•
odC=F-C : compressor and evaporator fan OFF
When rrd=Y , the regulation restarts after d1d or d2d time.
11.
CONDENSER FAN
To enable the condenser fan management, setting a condenser probe is required (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.
12.6 AUXILIARY OUTPUT (oAx = AUS)
The auxiliary output can be managed by digital inputs ( oAx=AUS , i1F or i2F=AUS ): the output is switched
on and off following the relative digital input status.
12.6.1 AUXILIARY REGULATOR
The auxiliary regulator can be used to manage the auxiliary output. Here are the involved parameters:
•
ACH: type of regulation for the auxiliary relay: Ht = heating; CL = cooling
•
SAA: set point for auxiliary relay
•
SHY: auxiliary relay differential
•
ArP: probe for auxiliary relay
•
Sdd: auxiliary output off during defrost
12.6.2 TIMED ACTIVATION
The following parameters can be used to define fixed activation and deactivation intervals.
•
btA: base time for auxiliary output activation and deactivation intervals
•
Ato: auxiliary activation interval
•
AtF: auxiliary deactivation interval
