Instruction

The CB Manual thermostat control a floor heating system based on a built-in weekly program. You can set individual temperatures for 4 events or 2 events on different days of the week. The default weekly program parameters can satisfy most installations. If your living habits are different, you can update the weekly program parameters in the thermostat or APP. Lowering the temperature when the home is unoccupied will reduce your energy costs without reducing comfort. Furthermore, the thermostat features
an adaptive function that automatically changes heating period start times to ensure that the required temperature is reached at the required time. After some days the adaptive function has learned when the heating must be switched on.
