Threshold value OFF speed 1
in % [1...100]
Options:
1…10…100
This sets the threshold value at which fan speed 1 switches on. If the value in the control value communi-
cation object is greater than or equal to the parameterized threshold value, fan speed 1 switches on; oth-
erwise (if less) it switches off.
Threshold value speed 1 speed 2
in % [1...100]
Options:
1…30…100
This sets the threshold value at which switchover to fan speed 2 occurs. If the value in the control value
communication object is greater than or equal to the parameterized threshold value, switchover to fan
speed 2 occurs.
Threshold value speed 2 speed 3
in % [1...100]
Options:
1…70…100
This sets the threshold value at which switchover to fan speed 3 occurs. If the value in the control value
communication object is greater than or equal to the parameterized threshold value, switchover to fan
speed 3 occurs.
Hysteresis threshold
value in % +/- [0...20 %]
Options:
0…5…20
This sets a hysteresis 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
Threshold
value speed x
. The result is a new upper or lower threshold value.
Switch threshold top (switch on) = threshold value + hysteresis
Switch threshold bottom (switch off) = threshold value - hysteresis
