Common Factory Settings for all types of fuel:
Equipment – Enable/disable the additional mechanisms and sensors of the burner's configuration and
set the polarity of the room thermostat's and the OD input's contacts:
Put check signs if the CH installation
has a room thermostat and its
contact is normally opened (NO)
Put a check sign if the burner
works with an external stop switch
connected to the OD input
with normally closed contact (NC)
General Settings – Set the internal auger motor's active time (Burner Feeder), the maximum allowed
set temperature for the boiler, the main auger's capacity and pending time for FC output, if necessary.
The internal auger motor always starts at the same time with the main auger and works for as long as it
is set in this menu. Its active time in seconds is:
where: T
is the internal auger motor's active time;
ia
T
is the fuel auger's active time (main auger).

Set this parameter to assure the
accuracy of the statistical information
for pellet consumption.
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
