Threshold value OFF <-> speed 1
in % [1...100]
Options:
1...10...100
Here the threshold value is set at which switch on of fan speed 1 occurs.
If the value in the control value communication object is greater than or
equal to the parameterised threshold value, fan speed 1 is switched on.
If the value is less, than it is switched off.
Threshold value speed 1 <-> speed 2
in % [1...100]
Options:
1...30...100
Here the threshold value at which switch over to fan speed 2 occurs is set.
If the value in the control value communication object is greater than the
parameterised threshold value, switch over to fan speed 2 occurs.
Threshold value speed 2 <-> speed 3
in % [1...100]
Options:
1...70...100
Here the threshold value at which switch over to fan speed 3 occurs is set.
If the value in the communication object Control value HEATING or Control
value COOLING is greater than the parameterised threshold value, switch
over to fan speed 3 occurs.
Hysteresis threshold
value in % +/- [0...20 %]
Options:
0...5...20
Here a hysteresis is set at which switchover to the next fan speed occurs.
The hysteresis applies for all three threshold values.
The setting 0 causes immediate switching without hysteresis.
The entered percentage value is directly added to or subtracted from the
percentage value of the Fan speed x threshold value. The result equals
the new upper or lower threshold.
Switch threshold top (switch on) = threshold value + hysteresis
Switch threshold bottom (switch off) = threshold value + hysteresis
