Fans on, with ON/OFF regulation and with temperature/pressure transducer control, only when the
compressor is on (at least one relay is configured as fan control). When the compressor turns off the fans are
thermoregulated depending on the condensing temperature/pressure.
Par. FA01 = 3 / Par. FA02 = 0
Fans on, with ON/OFF continuos regulation and with temperature/pressure transducer control, only when the
compressor is on (at least one relay is configured as fan control). When the compressor turns off also the
fans are forced off.
Par. FA01 = 3 / Par. FA02 = 1
Fans on, with ON/OFF continuos regulation and with temperature/pressure transducer control, only when the
compressor is on (at least one relay is configured as fan control). When the compressor turns off the fans are
thermoregulated depending on the condensing temperature/pressure.
Par. FA01 = 4 / Par. FA02 = 0
Fans on, with proportional regulation (PWM, 4..20mA, 0.10V) and with temperature/pressure transducer
control, only when the compressor is on. When the compressor turns off also the fans are forced off.
Par. FA01 = 4 / Par. FA02 = 2
Fans on in proportional regulation (PWM, 4..20mA or 0..10V) according to condenser temperature/pressure
(only when the compressor is on).
When the compressor turns off the fans are thermoregulated depending on the condensing
temperature/pressure.

33.2 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).
FA04 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).
