Smart Dupline® CO2, Temperature and Humidity Sensors w. Display Type SHSUXXXXD • Bus-powered CO2, temperature and humidity sensors • Wall mounting • CO2 measuring range: 0 to 2000 ppm • Temperature measuring range: -20 to 50 °C • Humidity measuring range: 0 to 100 %RH • LCD Display for showing measured values • Touch function to activate back-lighting and change signal type • Low current consumption • Easy installation • Smart Dupline®protocol Product Description Ordering Key SH SU CO T H D TheSHSUXXXXD lineare bus-powered roomsensors forwall-mounting.They are available in different combina- tions of CO2, temperature and relative humidity. The sensors have a LCD display for show- ing the measured values. By activating the touch button in the front the LED backlight is turned on and the signal type to be shown can be changed. The only connection needed for the sensor is the Dupline® 2-wire cable. Several sensors can be multi-droppedvia the same Dupline®2-wire bus, thereby simplifying the wiring to the controller significantly. The address assignment and the setup of the display oper- ating mode are performed over the bus by using the SBWEB/SHWEB PC-based programming tool.
