Siemens Building Technology 540-660B TEC Room Temperature Sensor

The Siemens 540-660B TEC Temperature Room Sensor is a digital read out that will measure and display the temperatures inside. The sensor uses an Ohm Thermistor as its sensing element and measures variation in ambient temperature. This data is processed and shown on a transparent liquid crystal display. Precise temperature regulating can occur because the control unit of the HVAC system can communicate with the sensor. The Siemens 540-660B are the main applications for the HVAC systems in homes and businesses. It is capable of controlling heating and cooling outputs based on the detected room temperature seamlessly, using Terminal Equipment Controllers.
