Druk die PROG button allows you to navigate through programming menus or return to the normal time program.

5.2 Understanding Thermostat Modes

The thermostat operates by controlling the heating system based on three adjustable temperature settings at specific times:

• Geriefstemperatuur: Typically used during the day or periods of presence.
• 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).
