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(SHUT DOWN) mode. When the boiler
water temperature drops below the desired setting it will result in switching of the
controller into „max 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 EXTINCTION (SHUT DOWN) 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.
EXTINCTION (SHUT DOWN).
When in this mode the controller turns off the fuel auger and engages the fan to
ensure complete fuel combustion and the burner cool down. Fan power when in
EXTINCTION (SHUT DOWN) mode is determined by the technician. When
EXTINCTION (SHUT DOWN) is finished the controller is switched into CLEANING,
STAND-BY or STOP mode, provided EXTINCTION (SHUT DOWN) followed as a
result of STOP button pressing.
CLEANING.
Automatic burner cleaning occurs after time set limit by programmer. In this mode
controller starts cleaning system for preset time. After this procedure controller
resets back to STANDBY 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 SHUT DOWN).
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
SHUT DOWN) 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.
