Troubleshooting
After batteries have been placed into the controller, the
display is not lit:
• Batteries are exhausted or have the wrong polarity; replace
batteries or check polarity.
When pressing the start button, unit does not start and does
not acknowledge signal with a beep:
• Main switch is OFF, switch it to ON.
• Controller batteries are exhausted; replace.
• Controller has not been pointed correctly to the unit receiver;
turn controller off and repeat the operation in the correct
direction.
• There are obstacles (curtains, walls, etc.) between the controller
and the unit; repeat the operation after having removed the
obstacles.
• Receiver on the unit or the remote controller is under intense sun
radiation; avoid direct sun on the unit, shut curtains or shades.
• Signal transmission is obstructed by severe interference from an
electromagnetic field; avoid sending signals when computers or
household appliances (food processors, coffee grinders, etc.) are
operating close by.
Cellular or cordless telephones may also interfere with the
control.
When pressing the stop button unit does not turn off and
does not acknowledge signal with a beep:
• Controller batteries are exhausted; replace.
• Controller has not been pointed correctly to the unit receiver; turn
controller off and repeat the operation in the correct direction.
• There are obstacles (curtains, walls, etc.) between the controller
and the unit; repeat the operation after having removed the
obstacles.
• Receiver on the unit or the remote controller is under intense sun
radiation; avoid direct sun on the unit, shut curtains or shades.
• Signal transmission is obstructed by severe interference from an
electromagnetic field; avoid sending signals when computers or
household appliances (food processors, coffee grinders, etc.) are
operating close by. Cellular or cordless telephones may also
interfere with the control.
When pressing any function button, controller shows the
function requested on the display, but unit does not
acknowledge signal receipt with a beep and does not carry
out the function:
• Controller batteries are exhausted; replace.
• Controller has not been pointed correctly to the unit receiver; turn
controller off and repeat the operation in the correct direction.
• There are obstacles (curtains, walls, etc.) between the controller
and the unit; repeat the operation after having removed the
obstacles.
• Receiver on the unit or the remote controller is under intense sun
radiation; avoid direct sun on the unit, shut curtains or shades.
• Signal transmission is obstructed by severe interference from an
electromagnetic field; avoid sending signals when computers or
household appliances (food processors, coffee grinders, etc.) are
operating close by. Cellular or cordless telephones may also
interfere with the control.
When pressing any button display will not change:
• The triangle symbol 2
is on, as another signal is being
transmitted; wait for signal 2
to disappear and repeat the
operation.
Air conditioner will not start:
• Main supply switch is OFF; switch to ON.
• Fuses on main switch are blown; replace fuses.
• Wait for 3 minutes: protection against frequent compressor
cycling is on.
• Selected temperature is higher than the room temperature (or
lower in the heating mode).
Air conditioner is not supplying enough cooling (or heating):
• Air flow cannot circulate freely.
• Dirty filters reduce air quantity circulating.
• Doors and/or windows are open.
• Fan speed has been set to “low”.
• Air flow direction is not correct.
• Selected temperature is not correct.
A slight mist is emitted from the unit:
• A slight mist, coming out of the unit air outlet, can sometimes be
noticed during cooling operation.
This is due to the cool air coming into contact with the room air.
A slight whistling noise is heard when the air conditioner
starts or stops:
• This is due to the refrigerant beginning to circulate or an
adjustment of the refrigerant pressures.
Flashing LEDs P (green) and R (yellow):
System malfunction.
Contact service organization after having made the following checks:
• Filters are clean.
• Air circulation is not obstructed.
• Outdoor unit coil is not obstructed with a severe reduction of air
circulation.
Refer to the installation manual for fault code reading to be notify
to service organisation.
Restart air conditioner after having corrected the faults.
Water vapour (mist) emanating from the outdoor unit:
• It is normal in heat pump operation, when defrost is
automatically activated.
Unpleasant smells coming from the unit:
• Unpleasant smells can be caused by substances accumulated in
the air filter.
Switch the unit off and contact an authorised service centre to
have the filters cleaned. Restart unit in the ventilation (fan only)
mode and open windows to change room air.
Strange noises coming from the unit:
• Occasionally the unit can emit some strange short noises during
operation or when it has stopped. These are generally due to the
effect of temperature changes on the plastic parts.
Starting in heating mode for heat pump systems:
• If the unit starts at low ambient temperatures, it takes a little
while to reach a comfortable room temperature.
When the unit is started by the remote control, it emits a signal
beep, but the louvre does not swing and the fan does not run
until the operating temperature has been reached.
