The fan symbol is
flashing. No heat
and the fan runs at
maximum speed.
The text "Heat OFF"
appears. No heat.
The text "Sens Out"
flashes in the display
and there is no heat.
The text "Sens In"
flashes in the display
and there is no heat.
The fan convector emits
heat, but it becomes
progressively more
difficult to achieve
the desired room
temperature, even
though the settings are
unchanged.
All the fans are inactive.
The internal temperature has exceeded
the upper limit, even though the heat
is off. The fans automatically run at the
highest speed and the heat is blocked
until the internal temperature is below
the limit, and then return to the previous
settings.
The control considers that no heat is
emitted from the heating element. (The
temperature difference between the
room sensors and internal sensors is
less than 5 °C after 90 sec.)
The upper sensor is defective or is de-
tached from its fastening.
The lower sensor is defective or is de-
tached from its fastening.
The internal temperature reaches its limit
value faster, which limits the heat emis-
sion.
• Check that the air flow is not
blocked at the intake grille or
outlet grille.
• Clean the inside of the unit.
• Check that the internal sensor
(at the outlet grille) are placed
correctly.
• Check that the air flow is not
blocked at the intake grille or
outlet grille.
• Disconnect the power for at least
10 minutes in order to reset the
overheat protection.
• Reconnect power and cancel the
alarm by pressing the OK button
for 3 seconds.
