8.7 SUPERVISION
SUPERVISION mode is applicable either in
regulation in STANDARD and Fuzzy Logic
mode.
The controller switches into SUPERVISION
mode
automatically without user’s
intervention: - in Standard regulation mode
–
after reaching the boiler preset
temperature, - in Fuzzy Logic steering – after
exceeding boiler preset temperature by 5
degrees C.
In SUPERVISION mode the controller
oversees the furnace, keeping it from
burning off. When activated, this mode can
minimise the frequency of firing up and then
burning off. This mode is especially useful in
hydraulic systems without a thermal buffer.
To do so, the burner operates with very low
power, what together with properly adjusted
parameters do not cause further increase in
temperature.
Burner’s power in
SUPERVISION mode and other parameters
of Supervision are grouped in menu:

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). Operation and
pause time of the feeder in SUPERVISION
mode is set using following parameters:
Feeding time SUPERVISION , Period time
SUPERVISION and Air flush intensity
SUPERVISION .
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 parameter
Supervision time . If after this time (in
Supervision mode)
there is no need to restart the boiler boiler
controller will go in STOP mode.
For setting Supervision time = 0 the
controller omits SUPERVISION mode
and goes directly to STOP.
8.8 STOP
In STOP mode the boiler 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 (
Temperature when
start buffer feeding ).
8.9 PAUSE
PAUSE mode is induced manually by pressing
the encoder. Be sure to select "PAUSE
MODE". In this mode, the burner is stopped.
Pumps are not Stoppel. To turn off the
"PAUSE Mode", press the dial and select
"OPERATION".
Note: The "PAUSE MODE" can also
be
invoked automatically by
opening a valve in the boiler
smoke conduit and the lack of fuel.
The controller automatically comes
out of "PAUSE MODE" when causes
are removed (fill the fuel, close the
damper).
8.10 HOT WATER SETTINGS
The controller regulates temperature of the
silo of Hot Water HW, providing that the
temperature sensor is connected. When the
sensor is disconnected – the information
about it is displayed in the main window. By
selecting:
Menu
→
HUW settings
→
HUW Pump
mode the user is able to:
 Deactivate feeding the silo, parameter
Deactivated ,
 Setting HW priority, by parameter
Priority – then CH pump is
deactivated to feed the HW boiler
quicker,
 Set simultaneous operation of CH and
HW pump with the parameter No
priority ,
 Activate function Summer .
