The fan control follows the given speed stages in the segments (through con-
trol contacts), taking into account the run-up and run-down times.
For 2-stage fans, the lower speed should be defined as stage 2, and the higher
speed as stage 3. The behavior will then be analog to that above (activate
stage 1 = switch off).
If several inputs have a simultaneous influence on the fan control function,
then the output is the highest stage for the fan speed.
If, for instance, stages 1 and 2 are simultaneously activated by inputs, then
only the output for stage 2 will be activated.
Description
The function is switched on or off here.
Defines the time for the fan to run at stage 2 when
the speed is increased.
Defines the time during which the fan is switched
off when the speed is reduced.
Signal to control the fan speed.
