Description
The Honeywell C7021P2004 Small Metal Button Sensor is an NTC Type II 10K Ohms temperature sensor used to measure temperature changes with accuracy in HVAC systems. It converts temperature variations into electrical resistance values, allowing compatible control equipment to monitor and regulate operating conditions. This is commonly installed in air handlers, rooftop units, chillers, heat pumps and other control equipment where temperature feedback is required. Within the system, it provides input to the control board, supporting stable temperature regulation, efficient operation and consistent system performance.
