FA03 C Fans max speed start time after ON (TRIAC). At each start,
irrespective of the condensing temperature / pressure the fan is
fed at maximum voltage for time FA03 after which the fan
continues to run at the speed set by the regulator.

FA06 C Pre-ventilation in chiller mode before compressor ON.
Used to set a run time of the fans at maximum speed in chiller
mode before compressor start, in order to anticipate the sudden
condensing temperature / pressure increase (resulting from
starting of the compressor) and improve temperature control.

Operation in chiller mode
FA07 C Minimum operating speed of fans in chiller mode.
Used to set a minimum value of the proportional control of the
fans in chiller mode.
Expressed as a percentage from 0 to 100% of the maximum
permitted voltage.
0 100 %
FA08 C Maximum operating speed of fans in chiller mode.
Used to set a maximum value of the proportional control of the
fans in chiller mode.
Expressed as a percentage from 0 to 100% of the maximum
permitted voltage.
0 100 %
FA09 C Proportional control:
Used to set the condensing temperature / pressure value in chiller
mode corresponding to the minimum fan speed.
Step control
1st STEP SET Used to set the condensing temperature / pressure
value in chiller mode to which operation in ON corresponds of the
relay output configured as 1st condensing fan speed step.

FA11 C Proportional control:
Fans control proportional band in chiller mode.
Used to set a temperature / pressure differential with a
corresponding change in fan speed from minimum to maximum.
Step control
With Par. FA01 = 2 or 3 this becomes the differential on the step
of circuit 1 in chiller mode.

CUT-OFF differential in chiller mode.
Used to set a temperature / pressure differential in chiller mode
for stopping of the fan.

With Par. FA01 = 2 or 3 this becomes the differential on the step
of circuit 2 in chiller mode.

FA14 C CUT-OFF delay time.
Used to set a time lag for activation of the CUT-OFF function at
starting of the fans.
If at the compressor start the proportional controller requests fan
cut-off and FA14 is different from 0, the fan will be forced to the
minimum speed for the set time.
If FA14=0 the function is not enabled.
