switched on. To start the boiler - press
BURNER OFF? at any place on the screen.
The message: ACTIVE REGULATOR? appears.
Confirm the message. Boiler enters firing-up
stage. There is also another method of boiler
start-up. Press MENU button and find and
press button in pie menu.
To stop the boiler - press MENU button, and
find and press button in pie menu.
Note: regulator enters burning off phase.
Upon completion of burning off stage, the
message BURNER OFF appears.
8.3 Setting preset boiler temperature
Preset boiler temperature, just like the
preset mixer circuit temperature, can be set
in the menu:
Boiler settings
→
Preset boiler temp.
Mixer 1,2,3,4 settings
→
Preset mixer
temp.
Regardless of that, the preset boiler
temperature is automatically increased in
order to fill the hot utility water tank and
feed heating mixer cycles.
8.4 FIRING-UP
The FIRING-UP mode is used for automatic
firing-up of furnace in the boiler. All
parameters which influence the firing-up
process can be found in menu:
Service settings
→
Burner settings
→
Firing-up
If the firing-up failed, additional attepnts will
be
made. Consecutive attempts are
visualised by numbers next to the lighter
symbol .
After three unsuccessful attempts, an alarm
Failed firing-up attempt is reported. In such
case, the boiler operation is halted. Boiler
operation cannot be continued automatically
- service crew must intervene. After
removing causes of impossibility to fire-up,
the boiler must be restarted.
8.5 OPERATION
The fan operates continuously. Fuel feeder is
activated cyclically. A cycle consists of feeder
operation time and duration of feeding
interval
Parameters related with the Operation mode
are:
Feeder operation time and Fan output

8.6 Regulation mode
There are two regulation modes for
stabilizing the set temperature of the boiler:
Standard and FuzzyLogic
Boiler settings
→
Regulation mode
Operating in Standard Mode
When the boiler temperature reaches its set
value,
the regulator switches to
SUPERVISION mode.
The regulator has a boiler output modulation
mechanism allowing it to gradually reduce
the output as the boiler temperature nears
its set value
Three boiler output levels can be set:
maximum, medium, and minimum. Each
level can be additionally adjusted with
individual fuel feeding times and fan speeds,
affecting the actual output of the boiler. The
output level parameters are accessible
through the menu
Boiler Settings
→
Output modulation .
The regulator sets the current output of the
burner depending on the set temperature of
the boiler and H1 and H2 hysteresis settings
It is possible to set the H1 and H2 values to
modulate the output withouth the medium
power stage, ie. reducing output from 100%
to 30%, skipping the 50% output (right side
of the figure below)
