FA6
Single or separate condensation fan
0= unique condensation (1 / 2 / 3 / 4)
1= separate condensers
2= unique by circuits (1 – 2) / (3 – 4)
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)
FA8
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.
FA9
Maximum operation speed of the chiller fans. This allows
you to set a maximum value for proportional fan regulation in chiller
mode. It is expressed as a percentage of the maximum voltage
allowed.
FA10
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.
FA11
Proportional regulation
Set maximum fan speed temperature/pressure in chiller mode. This
allows you to set the condensation temperature / pressure value in chiller
that corresponds to the maximum fan speed.
Step regulation
SET 2nd STEP This allows you to set the condensation temperature /
pressure value in chiller mode that corresponds to the operation in
ON of the relay output, configured as the 2nd condensation fan speed
step.
FA12
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).
FA13
Proportional regulation
Differential CUT- OFF in chiller. This allows you to set a temperature /
pressure differential in chiller mode to shut off the fan.
Step regulation
With Par. FA01=2/3 becomes the differential on the step itself of circuit 2
in chiller (see fans regulation graph).
FA14
Over ride CUT- OFF in chiller. This allows you to set a temperature /
pressure differential in chiller mode, where the fan maintains minimum
speed.
FA15
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.
FA16
Night function speed in chiller mode. This allows you to set a maximum
value for proportional regulation of the fans in chiller mode. It is
expressed as a percentage of the maximum voltage allowed.
FA17
Minimum fan speed in heat pump mode. This allows you to set a
minimum value for the proportional regulation of the fans in h.p. It is
expressed as a percentage of the maximum voltage allowed.
FA18
Maximum fan speed in heat pump mode. This allows you to set a
maximum value for the proportional regulation of the fans in h.p. It is
expressed as a percentage of the maximum voltage allowed.
