Description
The York S1-L4064B2210 Fan & Limit Control regulates blower operation and monitors temperature to support safe and efficient heating in HVAC systems. It is designed to detect high- and low-limit conditions and therefore to turn the fan on or off to ensure the correct airflow and system stability. This provides proper coordination to burners and limit switches to prevent overheating, or short-cycling. It assists in keeping the airflow balanced, the temperature constant, and the operation secure to keep the heating performance efficient.
