5.3.8 Filter
System menu
Boiler
Filter
Use filter?
Specifies whether a filter is used.
Minimum flue gas temperature for filter release
The filter is released from this temperature onwards.
Maximum flue gas temperature for filter release
The filter is released up to this temperature.
Max. runtime of filter bypass flap
If the filter bypass flap could not be moved within this time,
a fault is issued.
Max. runtime of filter cutoff flap
If the filter cutoff flap could not be moved within this time, a
fault is issued.
Filter cleaning timeout
If cleaning of the filter has not been reported as finished
within this time, it is assumed that the filter is faulty and the
filter is deactivated.
Filter rotary valve cycle
Cycle time of the rotary valve at the filter. Once this time
has elapsed, the rotary valve is switched on for a defined
amount of time.
Filter rotary valve runtime
Runtime of the rotary valve at the filter once a cycle has
been reached.
Filter rotary valve run-on bypass
If the filter is switched to bypass, the rotary valve is
activated for the time specified here to remove any
remaining dirt from the filter.
5.3.9 Burning chamber

Boiler
Burning chamber
Minimum CCT
Defines the minimum combustion chamber temperature in
“Heating” mode. The lower range of the output increase is
calculated in conjunction with the parameters “Power
increase from _K above minimum CCT” and “Min. output
at CC/FG-T min.”.
Power increase from__ K above minimum CCT
Defines the control band (“minimum CCT” + "0% CCT
signal at CCT” parameters), in which the power is
increased even before the minimum combustion chamber
temperature is reached, so that the temperature does not
fall below this level. The boiler output can be raised up to
max. “min. output at CC/FG-T min." parameter.
0% CCT signal at CCT
Together with the parameter “100% CCT signal at CCT",
this defines the control band for FGR and combustion
chamber cooling. From this temperature FGR and
combustion chamber cooling are controlled in a control
band from 0 - 100%, where 0% is this temperature and
100% is the maximum combustion chamber temperature.
100% CCT signal at CCT
Together with the parameter “0% CCT signal at CCT", this
defines the control band for FGR and combustion chamber
cooling. In this band the FGR und CC cooling are
controlled in a control band from 0 - 100%.
