## Features

- Auto Humidity Activated Operation - Sensor switch detects excess humidity and automatically turns the ventilation fan on. Once activated, the fan runs for a fixed 20-minute cycle, helping to avoid unnecessary operation and save energy. Perfect for high humidity locations such as the bathroom, laundry room, basement, etc.
- 3 Adjustable Humidity Levels - Equipped with three adiustable gears, covering a full humidity adiustment range from 45% to 80% RH, vou can select the proper setting to match different indoor spaces and daily use scenarios.
- 20-Minute Time Delay Operation - This controller adopts fixed 20-minute running interval design. No matter manually or automatically turned on, the fan will run for 20 minutes steadily. If the humidity is still high after timing ends, it will pause for 5 minutes and restart another 20-minute working cycle to avoid motor overheating.
- Manual Control - Features a manual ON/OFF switch to bypass the humidity sensor. Manual ON runs the fan for 20 minutes then auto shuts off. When the manual button is used to turn OFF the fan, the fan will turn OFF immediately, and the humidity sensor will stop detecting humidity until it is reset by the user. This is a great feature if you live in areas with very high humidity and you don’t want the fan to come on throughout the night.
- Reliable, Code-Compliant Operation - Neutral wire required. One decorator wall plate included. Single-pole use only. It supports 120VAC power and a maximum 3A fan load, making it compatible with most standard bathroom exhaust fans. Meets California Title 24 and IECC 2021 requirements for bathroom ventilation controls. Comes with 3-year warranty and is UL-Listed.
