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). Operation and
pause time of the feeder in SUPERVISION
mode is set using following parameters:
Boiler output, Cycle time and Blow-in output.
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),
 by boiler operation configuration with the
buffer decrease of top buffer temperature
below
preset value (Loading start
temperature).
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". Can also press the
"TOUCH and PLAY" knob in the main window
and set the Boiler operation mode to Grate.
In the grate mode fuel feeder is turned off.
The combustion process is regulated by the
blow-in fan and exhaust fan. Fans power,
when working with grate, is set in the menu:
Boiler settings
→
Output modulation
→
Blow-in output – grate and Exhaust fan
- grate
The values of parameters such as: Preset
boiler temp., Boiler hysteresis and
Service settings
→
Burner settings
→
Fuel detection time
are individually adjusted for the "grate". This
allows you to define different properties of
boiler operation for operation modes "grate"
and "pellets".
When using the grid an alarm "No fuel" can
appear. This alarm occurs when a
temperature drops below the value of the
parameter:

period of 10 minutes there has been no
growth.
8.12 Burner cleaning
The controller enables for cleaning the
furnace
of ashes generated in the
combustion process. For this purpose, the
controller uses the work of the fan. In the
parameter Burner cleaning, in the menu
Boiler settings menu, set the max. time of
the burner operation without cleaning after
which the boiler will enter the BURNING OFF
mode, in which the mechanism for 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.
