Siemens Building Technology 540-520B Sensor 320734-701 its compact footprint and clearThe Siemens 540 520B Room Temperature Sensor is a dedicated sensing solution designed exclusively for use with Siemens Terminal Equipment Controllers (TEC). This analog room sensor provides reliable HVAC zone control within a standard setpoint range of 55F to 95F (13C to 35C). Engineering focus on the 540 520B centers on its RJ 11 connection, which enables a direct "plug and play" interface with PXC Compact and Apogee automation systems. This non
