The C7750A is a direct wired temperature sensor that is used to sense discharge or return air in a duct that may be controlled by an Excel 10 Controller. The C7750A Sensor consists of a temperature sensitive 20K ohm thermistor that is connected on a circuit board to two linearizing resistors in series‑parallel configuration.
