Siemens Building Technology 540-652A Sensor R-134A For technicians managing energy-conscious facilitiesUpgrading or maintaining Siemens field panels requires precise sensing hardware. The Siemens 540 652A Room Temperature Sensor is a high performance interactive device designed specifically for Terminal Equipment Controller (TEC) applications. As a veteran in the field, you know that accurate site data is critical; this unit utilizes a highly responsive 10K ohm NTC thermistor to provide stable room temperature monitoring across a range of 55F to 95F
