Flue gas
Maximum heating up time, during which HEATING status
must be reached
If the criteria for the “Heating” status is not reached after a
specified time, it switches to “Heating” status regardless.
When the flue gas temperatures rises and the residual
oxygen content falls, the “Heating” status remains active. If
the criteria for “Heating” status is not reached within 5
mins, the boiler switches to “Off” status.
Minimum flue gas temperature
Lowest operation point of flue gas temperature for
continuous operation.
Minimum flue gas temperature in pellets mode
Lowest operation point of flue gas temperature in pellet
mode for continuous operation.
Maximum flue gas temperature
Highest operation point of flue gas temperature for
continuous operation.
Start increase of flue gas temperature
The flue gas setpoint rises by the specified value set here
during “Heating up” status.
Boiler output at flue gas temperature of 20°C
Lower point of the start ramp of boiler controller at system
startup.
100% boiler output from a flue gas temperature of
Upper point of the start ramp of boiler controller. If the flue
gas temperature reaches the value set here, the fuel
output should reach 100%.
Minimum difference between flue gas temperature and
boiler temperature in HEATING
As a condition for the “Heating” operating status, the
difference between the current flue gas temperature and
the current boiler temperature must at least exceed the
value set here.
Flue gas - Flue gas difference for start process
When the boiler controller changes to “Pre-heating” status
the current value of the flue gas temperature is stored.
When the flue gas temperature rises by the specified value
set here during “Pre-heating” or “Ignition” status, the boiler
controller switches to “Heating” status.
Safety time
If the condition “Minimum difference between flue gas- and
boiler temperature in HEATING” is not fulfilled for the set
duration, the message “Safety time expired, flue gas
temperature too low for too long” appears on the display.
Flue gas temperature, below which boiler switches to
SHUTDOWN status
If the flue gas temperature is below this value for the
duration of the
“Maximum heating up time, during
which HEATING status must be reached”
, the
boiler switches to “Off” status.
Activating the note to close the door
▪ YES: If the criteria for “Heating” status is reached when
heating up, the note “Close the door!” appears on the
display.
▪ NO: The “Close the door!” message is not displayed
after reaching the criteria for the “Heating” status.
Increase of flue gas temperature for note to close the door
appears
When the flue gas temperature rises by this value in
“Heating up” status, the message “Close the door!”
appears on the display.
Residual O2 content under which the note to close the
door appears
When the residual oxygen content falls below this value in
“Heating up” status, the message “Close the door!”
appears on the display.
