37.2 PWM
OUTPUT FOR FAN CONTROL
If FA01=3 and the fan control boards are connected to the PWM outputs (TF1 and2) take note of the FA03 ,FA04 parameters.
The fan start-up is always made at the maximum speed for the time set in FA03, then the speed follows the probe value.
The F04 delay, in micro – seconds, allows to adjust the output for each kind of the fan motor.
If FA01=3, when the compressor starts-up and the proportional regulation requires to turn off the fan (cut-off), if FA14
≠
0 the fan is forced
at the minimum speed for the time set in FA14 itself. if FA14=0 the function is disabled.

CONDENSING UNIT
:
COMMON OR SEPARATE
FA05 defines the condenser unit
Par. FA05 type of condenser
0= Common condenser unit.
1= Separate condenser units.
If Pa FA05= 0 the outputs, configured as condensing fan control, will follow the same regulation algorithm.
The regulation includes:
•
CHILLER mode: the maximum probe value compared between the temperature/pressure probe of the two circuits.
•
HEAT PUMP (no evaporator probe configured) the minimum probe value compared between the condenser
temperature/pressure probe of the two circuits.
•
HEAT PUMP (evaporator probe configured) the minimum probe value compared between the evaporator temperature/pressure
probe of the two circuits.
If par. FA05 = 1 and if the evaporating pressure probe are not configured, the fan output controls are separated and are controlled by
the condenser temperature/pressure probes. When the evaporator probes are configured, in heat pump the ventilation is controlled by
these transducers.
