Description
The Resideo 123773A Sail Switch Assembly is a component that is used to detect airflow for better performance of the HVAC systems. It operates when air flow turns the internal sail. In the process, the sail moves and closes an electrical circuit to indicate the presence of the air passing through the duct. This is normally applied in furnaces, fan coil units and air handlers to ensure the system is in better working condition. It is small in size, which makes it easy to install, enhancing safety as it will not allow equipment to operate without proper ventilation. This switch improves the performance of the system, the durability of the working components and provides durable control of the condition.
