further increase in temperature. Burner’s
power in SUPERVISION mode and other
parameters of Supervision are grouped in the
menu:
Service settings → Burner settings →
Supervision
Parameters of SUPERVISION mode are to be
set in accordance to burner/boiler producer’s
recommendations. They should be so chosen
to prevent the furnace from burning off
during boiler’s pauses (the furnace should
not at the same fire up to too high a
temperature, because it will cause too high a
temperature of the boiler).
The parameters in this mode must
be so chosen as to make the boiler
temperature gradually decreasing.
Incorrect settings can cause boiler
overheating.
Maximum time of boiler’s operating in
supervision mode is defined in service
parameter Supervision time. If after this time
(in Supervision mode) there is no need to
restart the boiler then the controller starts
the process of boiler’s burning off.
For setting Supervision time = 0 the
controller omits SUPERVISION mode
and goes directly to BURNING OFF.
8.9 BURNING OFF mode
In BURNING OFF mode the leftovers of pellet
are burnt and the boiler is prepared to pause
or deactivation. All the parameters
influencing burning off process are grouped
in the menu:
Service settings →
Burner settings → Burning off
The controller stops feeding fuel and makes
periodical blowings to burn off remnants of
fuel. After decrease of flame brightness or
maximum time of burning off expiration the
controller turns into STOP mode.
8.10 STOP mode
In the STOP mode the boiler is being burnt
off and awaits the signal to start operation.
The following can be a signal to start
operation decrease of preset boiler
temperature below preset temperature
diminished by boiler hysteresis (Boiler
hysteresis).
8.11 GRATE
Some boilers have an additional grate to
burn other fuels such as wood waste, etc. To
activate the grid, move the parameters
available in the menu:
Boiler settings → Boiler oper. Mode from
Pellet to Grate. In the grate mode fuel feeder
is turned off. The combustion process is
regulated by the blow-in fan. Fan power,
when working with grate, is set in the menu:
Boiler settings → Output modulation →
Blow-in output – grate
The values of parameters such as: Preset
boiler temp., Boiler hysteresis, Fuel detection
time are individually adjusted for the Grate.
This allows to define different properties of
boiler operation for operation modes Grate
and Pellets.
8.12 Burner cleaning
The controller is used for cleaning the
furnace of ashes generated in the
combustion process. For this purpose, the
controller uses the work of the blow-in fan
with power set in the Cleaning intensity
parameter, in the menu Boiler settings, set
the time of the burner operation without
cleaning after which the boiler will enter the
BURNING OFF mode, in which the
mechanism for rotary cleaning of the burner
will be started and then firing-up the burner.
Purification of the furnace is made during
FIRING UP and BURNING OFF. Additional
parameters responsible for cleaning are in
the menu:
Service settings → Burner settings →
Cleaning
8.13 HUW settings
The controller regulates temperature of the
HUW tank, providing that the temperature
sensor is connected. When the sensor is
disconnected – the information about it is
displayed in the main window. By selecting:
HUW settings → HUW Pump mode the
user is able to:
• deactivate feeding the silo, parameter
Off,
• setting HUW priority, by parameter
Priority – then CH pump is deactivated to
feed the HUW boiler quicker,
