THE BOOST CAN STOP FOR
3 DIFFERENT REASONS:
AN ORDER «STOP» HAS BEEN SENT BY YOUR EN-
ERGY MANAGER THROUGH THE PILOT WIRE:
The blower stops, -- appears. The cursor moves above
auto. When the order Comfort will be sent, the blower
will be restarted until the count end.
FILT APPEARS ON THE DISPLAY:
The blower continues to operate but does not heat up.
Check if nothing is put in front of the ventilation grid to
not block the air flow. The filter could be plug by dust, it
must be cleaned (see page 74).
POST-VENTING
When the blower and the heating cartridge switch off,
the venting continues to operate during few seconds to
preserve and optimize the product life time.
Seconds appear and begin to count down, the keypad is
inactive during the post-venting.

Comment: if the filter is obstructed or if the grid is covered
involuntary, a special sensor switches off the device. The
normal operating of the device will start again at the next
start-up, if the filter or the grid is not obstructed, and only
after the blower has cooled down.
IF THE AMBIENT TEMPERATURE REACHES THE
MAXIMAL BOOST TEMPERATURE DURING THE
COUNT:
The blower switches off but the Boost mode is always
active : the count is always displayed, the Boost symbol
and the heating indicator flash on the display. When the
temperature drops under the maximal authorised temper-
ature, the blower will be restarted until the count ends.
SECOND PRESS = BOOST CANCELLATION.
The cursor moves above the previous active mode and
the setting temperature appears.
