Programming by pilot wire
If you do not want to use the programming feature, the device’s default setting
is non-stop Comfort for 7 days a week, you do not have to change any settings.
Orders sent by the pilot wire will only be applied in Auto mode , thus your device
will automatically receive and apply the programmed orders sent by your
power manager or your time switches (see Information about remote control
by pilot wire page 9).

Without programme
if the 7 day and daily programme is not enabled or no orders are being sent
by pilot wire, then your device’s factory settings mean that it will operate in
nonstop Comfort mode, 7 days of the week.
• Comfort mode
Non-stop Comfort mode. The device will
operate 24 hours a day to achieve
the temperature which has been set (e.g.
19°C). The Comfort mode temperature le-
vel can be set by the user (see Setting the
comfort mode temperature page 6).

GAUGE CONSUMPTION, ENERGY SAVINGS
France’s Agency for Environment and Energy Management (ADEME)
recommends a Comfort setting temperature lowerr or equal to 19°C.
In the device display, a selector indicates the energy comsumption level
by positioning it in front of the colour: red, orange or green. So, depen-
ding on the setting temperature, you can choose your level of energy
usage. As the temperature setting
increases, the consumption will be higher.
The gauge appears in Auto, Comfort, Eco and Frost protection modes
and whatever the temperature level.
