- Setback Temperature (Economy/Night): Usually applied during the night or periods of absence to save energy.
- Frost Protection Temperature: Used during extended periods of absence (e.g., holidays) to prevent the heating system from freezing. This temperature is set just high enough to protect the system.
5.3 Weekly Timer Programming
The integrated weekly timer allows for time-controlled temperature management for a single room or floor heating. You can set up to 32 individual switching times throughout the week. For each switching time, you define the start time, end time, and the desired temperature mode (Comfort, Setback, or Frost Protection).
