POSSIBLE CAUSES
• No power supply
• The power switch is in "0" position
• Remote control batteries are flat
• The temperature set on the remote control is either
too high or too low (when using the
heating pump unit).
• The air filter has been blocked before the
respective cleaning LED was switched on.
• Indoor or outdoor air flow obstacles are present.
• The heating/cooling load has increased (for example
a door or a window was left open or equipment that
dissipates a large amount of heat was installed in the
same room);
• Both the internal units are running; the heating load is
greater than the power of each internal unit.
OPERATIONAL LIMITS
• Check that mains power is present (by turning on
• Check if the master switch is closed or if a fuse
• Move the power switch to "1" position (fig. 42 ref.
• If the batteries are flat, you will notice that no
• Check the temperature setting on the remote
• Check the air filter and clean it if necessary.
• Remove anything that might clog the air flows.
• Switch off one of the two internal units.
