Fantech PRO Humidity Sensor

PRO Humidity Sensor The humidity-sensor uses a sophisticated humidity sensor that responds to: (a) rapid to moderate (user-adjustable) increases in humidity or (b) humidity above a user-adjustable set-point (50%-100% relative humidity). The humidity sensor may occasionally turn the fan ON when environmental conditions change. Remains ON for a user-adjustable 5 to 60 minutes after humidity has stabilized and is below set-point. Saves energy as the unit runs only for the time required.
