into the SUPERVISION mode, and to supply
as much heat, as the CH system requires at
the time.
In the SUPERVISION mode, the regulator
supervises the furnace, so that it would not
go out. For this purpose, the airflow and the
feeder are activated only for a while, rarer
than in the OPERATION mode. Without
causing further temperature increase.
The airflow does not work continuously,
it is activated cyclically together with
the fuel feeder, which prevents the
flame from going out during boiler
standstill
.
Fig. 12 View of main window in the
SUPERVISION mode.
All parameters regarding boiler setup in the
SUPERVISION can be found in the menu:
Service settings > Boiler settings >
Supervision
Parameters of the SUPERVISION mode
should be set in accordance with boiler
manufacturer’s
recommendations.
They
should be chosen in such a way, that the
furnace did not go out during boiler standstill
(at the same time, it should not fire up too
intensively, as this will trigger increase in the
boiler temperature). Duration of the feeder
operation and interval in the SUPERVISION
mode are set using parameters:
... > Supervision > Supervision feeding
time
... > Supervision > Supervision feeder
interval
The time of extending the airflow in order to
ignite fuel after feeding thereof is set in:
... > Supervision >Airflow operation
extend.
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.

PUTTING OUT
In the PUTTING OUT mode, remains of the
pellet are burnt out and the boiler is
prepared for standstill or deactivation.
All parameters which influence the process of
putting out can be found in menu:
Service settings >
Boiler settings > Putting out
Detailed description of the putting out cycle:
Feeder operation is halted,
Fuel remains are burnt out - Fan is
activated for
Putting
out time
and with
power specified by parameter
Putting
out
airflow
,
The furnace is cleared - the poker is
activated.
After automatic putting out, the regulator
switches into STANDSTILL mode.
