Siemens Building Technology QAA2212.FWSN Sensor 322027-701 Its zero-cross switching technology minimizesThe Siemens QAA2212. FWSN is a precision wall mount room units designed for high accuracy climate monitoring in commercial building automation systems. Built with a 1k Ohm Platinum RTD (385 alpha) sensing element, this unit provides a highly stable resistance output signal that minimizes drift over time compared to thermistor based sensors. This room temperature sensor features a built in LCD display (Full HMI) for real time local feedback and an
