The Honeywell S688A1007 sail switch activates an electronic air cleaner, a humidifier, or other equipment in response to airflow from the system fan. The S688A is mounted in the return air duct where the sail will be in the direct path of an unrestricted air stream.
Features
The Honeywell S688A1007 includes simplified installations with multi-speed fans, in- accessible air handlers, fan motors with voltage or phase different from controlled equipment; eliminated wiring to system fan. The
polyester film sail is mounted on a micro switch snap switch and the removable spring counterbalances sail to allow mounting in either vertical or horizontal air flow. The top and bottom conduit knockouts ensure wiring convenience. Low air velocity switch operation makes at 250 fpm and breaks at 75 fpm.
