Maximum permitted pressure deviation
Defines the tolerance range for the specified pressure
setpoint in the FGR duct. If the actual value remains above
or below the pressure setpoint for the duration of the delay
time (parameter “Delay till warning”), a warning message
appears on the screen.
Delay till warning
Specifies how long the maximum permitted pressure
deviation must be exceeded in order to issue a warning.
FGR cleaning duration
Specifies the duration for the automatic cleaning of the
FGR duct in seconds.
FGR cleaning at CCT
Specifies the combustion chamber temperature, under
which the cleaning of the FGR duct is released when the
boiler is shut down.

Flue gas
Condenser
Condenser cleaning interval (heating hours)
Once the boiler has reached the specified operating hours
in “
Heating
” status, the condensing boiler heat
exchanger is rinsed.
On-time of spray valve. Overall cycle 20 sec
The entire washing process is set with the “
Condenser
cleaning duration
” parameter. The cleaning time is
regarded as the time in which the spray valve is active.
Pause times (spray valve off) are not included in the
cleaning time.
Example:
100% = spray valve active for the specified time
75% = spray valve active for 15 sec and 5 sec pause
Calorific value heat exchanger cleaning possible from
Time from which the washing process can be activated.
Calorific value heat exchanger cleaning possible until
Time to which the washing process can be activated.
