About TEM AG
TEM AG, headquartered in Chur (Switzerland), develops and produces components and systems for building automation and energy management. The product range includes control and regulation electronics for heating, ventilation and air conditioning (HVAC), controllers for oil, gas, wood and pellet heating systems, heat pumps and solar installations, as well as the myTEM smart building system with servers, IO devices and Z-Wave-compatible components. The products are available as wired solutions (Smart Server), via radio (Radio Server) or in hybrid form, and can be integrated into existing technology via open interfaces such as Z-Wave, DALI, Modbus and BACnet; operation is local without any cloud requirement. In addition to its own product range, the owner-managed company offers OEM product development, consulting and project planning, technical support and training. The products are used throughout Europe in HVAC applications; target groups include OEM customers, prefabricated house manufacturers, electrical planners, architects, building owners and building managers.
