After connecting the power the controller
shows the settings put before connecting the
electricity. If the controller has not operated
before – it will start up in „stand by” mode.
In this mode the screen is dimmed, actual
time and information: Boiler on is displayed.
In this mode protecting pumps against going
stale function is in operation. It is executed
by temporary switching them on. Therefore it
is advised to keep the electrical power to the
controller on when the boiler is not in use.
And the controller should be in “stand by”
mode. It is possible to start up the boiler
(pressing the encoder knob and selecting
„switch on”) or setting parameters of its
operation (MENU button) without connecting
it to the electrical power. After making sure
that fuel is in the silo, and the hatch is closed
– the boiler can be switched on.
8.4 FIRING UP
FIRING UP mode is for automatic firing up of
furnace in boiler. Total time of firing up
process is depended on controller’s settings
(feeder operation time, heater operation
time, etc.) and on boiler’s condition before
firing up. Parameters influencing firing up
process are in the menu:
Service settings →Boiler settings→
Firing up
In case of failed attempt of firing up the
furnace, another attempts are taken during
which amount of fuel (feeding time) is
reduced to 10% of first attempt’s dose.
Pic. 4 Signaling FIRING UP mode and number of attempt
After three failed firing up attempts an alarm
Failed firing up attempt is reported. Boiler’s
operation is then stopped. It is not possible
to automatically continue boiler’s operation.
Service intervention is required. After finding
and solving the cause of firing up failure the
boiler should be fired up again.
8.5 WORK
Pic. 5 Main window view while operating.
The fan operates constantly – see Pic. 6. Fuel
feeder is engaged periodically. One period
consists of feeder operating time and pause
in feeding time.

There are two regulation modes responsible
for stabilization of boiler preset temperature:
Standard and Fuzzy Logic:
Boiler settings → Regulation mode
Standard mode operation
If the boiler’s temperature reach preset one
then the controller switches to SUPERVISION
mode.
Controller is equipped with boiler’s power
modulation mechanism – which allows for
gradual power reduction when approaching
the preset temperature.
There are three power levels:
- Maximal power
- Medium power
- Minimum power
Values of the individual power levels can be
set in the below menu:
