digital input
XT110C and XT111C have 1 free contact
digital input. It is programmable in 5
different configurations by the “
i1F”
parameter.
invert the kind of action: heatingcooling
(I1F = C-H)
This function allows to invert the regulation
of the controller: from direct to inverse and
viceversa.
REMOTE ON/OFF (I1F = OFF)
This function allows to switch ON and OFF
the instrument.
GENERIC ALARM (i1F = EaL)
As soon as the digital input is activated the
unit will wait for “did” time delay before
signalling the “EAL” alarm message. The
outputs status don’t change. The alarm
stops just after the digital input is deacti-
vated.
serious alarm mode (I1F = BAL)
When the digital input is activated, the unit
will wait for “did” delay before signalling the
“bAL” alarm message. The relay outputs are
switched OFF. The alarm will stop as soon as
the digital input is de-activated.
energy saving (I1F = HES)
The Energy Saving function allows to change
the set point1 value as the result of the SET1
+ HES (parameter) sum. This function is en-
abled until the digital input is activated.
ALARM SIGNALS
alarm relay status (XT111c)
Silencing buzzer / alarm relay output
Once the alarm signal is detected the buz-
zer, if present, can be disabled by pressing
any key.
