Activating the regulator
After enabling power supply, the regulator
recalls its status at the moment of
disconnecting the power supply. If the
regulator was not active before, it will start
in the “stand-by” mode. In this mode, the
display is dimmed, and displays the current
time, weather sensor temperature and
information: “Boiler off”.
Fig. 5 Regulator screen with boiler off.
In this mode, the function of protecting the
pumps against stagnation is carried out by
activating the pumps periodically. Therefore,
it is recommended for the power supply to be
active during interruptions to boiler use, and
the regulator should be in the “stand-by”
mode described herein.
Fig. 6 Boiler activation screen.
It is possible to activate the boiler (press
encoder knob and select setting), or to set its
operation parameters (MENU button) without
the need for turning it on. After making sure
that there is fuel in the bin and that the bin
flap is closed, you can turn the boiler on.

Setting preset boiler 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 settings > Preset mixer temp.
Mixer 2 settings > Preset mixer temp.
Mixer 3 settings > Preset mixer temp.
Mixer 4 settings > Preset mixer 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 used for automatic firing-
up of furnace in the boiler.
Firing-up with manual control:
Boiler furnace can be fired up without the
use of a burner when the regulator is in
manual control mode. In such case boiler has
to be deactivated.
