8. Operation
8.10 SHUTDOWN mode
Burner is shutdown when the controller decides that the burner needs to be
shutdown, e.g. after reaching boiler temperature setpoint, after reaching DHW
temperature setpoint in SUMMER mode, after reaching the time set with Boiler
cleaning parameter. Shutdown mode continues until the remaining fuel is
completely burned. The burner will not be shutdown, if wood is selected as a
fuel. After SHUTDOWN, the controller switches to STAND-BY mode.
8.11 CLEANING mode
The controller cleans the burner using a fan and a linear actuator. After
switching to Shutdown mode, the controller activates the fan at 100% for 1
minute and checks the flame brightness. If the flame brightness is reduced, the
controller switches to Stand-by mode. If the flame brightness is not reduced, the
fan power is increased.
8.12 Ash pan counter settings
Ash pan filling level is expressed as a percentage, and is set as the quantity of
fuel burned with Ash pan cleaning parameter.
After the set quantity of fuel is burned, Ash pan full alarm is displayed and
the burner is stopped. To display ash pan information, set the ash pan reserve
with Ash pan reserve parameter. The message saying that ash pan cleaning is
required is displayed. The reserve time depends on the heat demand. DOOR
LIMIT SWITCH IS REQUIRED FOR CORRECT OPERATION.
During normal boiler operation, if the door is open for 30 seconds or longer, the
controller receives a signal and when the door is closed, the following message
is displayed: Ash pan cleaned?
Confirm to reset the ash pan counter or press X to continue with the previous
counter.
If ash pan is cleaned while the power is disconnected, there will be no reaction
to door opening.
Our new programme features an additional parameter: "ash pan cleaning"
reached by MENU-> boiler settings-> cleaning-> ash pan cleaning. It
causes zeroing of the ash pan counter.
8.13 STAND-BY mode
In STAND-BY mode, the burner is shutdown and awaits start signal e.g.:
•
boiler temperature setpoint decrease below temperature setpoint minus
boiler hysteresis value,
•
in buffer tank configuration, top buffer tank temperature decrease below
Buffer tank charging start temperature setpoint.
8.14 CHIMNEYSWEEP mode
The controller feature CHIMNEYSWEEP mode which enables all available heating
devices and starts the boiler until the power setpoint is reached:
CHIMNEYSWEEP mode > Boiler power setpoint
The function is used for testing and adjusting boiler operation.

8.15 Domestic hot water settings
The device controls the domestic hot water storage tank temperature, if the
DHW temperature sensor is installed. With the following parameter:
DHW settings > DHW pump operation mode user can:
•
deactivate storage tank charging; Off parameter,
•
set DHW priority with Priority - CH pump is disabled to speed up DHW
storage tank charging,
•
set simultaneous CH and DHW pump operation with No priority.
8.16 Disinfecting DHW storage tank
The controller allows automatic, periodical heating of DHW storage tank to 70°C
to remove the bacterial flora from the storage tank.
The controller displays the following message: „Disinfecting DHW" to indicate
increased DHW temperature.
PLEASE NOTIFY ALL USERS ON ACTIVE DISINFECTING FUNCTION
TO AVOID SCALDING WITH HOT WATER.
Once a week at 2 a.m. the controller increases DHW storage tank temperature to
70°C for 10 min and disables DHW pump. After 10 minutes, the boiler restores
its normal operation mode. Do not use the disinfection function when DHW is
not use.
8.17 Setting DHW temperature setpoint
DHW temperature setpoint is set in:
DHW settings > DHW temperature setpoint
Below DHW temperature setpoint - DHW storage tank hysteresis, DHW pump is
activated to charge the DHW storage tank.
AT LOW HYSTERESIS SETTING, DHW PUMP WILL ACTIVATE QUICKER
AFTER THE DHW TEMPERATURE DECREASES.
Parameters related to circulation pump operation are only available upon
installation of the B module.
The settings can be modified in::
DHW settings > Circulation pump nighttime setback and
Service settings > CH and DHW settings
Time settings of the circulation pump control are the same as the nighttime
setback settings. The circulation pump is disabled at defined intervals, and then
enabled for the time set with Circulation pump operation time every Circulation
pump idle time.
DHW temperature threshold, below which the circulation pump is enabled to
force the flow may also be set.
