Room thermostat with touchscreen

21 October 2014

• Touchscreen for easy and convenient operation
• Wide range of applications, thanks to KNX support
• Numerous integrated energy-saving functions

The Siemens Building Technologies division has added the KNX-capable RDF800KN model to its range of communications-enabled room thermostats. The device can be integrated into various building automation systems via KNX,supports a wide range of applications and offers numerous energy-efficiencyfunctions.

With the RDF800KN, Siemens presents a modern touchscreen-based roomthermostat. Combined with an intuitive operating concept, which was optimized inextensive user tests, the touch functionality makes the device easy and convenientto use so that it is particularly suitable for applications in hotels and residentialbuildings.

Thanks to KNX support, the RDF800KN can be easily connected to buildingautomation systems such as Desigo, Synco and Gamma from Siemens as well as tomany systems of third-party suppliers. With the Synco web server from Siemens,users can also access the room thermostat over the Internet and monitor or changeits settings and readings.

During operation, the RDF800KN exchanges all information relevant to energy consumption with the connected system. The device automatically selects the most energy-efficient settings on the basis of this data. The room thermostat also has numerous energy saving functions that can be set manually, including demand-based air handling, individual room control with centrally defined setpoints, setpoint limits for heating, cooling and fan speed control, timer programs as well as apresence/absence detection function. Two multifunction inputs allow for theconnection of elements such as window contacts and presence detectors; the interaction between the disciplines offers energy-savings potential, for example by turning off the heat when windows are opened or rooms are not being used.

The RDF800KN supports a wide range of applications for fan coils, heating/cooling systems and heat pumps. The room temperature is controlled either with the integrated temperature sensor or an external room or return air sensor. The basic functions include automatic or manual change over between heating and cooling inthree modes (Comfort, Economy and Protection), automatic or manual fan controland limiting of room temperature setpoints.
