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
STAND-BY mode.
STAND-BY.
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 EXTINCTION (SHUT DOWN) mode.
MAX. 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 MAX.
POWER mode will result in switching of the controller into EXTINCTION (SHUT
DOWN) 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 EXTINCTION (SHUT DOWN) mode.
