The SHSUXXXXL line are bus-powered room sensors for wall-mounting. They are available in different combinations of CO2, temperature and relative humidity. The sensors have a “traffic light” LED which is used to indicate the CO2 level in green, amber or red colour. The only connection needed for the sensor is the Dupline® 2-wire cable. Several sensors can be multi-dropped via the same Dupline® 2-wire bus, thereby simplifying the wiring to the controller significantly. The address assignment and definition of CO2 threshold levels are performed over the bus by using the SBWEB/SHWEB PC-based programming tool.
