3.5.2 Troubleshooting

In case of malfunctions, check the following table.

If the problem persists after the suggested checks and controls, contact the authorised technical service.

FAULTS POSSIBLE CAUSES SOLUTIONS

The unit does not turn on • No power supply • Check that mains power is present (by turning on

a light for instance).

• Check if the master switch is closed or if a fuse

is burnt (in this case replace the fuse). If there is

a magnetothermal circuit breaker instead of the

master switch, check if it tripped (if it did, rearm

it). Should the problem occur again, contact the

Service Center at once and do not attempt to run

the unit.

• The power switch is in “0” position • Move the power switch to “1” position (g. 42 ref.

A).

• Remote control batteries are at • If the batteries are at, you will notice that no

messages are displayed and that the unit’s

reception conrmation sound is missing when

you try to issue any command to it. In this case

replace the batteries.

The unit does not cool or

heat adequately

• The temperature set on the remote control is either

too high or too low (when using the

heating pump unit).

• Check the temperature setting on the remote

control and correct it if need be.

• The air lter has been blocked before the

respective cleaning LED was switched on.

• Check the air lter and clean it if necessary.

• Indoor or outdoor air ow 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);

• Remove anything that might clog the air ows.

• Both the internal units are running; the heating load is

greater than the power of each internal unit.

• Switch off one of the two internal units.

Resetting the bipolar safety thermostat (ref. D g. 35)

In the event the water heating up abnormally, a thermal safety switch conforming to CEI standards interrupts the

electrical circuit on both phases supplying the heating element with power; if this happens seek the intervention of

Service Assistance.
