Neutral wire required. UL listed. White, 2 Pack: Accessories - desertcart.com ✓ FREE DELIVERY possible on eligible purchases Review: Incorrect programing instructions - Installed this humidity sensing switch replacing a really old school fan timer in our laundry room that had an analog clock in it with metal tabs to set time intervals. Installation was simple and wired up exactly as the old timer. Tested it by blowing on it and it immediately turned the fan on when sensing humidity from my breath. The instructions that came with it for programming are totally incorrect and mention being able to set the time for how long it runs, which is not possible. After researching this I actually found the correct installation guide online which states the time is runs is always 20 minutes and is not adjustable. You can only adjust the humidity sensitivity to three preset settings and that's it. Programming: - The fan button will be used for programming - Pay close attention to the LED lights as it will flash to indicate successful programming steps and each time the button is pressed while making selections. - After each step, there are only 20 seconds to make the next programming selection. If a selection has not been made, time will expire and the LED light will flash 3 times and exit programming mode. There’s only one Programmable Function Function 1: Humidity level (Humidity Range 45% 65% 80%) - Setting 1: Low humidity sensitivity 45% (requires little humidity to trigger) - Setting 2 (Default): Medium humidity sensitivity 65% - Setting 3: High humidity sensitivity 80% (requires high humidity to trigger) To program the humidity sensor, you must first enter programming mode: STEP 1: Enter Programming Mode Press and hold the fan button for eight seconds until the LED indicator comes on. STEP 2: Choose the Setting Press the fan button the same number of times as the Setting Number (For example: Press the button 2 times to select Medium detection 65%). After the last button is pressed the sensor will flash back the current setting for that function 10 times at two-second intervals. If no selection has been made, the device will exit programming mode. STEP 3: Save the Settings Press and Hold the fan button for eight seconds. The LED light will flash 3 times. indicating that the settings are saved then the load will turn OFF. Example: Change to Setting 3 (High humidity) 1. Press and hold the fan button for eight seconds until the LED indicator comes on 2. Press the fan button three times. The LED indicator should now blink three times every two seconds 3. Press and Hold the fan button for eight seconds. The LED light will flash 3 times indicating that the settings are saved then the load will turn OFF Review: The switches work well - Great little humidity switches. Programming is easy and is well laid out in the manual, and they seem to function well. They look nice and wired in easily. Good value at $43.19 for two, they were around $35 each at my local Home Depot. Note that they do require a hot (black) neutral (white) and ground (green or bare) to wire in. My original switches were not wired that way but luckily the connections I needed were in there folded back. Simple DIY that protects from mold and saves my kids a step every shower. Before and after pictures attached, I found new wall plates at Home Depot for around $2.50 each. ## 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.

The instructions clearly state that there is only one programming function-humidity level. Then, in the next paragraph it explains how to change the auto-off timer from 10 seconds to 20 seconds. Maybe things have changed since I went to grammar school but in my book that's TWO programming functions. Perhaps the conversion from Chinese to English text is the source of the problem. Anyway, the humidity sensor on this thing is worthless! Could have simply bought a time delay off switch for less than half the price. ## Frequently Bought Together - TOPGREENER Humidity Sensor and Fan Control Switch, Ventilation Fan Humidity Sensor Switch, Fan Switch, Neutral Wire Required, TDHS5, 2-Pack - ELEGRP Occupancy Motion Sensor Light Switch, PIR Infrared Motion Activated Wall Switch, No Neutral Wire, Single Pole for CFL/LED/Incandescent Bulb, with Wall Plate, UL Listed (10 Pack, Matte White) - ELEGRP Digital Dimmer Light Switch for 300W Dimmable LED/CFL Lights and 600W Incandescent/Halogen, Single Pole/3-Way LED Slide Dimmer Light Switch, Wall Plate Included, UL Listed, 10 Pack, Matte White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/469054235-topgreener-humidity-sensor-fan-switch-for-ventilation-with-wall-plate](https://www.desertcart.fr/products/469054235-topgreener-humidity-sensor-fan-switch-for-ventilation-with-wall-plate) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-09-14*
