Q: Can I create different heating schedules for weekdays and weekends?

A: Yes. The weekly program supports 5+2, 6+1, or 7-day scheduling modes. Weekdays allow up to 6 time slots, while rest days support 2 time slots, each with its own target temperature — perfect for customizing your heating around your lifestyle.

Q: What is the anti-frost function and how does it work?
