Control the outputs via RS485 serial connection
The status of the analogue output and the relays on the instrument can
be controlled via a serial connection to a supervisor.
The variables are read only if LIn=no, or read/write if LIn=yES
The variables are described in the table of supervisor variables and must
be used according to the current mode (T, T2, T2A,...), the status on the
LCD automatically shows the outputs.
Important: This function, if enabled, completely replaces the
control performed by the instrument. In this operating mode,
together with the outputs, the symbols displaying the operating status of
the instrument are also activated according to the current mode.
Note: If the instrument is not queried for more than two minutes,
“override” mode is disabled:
all the outputs are disabled;•
the no link error (ELn) is signalled on the display.•
code description of the parameter
LIn
Enabling this parameter allows the outputs to be controlled directly via the serial connection.
Warning, if enabled no control is performed independently by the instrument.
If active and the supervisor does not query the instrument for more than two minutes, the outputs are
automatically disabled and the no link error (ELn) is signalled on the display.
no: The function is disabled. yES: The function is enabled.

Control cooling/heating mode via RS485 serial
connection
This function allows the operating mode, cooling/heating, to be selected
by parameter (including via serial connection), rather than on the
dipswitches. If the function is enabled, the dipswitch setting is ignored
and the operating mode is de ned using parameter EI.
code description of the parameter range def. UOM
EI
Control cooling/heating operating mode
Enables the possibility to de ne the operating mode, cooling/heating, by parameter rather than by DIP 4.
dIS: Parameter EI is disabled, cooling/heating mode is selected by DIP 4 on the rear.
En: Parameter EI is enabled, cooling/heating mode is selected by parameter EI.

Programming operation cooling heating
Select cooling/heating operation
Selects the mode, cooling or heating. This parameter is only active if this mode is enabled by the previous
parameter.
E: The instrument works in cooling mode
I: The instrument works in heating mode

Remote temperature/humidity sensor
For the models without the humidity sensor already installed, a remote
sensor for ducts (temperature + humidity) can be connected, up to a
maximum distance of 3 m.
The sensor is purchased separately, code ADCF006500. This code includes
the wired cable in the maximum available length (3 m).
The remote temperature/humidity sensor can be installed on all ADCA***
codes.
Note: The remote temperature/humidity sensor cannot be
connected to controller codes ADCF*** and ADCD*** that already
have a built-in humidity sensor, as this would cause the temperature and
humidity measurements to freeze.
To retro t a clima model ADCF*** or ADCD*** already installed with a
remote sensor, open the controller and remove the plug-in card with the
temperature/humidity sensor from the PCB, as shown in the  gure.
