6.1.4. Fan Cycling
In minimum ventilation, the controller can
make a rotation of the fans selection between
consecutive cycles. This rotation allows run-
ning the fan motors evenly and regularly. In
order to use fan cycling, you must specify
how many fans must be activated simulta-
neously and specify after how many cycles
they must switch.
Here is an example of fan cycling with 4 fans.
In this example 2 fans are used simultane-
ously and a switch is made every 3 cycles:
Fan 1
Fan 2
Fan 3
Fan 4
