Hysteresis threshold
value in % +/- [0...20 %]
Options:
0…5…20
This sets a hysteresis at which switchover to the next fan speed occurs.
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
Example: Single-speed fan control with hysteresis
Using hysteresis avoids continual switching caused by fluctuating input signals around the threshold value.
