RDG – the electronic room thermostat that allows you to set the ideal room temperature you want.
The thermostat satisfies your individual needs in all operating modes: Comfort, Economy and
Protection. The fan operates either in Automatic mode or at the selected speed when using Manual
mode. You can either rely on the factory settings or make adjustments that suit your individual needs.
