auger channel until temperature drops.
ALARMS Safety and temperatures sensors failure alarms.
STOP.
Controller maintains central heating and domestic water pumps operation only to
protect the boiler against overheating and auger channel ignition. Room thermostat
contacts closing(call for heat) and domestic water temperature drop do not result in
any action. Pressing START button (10) will result in switching the controller to
STANDBY mode.
STANDBY.
In this mode controller does not carry out any additional operation, until room
thermostat contacts close (call for heat) or domestic water temperature drop, the
boiler operation will focus on maintenance of temperature according to thermostat
setting programmed with the knob. If preheating of domestic water tank is necessary
and the desired boiler temperature setting is higher from domestic water
temperature setting the controller will follow higher setting. Pressing the STOP
button (9) will result in switching to STOP mode.
IGNITION.
Boiler controller is switched into IGNITION mode if demand for heat follows, and if
the controller did not detect the flame. During ignition the controller activates fan,
auger and igniter. Fuel and air feeding rate is adjusted by the technician. IGNITION

mode follows till flame is detected. If the flame is not detected within the specified
time, the controller activates „Out of fuel alarm”. Pressing STOP button, exceeding
time limit for cleaning, thermostat contacts opening or if water temperature in
domestic water tank is obtained during operation in IGNITION mode will result in
switching of the controller into the POSTCOMBUSTION mode.
KINDLE FIRE STABILIZE.
After the flame has been detected the boiler burner is switched into the KINDLE
FIRE STABILIZE mode. While in the mode the fan operates with the maximum
power. The fuel dose given by the auger is the same as while at work with the
minimum power. Additionally, depending on the service settings, the fuel dose may
be increased gradually. KINDLE FIRE STABILIZE option is being carried out for the
period of time set in the service settings or till the moment the boiler reaches the
programmed temperature. Pressing STOP button, exceeding time limit for cleaning,
thermostat contacts opening or if water temperature in domestic water tank is
obtained during operation in the KINDLE FIRE STABILIZE mode will result in
switching of the controller into the POSTCOMBUSTION mode.
CAUTION! The KINDLE FIRE STABILIZE mode can be turned off by the technical
staff. In such case the controller is switched into the work with the maximum power
after the ignition cycle has been finished.

of the boiler. Fuel and air feeding rate is adjusted by the technician. Pressing STOP
button, exceeding time limit for cleaning, thermostat contacts opening or if water
temperature in domestic water tank is obtained during operation in MAXIMUM
POWER mode will result in switching of the controller into EXTINCTION
(SHUTDOWN) mode.
MODULATED POWER OPERATION MODE.
Depending on desired parameters the controller may gradually reduce fuel and air
rate feeding to reduce burner power, as much as boiler water temperature
corresponds to the programmed setting. Pressing STOP button, exceeding time limit
for cleaning, thermostat contacts opening or if water temperature in domestic water
tank is obtained during operation in MODULATED POWER mode will result in
switching of the controller into POSTCOMBUSTION mode.
MINIMUM POWER OPERATION MODE.
When in this mode the controller operates fuel feeding and fan operation to maintain
firing to ensure the minimum fuel consumption. Fuel and air feeding rate is adjusted
by the technician. If in spite of boiler minimum power, increase temperature follows
of water temperature in relation to the top hysteresis parameter setting, the controller
will be switched into EXTINCTION (SHUTDOWN) mode. When the boiler water
temperature drops below the desired setting it will result in switching of the controller
into „Maximum power operation mode”. Pressing STOP button, exceeding time limit
for cleaning, thermostat contacts opening or if water temperature in domestic water

tank is obtained during operation in MINIMUM POWER mode will result in switching
of the controller into POSTCOMBUSTION mode.
SCAVENGE (AIR PURGING).
During the operation with minimum power output, the controller will activate flue
scavenge (purging) to ensure removal of accumulated gases. Scavenge (purging) is
provided with temporary fan operation in higher speed.
POSTCOMBUSTION.
In the mode the auger is turned off by the regulator. The fan power is not altered (it
works with same speed as when the POSTCOMBUSTION mode was turned off).
The POSTCOMBUSTION prolongs till the moment the flame dies down, after which
the regulator is switched into the EXTINCTION mode.
EXTINCTION (SHUTDOWN).
In this mode the fan power is changed to the value programmed by the technical
staff to ensure complete fuel combustion and the burner cool down. When
EXTINCTION (SHUTDOWN) is finished the controller is switched into CLEANING,
STANDBY or STOP mode, provided POSTCOMBUSTION, EXTINCTION
(SHUTDOWN) followed as a result of STOP button pressing.
CLEANING.
The automatic furnace cleaning is carried out if the extinction time has been
determined by the technician or the burner has been operating long enough. In the
mode, the cleaning mechanism is activated for the period preprogrammed by the
technician. If the STOP button has been pressed during the cleaning, the controller
will enter either the STANDBY or STOP mode.
AUGER (MANUAL) REFILLING.
User may activate auger manual refilling function. When device is in STOP mode,
press START and hold button for 5 seconds to start refilling. Refilling follows
according to the time programmed by the technician or until it is manually turned off
with STOP button.
AUGER EXTINCTION (EMERGENCY SHUTDOWN).
If the auger is equipped with a temperature sensor, a temperature increase above
the range programmed by the technician, it will result in activation of auger ignition
alarm. The controller turns off the fan and auger. If the burner is equipped with the
stoker, the device is switched additionally into AUGER EXTINCTION (EMERGENCY
SHUTDOWN) mode. During shut down the stoker is engaged for the time needed to
remove the ignited fuel from the stoker. In addition if the burner has cleaning
mechanism, the controller will activate the cleaning cycle and remove fuel from the
burner.

Stoker work mode - this parameter specifies work mode of the stoker:
„OFF” - the burner without the stoker.
„CYCL.” - stoker is switched on periodically, regardless of the auger. Work
and pause time of the stoker is determined with particular settings.
„AUTO” - operation mode when the stoke is switched on along with the
auger and is switched off with a delay defined with „Stoker extra work time” setting.

Auger ignition test - this parameter provides functionalities of „X” emergency input.
If „NO” setting was selected then „X” input will be used for connection of e.g. auger
flap opening contact sensor or the contact informing on operation of auger motor
overload switch. If „YES” setting was selected then „X” input will be used for
connection of auger temperature sensor used for ignition detection.
