INFORMATION ABOUT REMOTE CONTROL BY
PILOT WIRE
OVERVIEW
Your device can be controlled by a central control unit
through a pilot wire, in which case the different operat-
ing modes will be remotely enabled by the programmer.
You can only control the device by pilot wire in the Auto
mode. In the other modes, the orders transmitted by the
pilot wire will not be executed.
In general, a pilot wire control system makes it possible
to impose externally a lowering of the temperature set-
point, combined with the internal programming and the
presence detection. If several lowering requests appear
simultaneously, priority is given to the lowest tempera-
ture setpoint, thus maximizing savings
(see information on
priorities for different modes on
page 60)
. When a signal
is sent from the pilot wire, the self learning optimization
function is suspended.

This feature allows you to modify temporarily the setting
temperature until the next order sent by the central control
unit or the transition to 00:00.
Example:
①
The device is in Auto mode. The central control unit
sent an Eco order 15,5°C.

②
By pressing
or
, you can modify temporarily
the setting temperature up to 18°C for example.
Note :
The cursor corresponding to the operating mode,
i.e Eco mode in our example, is blinking during the duration
of the temporary derogation.
③
This modification will be automatically cancelled at
the next order sent by the central control unit or the
transition to 00:00.
