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.
MAXIMUM POWER OPERATION MODE.
When in this mode the controller operates fuel auger and fan to ensure max. power
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
