photo sensor and for how long the
controller has to wait until the ignition and extinction are successful.
The ignition is successful, if the
photo sensor measures more
than 100 for more than 20 seconds
Power Modulation – Set the difference between the set temperature and the boiler's temperature for
each power level. When it is more than the value for P3, the burner works on 3

power level. When it

When the difference is between the values for P1 and P2, the burner works on 1

it's less than the value for P1, the burner woks on Suspend power level. While on Suspend, if the
difference between the set temperature and the boiler's temperature increases enough for 1

level, the burner automatically switches to it. If the difference doesn't increase, the burner works on
Suspend power level for as long as it is set in the parameter Duration [min]. While on Suspend, if the
temperature of the boiler is still increasing, when it gets higher than the set temperature with as many
degrees as set in the parameter Overheating, the burner will turn off immediately.
