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
"8.3.7 Detailed screen with weather-dependent
curve" on page 44 .

INFORMATION
By default, daylight savings time is enabled and clock
format is set to 24 hours. If you want to change these
settings, you can do this in the menu structure (User
settings > Time/date) once the unit is initialised.
Holiday
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.
