Frequent questions

I changed the temperature, but the central unit did not receive the change?
If you have set your thermostat higher than the actual room temperature, and no LED on the SCU209DE has blinked, you will need to resynchronise the thermostat with the unit.
Is the SCU209DE control unit not working properly?
If you find that the SCU209DE is not working properly, check the power cable and other connections.
Is it normal for the light in an area to always be on?
Yes, this is normal if a thermostat has been successfully connected to the area. The lit light indicates connectivity in optimal operating parameters.
