Description
Ensure your HVAC system responds precisely to airflow with the Honeywell/Resideo S688A1007/B Sail Switch—a rugged, reliable component engineered for performance. Perfectly suited for electronic air cleaners, humidifiers, and other equipment that require activation only when air is flowing, this sail switch mounts directly in the return air duct to monitor unrestricted airflow and trigger controls accordingly.
Features:
- Simplified installations with multi-speed fans, inaccessible air handlers, fan motors with voltage or phase different from controlled equipment; eliminated wiring to system fan.
- Polyester film sail mounted on a micro switch snap switch.
- Removable spring counterbalances sail to allow mounting in either vertical (up or down) or horizontal air flow.
- Top and bottom conduit knockouts for wiring convenience.
- Low air velocity switch operation makes at 250 fpm and breaks at 75 fpm.
