Batteries ran out
The set temperature is too high or too
low.
The air filter is clogged
Check that there are no other obstacles
of the air flow both inside and outside.
The appliance
does not cool/
The thermal refrigeration load has
heat enough.
increased (for example, a door or
a window has been left open or an
appliance has been installed in the
room, generating a lot of heat).

Solution
Check the voltage (by turning the light on, for example).
Check that the exclusive magneto-thermic switch that protects
the appliance hasn't intervened (if it has, reset it). If the problem
repeats immediately, please call the Service Centre and avoid
trying to make the appliance work.
Check that the appliance turns on using the touch-screen display
and substitute the batteries.
Check and
adjust the temperature on the remote
Check the air filter and clean it if necessary
Remove anything that might block the air flow.
Try to reduce the thermal refrigeration load of the room with the
following advice:
Cover large windows exposed to sunlight with curtains or with
external maskings (blinds, porches, reflecting films, etc.);
The room must remain closed for as long as possible;
Avoid turning on halogen lamps or other high energy consumption
appliances such as small ovens, steam irons, cooking plates etc.
Functioning
It is still possible to activate the Cooling, Dehumidification and
Heating modes. It only monitors the antifreeze function of the
internal battery.
None of the functioning modes works.
None of the functioning modes works.
It is still possible to activate the Cooling, Dehumidification and
Heating modes. Defrosting is performed at fixed times.
None of the functioning modes works.
None of the functioning modes works.
None of the functioning modes works.
The appliance only works if the contact is closed. Check that the
clamps are connected.
During cooling and dehumidification, electronics switches the
compressor off and keeps the water distribution system active
with the battery - together with the fan - to disperse excess
water in the container. During heating, condensations should
drain freely through the specific pipe. In the event of an alarm,
check that the condensation pipe is not bent or obstructed, thus
preventing the water from flowing out.
