OPEN WINDOW DETECTION, ENERGY SAVINGS
IMPORTANT INFORMATION ABOUT
THE OPEN WINDOW DETECTION
Important: the open window detection is sensitive to
temperature variations. The device will react to the win-
dow openings in accordance with different parameters:
temperature setting, rise and fall of temperature in the
room, outside temperature, location of the device...
If the device is located close to a front door, the detection
may be disturbed by the air caused by opening door. If
this is a problem, we recommend that you disable the
automatic mode open window detection (see page 65).
You can, however, use the manual activation (see below).

① the favoured location
② another location
The device detects a temperature fall. An opened window,
a door to the outside, can cause this temperature fall.
Note: The difference between the air from the inside and
the outside must cause a significant temperature fall to
be perceptible by the device.
This temperature drop detection triggers the change to
Frost Protection mode.
MANUAL ACTIVATION
By pressing
for more than 5 seconds, the device will
switch on Frost protection mode.
FROST PROTECTION DIGITAL METER
When the device performs a lower temperature cycle
due to opened window, a meter appears on the display
to show the cycle time.The counter is automatically reset
at the next time to Frost protection by opened window
(automatic or manual activation).
STOP THE FROST PROTECTION MODE
By pressing one button, you stop the Frost protection mode.
Note : if a temperature rise is detected, the device may
return to the previous mode (active mode before the
open window detection).
