Whether you’re setting the time, duration, or temperature of heating and energy saving phases, it’s child’s play to use the display, program selection slider, and large buttons. The program selection slider leads you through all of the settings. The text display provides information on what each setting means. The display is very easy to read and navigate: Only the current values and icons are visible, and thanks to backlighting, you can read the display even in the dark. And you don’t need to change the settings when daylight saving time begins and ends: The thermostats automatically readjust the time of day and date when necessary.
