Based in Orange County, California, our team specializes in the design and production of high-quality lighting controls, wiring devices, home automation, and smart energy management solutions to better improve the everyday lives of our customers. A sensor switch in a class of its own, equipped with both PIR (Passive Infrared) motion and humidity sensors. Perfect for bathrooms, laundry rooms, spas, or any other room with high humidity levels, the TDHOS5 will help make your space more comfortable and energy-efficient. The humidity sensor works by detecting moisture in the air to automatically turn the ventilation fan on or off based on the moisture level. Automatically turns on when humidity levels are high and off again when they have returned to normal Turn it off again after 20 minutes or when humidity levels return to normal, whichever comes first. Humidity Detection Works by detecting the levels of moisture in the air and turning the fan on when humidity is high. A: Please follow the user manual inside the box for detailed wiring instructions. After set up, the humidity sensor switch detects excess humidity and automatically turns the ventilation fan on. A: The LED indicator will turn solid red when excess humidity is detected. The LED indicator will stay white if the manual button is used and no humidity is detected. During programming, the bi-color LED light will flash once every 2 seconds indicating the current setting is High, twice every 2 seconds indicating the setting is Medium, and 3 times every 2 seconds indicating the setting is Low. A: Press and hold the fan button for eight seconds until the bi-level LED light comes on. The sensor is now in programming mode. Press the fan button the same number of times for that function (For example: Press the button 2 times to select "Medium Humidity"). Press and hold the fan button for eight seconds. The bi-level LED light will flash 3 times and turn to white indicating that the settings are saved and the load will turn OFF. A: Check if the device is wired properly. This device requires a NEUTRAL wire for operation. Often the WHITE wire is used as a LOAD wire. Be sure to test ALL wires. Also, make sure that the HOT and LOAD wires are not reversed. If the humidity sensor does not turn on the fan. Change the humidity level to match the appropriate condition or manually turn ON the fan, after 20 minutes the humidity sensor will be operational. TDHS5 TDOS5-JM TSOS5-KM-W-2PCS TDHOS5 TDTS5 TDTOS5 ## 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.

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 successfulprogramming steps and each time the button is pressed while making selections.- After each step, there are only 20 seconds to make the next programmingselection. If a selection has not been made, time will expire and the LED light willflash 3 times and exit programming mode.There’s only one Programmable FunctionFunction 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 ModePress and hold the fan button for eight seconds until the LED indicator comes on.STEP 2: Choose the SettingPress the fan button the same number of times as the SettingNumber (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 settingfor that function 10 times at two-second intervals. If no selection has beenmade, the device will exit programming mode.STEP 3: Save the SettingsPress 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 on2. Press the fan button three times. The LED indicator should now blink three timesevery two seconds3. Press and Hold the fan button for eight seconds. The LED light will flash 3 timesindicating that the settings are saved then the load will turn OFF ### ⭐⭐⭐⭐⭐ The switches work well *by on Reviewed in the United States July 29, 2026* 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. ### ⭐⭐⭐⭐ Works but has limitations *by on Reviewed in the United States January 26, 2021* I bought this to replace a wifi switch that was being triggered by a wifi humity sensor.It works fine on the default setting.When set to be more sensitive, the results were not what I expected - seemed to fail and eventually I set it back to default.IF you manually operate the fan switch,THEN let it run through the timed circuit (20 mins I think) if you manually turn it off, I THINK that may where we run into terrible and messes up the settings for auto sensing - MAYBE I am wrong - I haven't figured that out. We found it to work better if you use it manually then let it shut itself off.My understanding is IF it runs for 20 mins and the humidity is still high then it will shut off for 2? mins and then turn back on (maybe it's 5). I don't know why they designed this cycle. Sometimes it runs 20 mins turns off for a short min and then turns right back on.I found that you can breath on it to trigger it on too. Why breath on it ? I was just goofing off.I don't think this design qualifies for a 5 star rating but it's a good 4 - the instructions could have been written much better - I wasn't able to find out what the RED light means when it's on or cycling in the automatic mode. Maybe it says so in the instructions -All this said, I have been in home automation since the early 2000's and settled with this switch rather than trying to use a smart switch. I didn't find a great solution and this was my compromise. I may try another name brand to see if I can get better results.
