Siemens Building Technology QAC2012U Temperature Sensor What is the difference betweenThe Siemens QAC2012U is a professional grade 1000 ohm platinum RTD outdoor temperature sensor designed for demanding building automation systems (BAS) and HVAC operations. As a direct replacement for TE 6323P 1, this unit provides the precise outside air temperature (OSA) data required for critical control logic such as outdoor reset, chiller optimization, and economizer cooling. Featuring a Pt1000 sensing element with a 385 alpha coefficient, the
