mode gradually drops. Incorrect
settings may lead to boiler
overheating.
When the Supervision time expires, the
regulator switches to BURNING OFF mode,
unless the boiler temperature decreases and
the
boiler automatically switches to
OPERATION mode.
For the setting Supervision time = 0,
the
regulator skips the
SUPERVISION mode and enters the
BURNING OFF mode.
When the Supervision time = 255,
the regulator will work continuously
in SUPERVISION mode, until the
boiler temperature decreases and it
automatically
switches to
OPERATION mode.
8.8 BURNING OFF
The extinguishing process does not occur
when coal is the fuel of choice. When pellets
are the fuel, they are burned off for several
minutes (depending on the set time). After
BURNING OFF, the regulator switches to
STANDSTILL.
8.9 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).
8.10 Settings HUW preset temperature
The device controls temperature of the
domestic how water - HUW container,
provided that a HUW 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 HUW container,
parameter Off,
 set HUW priority, using the Priority
parameter - in this case, the CH pump is
deactivated to speed up filling of the HUW
container.
 set simultaneous operation of the CH and
HUW pump, using parameter No priority.
8.11 Disinfection of the HUW container
The regulator has a function of automatic,
periodic heating of HUW container to 70°C to
eliminate bacterial flora from the HUW
container.
The function is activated in the menu:
HUW settings
→
HUW disinfection
Keep the tenants informed of
activating the disinfection function
as there is risk of being burnt with
hot usable water.
The regulator increases the HUW container
temperature once a week, at 2:00 a.m.
Monday. After 10 minutes of maintaining the
temperature at 70°C, the HUW pump is
switched off and the boiler returns to normal
operation. Do not activate the disinfection
function when the HUW support is off.
8.12 Setting HUW preset temperaturę
Preset HUW temperature is defined by
parameter:
HUW settings
→
HUW preset temp.
HUW container hysteresis
When the temperature drops below the HUW
set temperature – HUW container hysteresis,
the HUW pump will start in order to supply the
HUW container.
In low hysteresis values, the HUW
pump will start faster when the HUW
temperature drops.
8.13 HUW circulation pump
The settings are located in:
HUW settings
→
Circulation pump night
time decrease
and
Service settings
→
CH and HUW settings
The time settings of the circulation pump are
analogous to the settings of night time
decrease. The pump will be off in the defined
time periods. At other times, the pump will be
on at Circulation pump operation time
between every Circulation pump standstill
time.
