TOPGREENER Humidity Sensor Fan Switch for Ventilation with Wall Plate

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

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.

The automatic humidity control sensor works BUT, once you turn the fan on manually it erases the programming and the switch has to be used manually from then on or the fan will never turn off. 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.

I ordered two of these for a remodel to clear out steam in a kids bathroom after they stand in there until the water run cold. Read the instructions and it works great. The key is to let it do its job or if you turn it on, dont turn it off. It will turn off automatically. Had an issue where one was running excessively and they sent me a new one without any issues. Very happy with product and customer support.

We have a approximately 25 sf sperate shower space. Even at it's least sensitive setting it will continue to cycle for 3-4 cycles. I'm going to install a plain old timer switch.

Easy to install and working great! Thanks!

Replaced an existing fan switch. Easy to install. Fits perfectly in the existing cover plate. Set to medium humidity setting. Fan comes on within a minute of turning the shower on, even if I don't switch it on manually. Automatically switches off when humidy drops. Illuminated switch is a nice touch.

I am very satisfied with this humidity sensor switch, easy to manually select and it will also turn ON or shut itself OFF. I have had it turn ON while showering, and afterward I walk out to my bedroom to dress it has continued to run until it senses it should shut OFF. It has a nice decorative style. I finished the dual outlet, one for the lighting over the mirror, with a screwless cover plate. It is things like that that make my small bathroom much like having a spa at home.

Good product but would not work in my application

Working perfectly as expected. Comes on automatically when needed, turns off by itself when its done. Really like it.

Although the scary reviews. I decided to try my luck and ordered 2. came on time. very easy to assemble and configure and working fine. however sometimes yes turning on might be delayed but its OK. I don't expect 100% accuracy of few dollars sensor. the sensor light is very bright so its better to shut the bathroom door in case the switch is facing the door. Cheers !

Le programme est facile a faire. par contre, la detection d'humidité n'est jamais bonne. des fois ca démarre sans que l'humidité soit élevé. des fois le contraire. Humdité élevé mais il ne fonctionne pas. mode manuel 30 min. ca ne fonctionne pas non plus. il reste allument tout le temps

Had to rewire but finally installed unit and it is working as advertised. Set Humidity to High, again, took a few time to get it right, but in the end, all is working.
