In case of Reheat only domestic hot water preparation, the desired
tank temperature is weather dependent (according to the weather
dependent curve). During weather dependent operation, the end-
user cannot adjust the desired tank temperature on the user
interface. Also see

About holiday mode
During your holiday, you can use the holiday mode to deviate from
your normal schedules without having to change them. While holiday
mode is active, space heating/cooling operation and domestic hot
water operation will be turned off. Room frost protection and anti-
legionella operation will remain active.
Typical workflow
Using holiday mode typically consists of the following stages:
1
Setting the starting date and ending date of your holiday.
2
Activating the holiday mode.
To check if holiday mode is activated and/or running
If
is activated on the home screen, holiday mode is active.
