Night mode allows you to have a lower temperature at night, which usually means better sleep and greater comfort. In addition to changing the temperature, you can also change the status screen backlight, set any AC to night mode (Truma AC), switch off hot water and underfloor heating, and change the temperature sensor, if you have an extra sensor installed in e.g. the sleeping area.
In this example, we’re setting the desired temperature on the main menu to 22 °C. This is our “normal” setting. We set night mode to 17 °C, starting at 22:00 and ending at 06:00, when we get up. At 06:00, the desired temperature will return to 22 °C, which is the default setting in the main menu.
