Holiday mode
Holiday mode
The holiday mode can be activated for times when the building is not inhabited. The venti-
lation unit operates with minimal air exchange in this mode (i.e., ventilation mode 1 will be
active for 16 hrs per day and ventilation mode 0
will be active for 8 hrs per day).
The function can be deactivated by choosing another operating mode, ventilation mode or
after 28 days at the latest.
Deactivate the function immediately after the building is inhabited again
since otherwise this causes an increased risk of condensation in the
pipes, or might lead to moisture damage in the building.
Control unit
This function cannot be set via the control unit.
