Honeywell 190097C 3 Speed Control Switch
Four-Position Wall Switch
Using this optional, wall-mount control you can conveniently change fan speed without reaching overhead for push-buttons on a ceiling-mounted air cleaner. Push buttons let you select High, Medium or low fan speed, or off. By varying the speed you control the rate of air cleaning as the indoor air quality changes throughout the day.
Control switch for F57A/B, F90A, F59A, F70C. 3 speed.
