FA33
Minimum fan speed in defrost mode. This allows you to set a
minimum value for proportional regulation of the fans in defrost
mode. It is expressed as a percentage of the maximum voltage
allowed.
FA34
Maximum fan speed in defrost mode. This allows you to set a
maximum value for proportional regulation of the fans in defrost
mode. It is expressed as a percentage of the maximum voltage
allowed.
FA35
Proportional regulation
Set maximum fan speed temperature/pressure in defrost mode. This
allows you to set the condensation temperature / pressure value in
defrost mode that corresponds to the minimum fan speed.
Step regulation
SET 4th STEP This allows you to set the condensation temperature /
pressure value in defrost mode that corresponds to operation in ON
of the relay output, configured as the 4th condensation fan speed
step.
FA36
Proportional regulation
Set minimum fan speed temperature/pressure in defrost mode. This
allows you to set the condensation temperature / pressure value in
defrost mode that corresponds to the maximum fan speed.
Step regulation
SET 3rd STEP This allows you to set the condensation temperature /
pressure value in defrost mode that corresponds to operation in ON
of the relay output, configured as the 3rd condensation fan speed
step.
FA37
Proportional regulation
Proportional band regulation of fans in defrost. 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 defrost mode (see fans regulation graph).
FA38
Proportional regulation
Differential CUT- OFF in defrost. This allows you to set a temperature /
pressure differential in defrost mode to shut off the fan.
Step regulation
With Par. FA01=2/3 becomes the differential on the step itself of circuit 2
in defrost mode (see fans regulation graph).
FA39
Over ride CUT- OFF in defrost. This allows you to set a temperature /
pressure differential in defrost where the fan maintains minimum speed.
FA40
Night function speed in defrost mode. This allows you to set a
maximum value for proportional regulation of the fans in defrost
mode. It is expressed as a percentage of the maximum voltage
allowed.
FA41
Third step setting in defrosting mode
SET 2nd STEP This allows you to set the condensation temperature /
pressure value in defrost mode that corresponds to relay output operation
in ON configured as the 2nd condensation fan speed step.
FA42
Fourth step setting in defrosting mode
SET 1st STEP This allows you to set the condensation temperature /
pressure value in defrost mode that corresponds to relay output operation
in ON configured as the 1st condensation fan speed step.
FA43
Differential on circ.3 steps in defrosting mode
With Par. FA01=2/3 becomes the differential on the step itself of circuit
3 defrost mode
FA44
Differential on circ.4 steps in defrosting mode
With Par. FA01=2/3 becomes the differential on the step itself of circuit
4 defrost mode
