Application
The C7100C1003 is designed for use in commercial and light industrial HVAC systems where accurate duct air temperature sensing is critical. Its averaging design ensures the controller receives a representative temperature reading across the duct cross-section rather than a single-point measurement, improving system efficiency and comfort control. The recessed quick-connect terminals simplify installation and reduce field wiring time.
