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
12.6.3 GENERAL NOTES
If oAx=AUS and ArP=nP (no probe for auxiliary digital output) the AUX output can be managed:
•
by digital input if i1F=AUS or i2F=AUS
•
by auxiliary button if set as AUS
•
by serial command (Modbus protocol)
•
by fixed time interval if Ato>0 and AtF>0 (if Ato=0 or AtF=0 the auxiliary output is disabled)
12.7 DEAD BAND REGULATION (oAx = db)
With oAx=db the output can be used to control, for example, a heater element. It is used to implement a
dead band regulation. If so:
•
oAx=db cut-in is SET-HY
•
oA1=db cut-out is SET
12.8 ON/OFF OUTPUT (oAx = onF)
When oAx=onF, the output is activated when the controller is switched on and deactivated when the
controller is switched off.
12.9 ENERGY SAVING OUTPUT (oAx = HES)
When oAx=HES, the output is activated when the energy saving mode is active and vice-versa.
12.10 CONDENSER FAN OUTPUT (oAx = Cnd)
With oAx=Cnd the relay operates as a condenser fan output.
12.11 SECOND COMPRESSOR OUTPUT (oAx = CP2)
With oAx=CP2 the relay operates as a second regulation output. This function is available only for special
models and normally must be not selected.
12.12 SECOND DEFROST OUTPUT (oAx = dF2)
With oAx=dF2 the relay operates as second defrost output. This function is available only for special models
and normally must be not selected.
12.13 HEATER OUTPUT (oAx = HEt)
With oAx=HEt the relay operates as a heater output. In this case, it will be used during and after any defrost
cycle. The par. Hon defines the time the relative output will stay active after the end of a defrost operation.
12.14 INVERTER OUTPUT (oAx = inV)
Function not available for this model.
