Resideo 123773A Sail Assembly
The Resideo 123773A Sail Assembly acts as the critical sensing element for the S688A Sail Switch, providing reliable airflow detection in both vertical and horizontal duct configurations. This replacement sail assembly is designed to actuate the switch when duct velocity reaches the required feet per minute (FPM) threshold, ensuring that auxiliary equipment like humidifiers or electronic air cleaners only operate during active blower cycles. The 123773A is functionally identical to the 123773A/U and is engineered to withstand the constant static pressure fluctuations of light commercial and residential HVAC systems. Proper sail switch installation requires precise alignment within the center of the airstream to prevent mechanical binding. This HVAC airflow sensor component is essential for preventing equipment operation during low-flow conditions, protecting the heat exchanger and improving overall system safety. Integrating this OEM Resideo part ensures the mechanical linkage maintains the correct sensitivity for low-velocity applications.
Key Benefits- Direct Compatibility: Engineered specifically for the S688A series sail switch, ensuring proper mechanical throw and pivot alignment.
- Versatile Duct Orientation: Capatible with both horizontal and vertical-up or vertical-down airflow directions for flexible field application.
- Low-Velocity Sensitivity: Formed to catch light air currents, facilitating reliable equipment interlock in variable speed systems.
- Industrial-Grade Materials: Constructed to resist corrosion and fatigue caused by constant cycling within the plenum.
Is the 123773A compatible with the 123773A/U model?
Yes, those two part numbers represent the same technical specification and are interchangeable for all S688A series applications.
Can this sail be trimmed for smaller ductwork?
Standard practice allows for minor trimming to avoid contact with duct walls, though significant modifications may alter the airflow detection threshold required to close the switch contacts.
Why is my sail switch not engaging despite high airflow?
Ensure the 123773A sail assembly is not rubbing against the duct cutout and verify that it is positioned in the center of the airstream where velocity is highest.
