Temperature and CO2 Room Controller (CTC)

C Squared have developed the iSC™ range of intelligent temperature, humidity and CO2 sensors - the latest concept in intelligent sensor technology. Specifically designed to meet the HVAC control requirements of modern building systems that communicate using the open source BACnet protocol. We are also able to supply complete Building Management Systems (BMS) packages.
