Siemens 540-520B - Siemenstype Sensors and Room Units

The Siemens Flush Mount Room Temperature Sensor is a 10K ohm, self-contained, non-intrusive, and tamper-resistant unit used with Terminal Equipment Controllers (TECs). The sensor connects to the RJ-11 port of the controller via a pre-terminated cable. This unit has a stainless steel cover. This sensor provides superior thermal isolation from interior wall conditions. It is designed for applications in which a standard room temperature sensor is not aesthetically acceptable or where there is a security issue.
