The thermostat can switch on your heating system at predetermined times on different days of the week. For each day of the week, you can set individual temperatures for 4 different periods, called events. Lowering the temperature when the home is unoccupied will reduce your energy costs without reducing comfort. The thermostat comes with a default schedule suitable for most homes. Unless you change the settings, the thermostat will operate in compliance with the default schedule. Furthermore, the thermostat features an adaptive function that automatically changes heating period start times so as to ensure that the required temperature is reached at the set time. After three days the adaptive function has learned when the heating must be switched on.
First-time settings
The interrupter button allows you to turn the thermostat on “I” and off “0” by sliding the button up and down. When the thermostat is switched off to “0”, the relay disengages. All settings, including time and date, will be remembered. The thermostat is intuitively operated using the navigation buttons. The function of each button is indicated above the button in the display.
