11.1 Resetting the safety thermostat

Danger

Before carrying out any work on the indoor unit, cut off its power

supply and the electrical back-up immersion heater.

If you suspect that the safety thermostat was triggered:

1. Cut off the power supply to the indoor unit and the electrical back-up

immersion heaters by lowering the circuit breakers on the electric

panel.

2. Locate and correct the cause of power cut before resetting the safety

thermostat.

3. Remove the front panel of the indoor unit and the protective cap.

4. If the safety thermostat has been triggered, use a flat-headed

screwdriver to press the reset button on the thermostat. If not, look for

an alternative cause for the power to the immersion heater having

been cut.

5. Refit the front panel on the indoor unit and the protective cover.

6. Switch the mains supply to the indoor unit and the electrical back-up

immersion heater back on.

11.2 Resolving operating errors

If your appliance malfunctions, the status LED flashes and/or changes

colour and a message containing an error code is displayed on the main

screen of the control panel. This error code is important for the correct and

rapid diagnosis of the type of malfunction and for any technical assistance

that may be needed.
If an error occurs:

1. Make a note of the code displayed on the screen.

2. Remedy the problem described by the error code or contact the

installer.

3. Switch the heat pump off and back on to check that the cause of the

error has been removed.

4. If the code is displayed again, contact the installer.

11.2.1 Types of error code

The control panel can display three types of error codes:

Tab.95

Type of code

Code format

Colour of the status LED

Warning

Axx.xx

Green flashing

Blockage

Hxx.xx

Continuous red

Lock out

Exx.xx

Red flashing

11.2.2 Error codes

An error code is a temporary status, resulting from the detection of a heat

pump anomaly. The heat pump attempts to restart automatically until it

switches on.
When one of the following codes is displayed and the heat pump cannot

restart automatically, contact a maintenance technician.
