NOTE:
If AoC=dEP the analog output follow the same behavior that is explained at section 11.
If AoC=MAn the analog output works in manual mode with the percentage An.
Ant
Analog Output kind of action: selects direct or reverse functioning for the
analog output.
LAo
Minimum input value: is the value of input that return minimum or maximum
output value (respectively for direct functioning or inverse functioning of the
analog output).
uAo
Maximum input value: is the value of input that return minimum or maximum
output value (respectively for inverse or direct functioning of the analog output).
oAL
Minimum analog output percentage: is the minimum value for the analog
output.
oAU Maximum analog output percentage: is the maximum value for the analog
output.
An
MANUAL MODE: analog output percentage during manual mode (AoC=MAn).
oAE Analog Output safety value: is the value of the output in case of probe fault.
15. RELAY CONFIGURATION
rLS
Relay presence: allow to enable/disable the relay. no= Relay disabled;
YES=Relay enabled.
rLC
Relay working mode: it configures the functioning of the relay: nP= the relay is
always OFF; Mod=the output change its ON/OFF time following the temperature
of regulation probe (obtained by rPA/rPb/rPE). The regulation is direct or inverse
depending on the CH parameter.

rLC=Mod and CH=dir
--------- --------- --------- --------- --------- --------- ---------
rLC=Mod and CH=ind
--------- --------- --------- --------- --------- --------- ---------
For rLC=dEP the relay works as described in paragraph 10. For rLC=tER the
relay works as a simple thermostat in cooling mode if CH=dir and in heating
mode if CH=ind. In this case, the SET and Hy are used. For rLC=Man the relay
works as manual mode, its output percentage (PWM) is roP, so if roP=0 the
relay is always OFF, if roP=100 the relay is always ON.
Ltr
Lower trimmer offset (only for XH55P): Offset added to setpoint when the
trimmer is at minimum value.
Utr
Upper trimmer offset (only for XH55P): Offset added to setpoint when the
trimmer is at maximum value.
tAr
PWM period: ON/OFF period for relay PWM.
LrL
PWM minimum percentage: minimum value for PWM duty cycle. The minimum
ON time for the relay is LrL*tAR/100 minutes. This limit is neglected in case of
working in manual mode.
urL
PWM maximum percentage: maximum value for PWM duty cycle. The relay
can be switched ON for at maximum the time urL*tAR/100 minutes. This limit is
neglected in case of working in manual mode.
XH50-55P
roP
MANUAL MODE: relay output percentage during manual mode rLC=MAn.
rLo
PWM safety value: in case of probe error the relay works in PWM mode with
percentage defined by rLO. If rLO=0 the relay is switched OFF, if rLO=100% the
relay is switched ON.
ALP Probe selection for temperature alarm: nP=not present, alarm disabled;
Etr=external probe; int= internal probe; teq=virtual probe.
ALL
Minimum temperature alarm.
ALU Maximum temperature alarm.
AFH Differential for temperature alarm.
ALd
Temperature alarm delay.
dAo
Delay for temperature alarm at start-up.
diS
Digital input presence: enable or disable the digital input activity . no= digital
input disabled; YES=digital input is present.
idF
Digital Input function: defines the working mode for digital input
(!!!WARNING!!!: the digital input polarity is defined following the paragraph 6)
between En= regulation enabling; ES=energy saving; inA= inversion of kind of
action (relative to CH).
idd
Digital Input delay: is the delay of activation of digital input.
