3.4 Installation shutdown

CAUTION

Do not switch off the mains supply to the appliance. If the central heating system is not used for a long period, we recommend activating the HOLIDAYS mode (to ensure the anti-grip of the heating pump).

3.5 Frost protection

CAUTION

4 The antifreeze protection does not function if the

appliance is switched off.

4 To protect the installation, set the appliance to

HOLIDAYS mode.

The HOLIDAYS mode protects:

4 The installation if the outside temperature is lower than 3°C

(factory setting).

4 The room temperature if a remote control is connected and the

room temperature is lower than 6 °C (factory setting).

4 The domestic hot water tank if the tank temperature is lower

than 4 °C (the water is reheated to 10 °C).

To configure the holidays mode: ¼ See chapter: "Selecting the operating mode", page 14.
