CONTROLLER START UP
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 container, and the hatch is
closed
–
the boiler can be switched on.

Settings preset temperature
Preset boiler temperature, just like the
preset mixer circuit temperature, can be set
in the menu (possible settings of these
temperatures are limited by the scope of
their
corresponding
regulator
service
parameters).
Boiler settings
→
Preset boiler temp.
Mixer 1-5 settings
→
Preset temp.
The value set as
Preset boiler temp.
is
ignored by the regulator if the preset boiler
temperature is controlled by weather sensor.
Regardless of that, the preset boiler
temperature is automatically increased in
order to fill the hot utility water tank and
feed heating mixer cycles.
8.5
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.

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.
