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 interval of time 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 a heater element, for example. 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.
13. DIGITAL INPUTS
The digital inputs are programmable by using par.
i1F
and
i2F
.
13.1 DOOR SWITCH (ixF=dor)
It signals the door status. Some relay outputs can be toggled depending on the
odC
parameter:
odC = no
no change
odC = FAn
evaporator fan will be switched off
odC = CPr
compressor will be switched off
odC = F-C
both compressor and evaporator fan will be switched off
Since the door is opened:
the door alarm is enabled
the display shows the message “dA”
the regulation restarts only if
rrd = Y
.
The alarm stops as soon as the external digital input is disabled again. During open door conditions, the high
and low temperature alarms are disabled.
