FA7
Pre ventilation before switching compressor ON. It allows you to set a start up
time for the fans at the maximum speed in chiller mode before the
compressor is switched on, in order to prepare for the sudden increase in
condensation temperature / pressure (that starting up the compressor
entails) and improving regulation. (only if FA01 = 4)

Minimum operation speed of the chiller fans. This allows
you to set a minimum value for proportional fan regulation in chiller
mode. It is expressed as a percentage of the maximum voltage
allowed.

Proportional regulation
Minimum fan speed Set temperature/pressure in chiller mode. This allows
you to set the condensation temperature / pressure value in
chiller
that
corresponds to the minimum fan speed.
Step regulation
SET 1st STEP
This allows you to set the condensation temperature
/ pressure value in chiller mode that corresponds to operation in ON
of the relay output, configured as the 1st condensation fan speed
step.

Proportional regulation
Proportional band regulation of fans in chiller mode This allows you to set
a temperature / pressure differential that corresponds to a variation from
minimum to maximum fan speed.
Step regulation
With Par. FA01=2/3 becomes the differential on the step itself of circuit 1
in chiller (see fans regulation graph).

CUT-OFF delay when fans are activated. This allows you to set a delay time
for the activation of the CUT - OFF function at fan start-up.
If at compressor start-up the proportional regulator requests the fans to be
shut off and FA15
≠
0, the fan will be forced at minimum speed for the set
time. If FA15=0, the function is not enabled.
