Proportional regulation
Condensing pressure/temperature value corresponding to the maximum
outdoor fan speed defined at FA08
Step regulation

nd
STEP Set: Condensing pressure/temperature value corresponding to the
activation of the 2
nd
outdoor fan step.
Proportional regulation
Fans regulation proportional band in cooling mode
Defines the condensing pressure proportional regulation band corresponding
to a variation from the minimum outdoor fan speed (FA07) to the night outdoor
fan speed (FA15).
Step regulation
Condensing pressure/temperature differential between activation and
deactivation of the outdoor fan steps (ciruits 1/2)..
Proportional regulation
CUT-OFF differential in cooling mode. Defines a condensing
pressure/temperature differential for fan switch-off.
Step regulation
Condensing pressure/temperature differential between activation and
deactivation of the outdoor fan steps (ciruits 3/4).
CUT-OFF over ride. Defines the pressure/temperature differential in which the
fan remains at minimum speed.
CUT – OFF minimum working time. Defines the minimum working time at
minimum speed at compressor start regardless the condensing pressure
level.
FA14=0 means function is not enabled.
Night function speed. Defines the maximum fan speed for the proportional
regulation in cooling mode. It is expressed as percentage (100%=10V)
Outdoor fans working in heating mode
Minimum outdoor fan speed in heating mode.
Defines the minimum oudoor fan speed during proportional regulation in
heating mode. It is expressed as percentage (100% = 10V).
Maximum outdoor fan speed in heating mode.
Defines the maximum oudoor fan speed during proportional regulation in
heating mode. It is expressed as percentage (100% = 10V).
