•
HYF : differential
•
FnC : to define the working mode:
o
C-n: in parallel with compressor output and stopped during any defrost. When compressor is OFF,
they will start a duty-cycle mode (see FoF , Fon , FF1 and Fo1 parameters)
o
O-n: always on, stopped during any defrost
o
C-Y: in parallel with compressor output and always on during any defrost. When compressor is
OFF, they will start a duty-cycle mode (see FoF , Fon , FF1 and Fo1 parameters)
o
o-Y: always on
•
Fnd: activation delay after any defrost
10.1 EVAPORATOR FAN AND DIGITAL INPUT
When a digital input is configured as a door switch ( i1F or i2F=dor ) and this digital input is active, evaporator
fan and compressor status will depend on par. odC :
•
odC=no : normal regulation
•
odC=FAn : evaporator fan OFF
•
odC=CPr : compressor OFF
•
odC=F-C : compressor and evaporator fan OFF
When
rrd=Y , the regulation restarts after d1d or d2d time.

CONDENSER FAN
To enable the condenser fan management it is required to set a condenser probe (par. FAC ). Here are the
involved parameters:
•
FAC : to select the control probe
•
St2 : to select the deactivation setpoint
•
HY2 : differential
•
FCC : to define the working mode:
o
C-n: in parallel with compressor output and stopped during any defrost. When compressor is OFF,
they will start a duty-cycle mode (see FoF , Fon , FF1 and Fo1 parameters)
o
O-n: always on, stopped during any defrost
o
C-Y: in parallel with compressor output and always on during any defrost. When compressor is
OFF, they will start a duty-cycle mode (see FoF , Fon , FF1 and Fo1 parameters)
o
o-Y: always on

DIGITAL OUTPUTS
Depending on the model, one or more digital outputs (relays) can be configurated with one of the following
functionalities.
12.1 COMPRESSOR OUTPUT (oAx = CP1)
With oAx=CP1 the relay operates as the main regulation output.
12.2 DEFROST OUTPUT (oAx = dEF)
With oAx=dEF the relay operates as a defrost output.
12.3 EVAPORATOR FAN OUTPUT (oAx = FAn)
With oAx=FAn the relay operates as an evaporator fan output.
12.4 ALARM OUTPUT (oAx = ALr)
With oAx=ALr the output operates as an alarm output. It is activated every time an alarm happens. Its status
depends on the tbA parameter: if tbA=Y , the output is deactivated by pressing any key.
If tbA=n , the alarm output stays on until the alarm condition recovers.
12.5 LIGHT OUTPUT (oAx = LiG)
With oAx=LiG the relay operates as a light output.
