6. Operating Instructions
The Hager EK570 offers various operating modes and programming options to optimize your heating.
6.1. Selecting Operating Modes
The thermostat supports the following modes:
- Comfort Mode: Maintains a comfortable temperature (e.g., 21°C) during occupied periods.
- Reduced Mode: Maintains a lower, energy-saving temperature (e.g., 18°C) during unoccupied periods or at night.
- Frost Protection Mode: Maintains a minimum temperature (e.g., 5°C) to prevent pipes from freezing.
- Manual Mode: Allows you to set a constant temperature that overrides any programmed schedule.
- Holiday Mode: Maintains a specific temperature for an extended period (e.g., during vacation).
To switch between modes, press the 'MODE' button repeatedly until the desired mode is displayed.
6.2. Adjusting Temperature Setpoint
In any operating mode (except Frost Protection), you can temporarily adjust the temperature setpoint:
- Use the '+' or '-' buttons to increase or decrease the desired temperature.
- The new setpoint will be active until the next programmed event or until you manually change it again. This is known as a temporary override.
