Make sure that you have set the correct day for the "Off" time. You must program the day for both the "On" time and the "Off" time.
It is not sufficient to set the day for the "On" time, as this is not automatically adopted for the "Off" time.
Make sure that the same combination of days is set for the "Off" time, especially for multi-day programs.
Attention: When switching off after 0 o'clock, set the next day for the "Off" time, as the next day is after 0 o'clock.
