The Away Mode is designed to put your Home in a state that is sensible when you leave it for longer periods of time (e.g. being away for the weekend).
The default setting of the Away mode is to set the target temperature of all rooms in your Home to 16 °C.
You can change the target value and even add devices and their behavior to the Away Mode.
On the Automation Screen (A):
Tap Away Mode (B) to activate or deactivate the Away Mode.
If Boost Mode is active, Away Mode will lower the target temperature of all boosted heaters, if the Boost value is higher than the Away Mode value.
You can set the target temperature and affected devices in the Settings menu -Away Mode .
