V.e) Operation settings
This submenu is available only when Standard operation algorithm is selected.
Tap on Operation settings icon in order to adjust CH boiler operation settings.
V.e.1) Operation algorithm
In this submenu the user may choose between Standard operation algorithm and Modulation.
Once Modulation is selected, Operation settings submenu changes into Modulation settings
submenu.
V.e.2) Feeding pause
This option is used to set the pause time of the feeder. The length of the pause should be
adjusted to the type of fuel used.
Incorrect pause time may result in inefficient operation of the CH boiler, i.e. unburnt coal left or
failure to reach the pre-set temperature of the CH boiler. Appropriate pause time ensures efficient
operation of the CH boiler.
V.e.3) Blow force
This function is used to control the fan speed. The setting range is 1-100%. The higher the gear
is, the faster the fan works. 1% is the minimum fan speed whereas 100% is the maximum fan
speed.
V.e.4) Operation in sustain mode
This option is used to set the operation time of the feeder and the fan when the CH boiler operates
in sustain mode (i.e. above the pre-set temperature).
V.e.5) Pause in sustain mode
This option is used to set the feeder pause time when the CH boiler operates in sustain mode
(operating above the pre-set temperature)
WARNING:
Incorrect pause time may result in further temperature increase! The user should make
sure that the pause time in sustain mode is not too short.
V.e.6) Fan in sustain mode
This option is used to set the fan operation and pause time in sustain mode.
V.f) Modulation settings
This submenu is available only when Modulation operation algorithm is selected.
V.f.1) Operation algorithm
In this submenu the user may select Modulation as the CH boiler operation mode. Then, Operation
settings submenu changes into Modulation settings submenu.
V.f.2) Modulation 30%, Modulation 60%, Modulation 100%
Tap on Modulation settings in order to adjust CH boiler operation settings.
The user may adjust operation time, feeder activation frequency and blow force for the following
modulations stages.
In the case of 100% and 60% modulation, the user also sets Range from set temp. parameter
which defines the moment of switching to another modulations stage.
Example:
Pre-set CH boiler temperature: 55⁰C
Range from set temp. for 100% modulation: 20⁰C
Range from set temp. for 60% modulation : 10⁰C
