Understanding your needs with smartness! The Siemens Smart RDS110 Thermostat has been developed to provide professional control and operation of heating applications. With its clean design it fits perfectly into every interior. It is always in touch with its surroundings thanks to six powerful and accurate sensors: temperature, humidity, light, proximity, presence and organic particle detection. Since all of them are an integral part of the Smart Thermostat, no additional wiring or programming is needed. These sensors allow the Smart Thermostat to be fully autonomous.
