# VAT (Temperature holiday mode)

![](https://faqdoc.info/wp-content/uploads/2026/01/Matrix_55__icon_Elektro-Wasser.png)

The desired temperature in holiday mode can be individually selected between 5 °C and 30 °C.

The default settings are 17 °C (63 °F) in heating mode and 26 °C (86 °F) in cooling mode – if the system is water-based.

**NOTE**
The cooling mode is obviously not available with electric heating.
