Product Description
Siemens QAA2212.FWSN is a wall-mounted room temperature sensor that uses a 1 kOhm platinum RTD (385 alpha) element for HVAC and building automation applications. The unit provides RTD resistance output and field-selectable analog outputs, an integrated display with setpoint adjustment and override, and ships with installation hardware. It operates from 18 to 36 Vdc or 24 Vac ±20% and measures approximately 2.75 x 1.5 x 4.5 inches, weighing about 9.6 ounces.
- 1 kOhm platinum RTD (385 alpha) sensing element with RTD resistance output and selectable analog outputs (0-5 V, 0-10 V, 4-20 mA).
- Integrated display, setpoint adjustment and override; configurable OLED/readout for room conditions and set point.
- Wall/surface mounting with included installation hardware; terminal block connection; enclosure rated NEMA 1.
