Parameters should be selected in
such a way, that boiler
temperature would gradually
decrease when this mode is active.
Improper settings can cause the
boiler to overheat
Airflow in the SUPERVISION mode
operates with power set in the power
modulation parameter 30% Airflow
power.
The regulator returns to the OPERATION
mode automatically after boiler temperature
decreases by the value of boiler hysteresis in
relation to the preset temperature.
Maximum boiler operation time in the
supervision mode is defined by parameter:
... > Supervision > Supervision time
If after lapse of this time from the moment
of the regulator’s entering the supervision
mode, there is no need to reactivate the
boiler, the regulator will commence the
process of putting the boiler out.
8.9 BURNING OFF
In BURNING OFF mode, rest of pellets is
burnt and boiler is being prepared to stop or
shut-down.
All parameters, which affect burning-off
process are grouped in the menu:
SERVICE SETTINGS > BOILER SETTINGS
> BURNING OFF
Detailed description of burning-off cycle:
Fuel feeder stops,
Remaining fuel is burnt – the fan turns on
for the time set in Burning-off time with the
power set in the parameter of Air flush
intensity,
The furnace is cleaned - poker switches on.
Upon automatic burning-off, regulator enters
STANDSTILL mode.
8.10 STANDSTILL
In the STANDSTILL mode, the boiler is put
out and awaits signal to resume heating.
A signal to start heating can be:
decrease in preset boiler temperature
below the preset temperature minus the
value of boiler hysteresis (Boiler
hysteresis),
if the boiler is set to work with a buffer -
decrease in upper buffer temperature
below the preset value (Loading start
temperature).
8.11 Domestic how water settings
DHW
The device controls temperature of the
domestic how water - DHW – tank, provided
that a DHW temperature sensor is
connected. If the sensor is disconnected, an
information about lack thereof is displayed in
the main window. The parameter:
HUW settings > HUW pump mode allows
the user to:
disable filling of the tank, parameter
off,
set DHW priority, using the priority
parameter - in this case, the CH pump
is deactivated to speed up filling of
the DHW tank.
set simultaneous operation of the CH
and DHW pump, using parameter no
priority,
enable the summer function.
8.12 Setting preset DHW temperature
Preset DHW temperature is defined by
parameter:
DHW settings > Preset DHW temp.
8.13 DHW tank hysteresis
Below temperature DHW preset temp.
reduced by DHW tank hysteresis, the DHW
pump is activated in order to fill the DHW
tank.
When value of hysteresis is set too
low, the DHW pump will start faster
after decrease in DHW temperature.
8.14 Enabling the SUMMER function
In order to activate the SUMMER function,
which enables to load the DHW tank in the
summer, without the need for activating the
CH system and mixer cycles, set the
parameter DHW pump operation mode to
summer.
