36.2 Pwm Output For Fan Control
When the condenser fan is switched on it works at maximum speed for FA03 time, then it modulate
according to condenser pressure/temperature or evaporator pressure (heat pump mode).
F04 parameter allows to adapt the signal to the motor (current-voltage phase displacement of a line-powered
ac load).
If FA01=3, when the compressor starts-up and the proportional regulation requires to turn off the fan (cut-
off), if FA14
0 the fan is forced at the minimum speed for the time set in FA14 itself (if FA14=0 the function is
disabled).
36.3 Condensing Unit: Common Or Separate Condenser

FA05=0 Common condenser unit
FA05=1 Separate condenser units
If FA05= 0 the condenser fan of the circuit 1 and circuit 2 works in parallel:
CHILLER mode:
the regulation probe is the probe that has the higher value
HEAT PUMP mode:
the regulation probe is the probe that has the lower value
