FA 14 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.
