If the condenser fan control is the triac output, when the regulation starts the
trigger output will drive the condenser fan at the maximum voltage for the time
FA 3 then, then the regulation will follow the temperature/pressure of the
probe.

CUT-OFF time delay. To set a time delay before activating the CUT-OFF
function after the fan start-up.
If after the compressor start-up the proportional regulator requires to turn off
the fan (cut-off) and FA140, the fan is on at the minimum speed for the time
set in this parameter. If FA14=0 the function is disabled.
