Siemens Series 2200 Carbon Dioxide Room Units for Programmable BACnet TEC

The Series 2200 CO2 Room Units from Siemens Industry, Inc. offer a wide range of features and functionality that work in concert with the APOGEE® Automation System to deliver exceptional occupant comfort in even the most demanding application environments. The product family includes plain, sensing-only variants, and fully interactive types with a graphical OLED (Organic Light Emitting Diode) displays. All room units incorporate precision CO2 and temperature sensing elements to accurately and reliably measure room temperature and carbon dioxide. Their compact, low profile design results in an attractive, inconspicuous installation. Strategically placed ventilation slots in the housing optimize airflow through the cover for fast measurement response and superior control.

The Series 2200 CO2 Room Units incorporate digital CO2 and temperature integrated circuits and a plug-in HMI (Human-Machine Interface) port located on the bottom of the cover. The HMI port provides a convenient means of communicating with the controller to command or troubleshoot the system. These room units connect to the controller via a six-wire cable terminated with a plug-in RJ-11 connector. The cable transmits the temperature, the communication with the HMI, and the optional temperature setpoint and override signals.
