Digital LED Temperature Controller Module, XH-W3001 Thermostat Switch with Waterproof Probe, Programmable Heating Cooling Thermostat (12V 10A 120W)

I am using this equipment two weeks now is working well. It was easy to set up excepting that the instructions are not in English but i used youtube to do the adjustment. I am using it on a Iptv Box which in my optinion heat up too much that could be a little cooler in its processing which sometimes buffering too much at times. The short fall of this product i beleive the could have added a power switch on it and up grade and switching on the ouput to reducing the speed when using a fan or even dimming light depending the user choice. I added a power switch for when i am not using the equipment The 12volts output is very strong i will have to buy a Voltage Motor Speed Controller DC 1.8V 3V 5V 6V 12V 2A Adjustable Driver Switch with Speed Control Knob to help with fan speed. Integrating these idea into the equipment could help a all in one control. Over all i am saticfied and would recommend it for projects. So it set at 42.5 degree start and 35degree end. it takes roughly 5 minutes from start to end to cool and cycle starts at 15minutes intervals. i just a tape to hold down the guage for now. I going to put the switch and speed control on the equipment built in as soon as i recieve them. I will update that project when i am done.

This is basically a thermostat, intended for mounting in a panel or machine, setting, and forgetting. Once you know the wiring (which is really pretty intuitive: Rd/Bk to power, Yw/Bk to load), it's super-simple to hook up. Note the the output is actually powered - it's not like some similar units that bring out a normally-open relay contact. This means that the load must require the same voltage as the controller (12 volts, in this case). I like that it comes in a case with mounting ears. Again, it's not intended as a front panel instrument, but it's much less hassle to mount this than one of the similarly-priced board-level thermostats, and it looks a lot more professional too. It didn't come with instructions, but the four-line operating instructions on this product listing are enough, or with a bit of rummaging I was able to locate them on the (Turkish!) web site. Basically, you set an "on" setpoint and an "off" setpoint; if the "on" is higher than the "off" then it's an air conditioner thermostat, and if the "off" is higher than the "on, then it's a heater thermostat. Simple. The two setpoints must be at least 2 degrees C apart. (There's no way to set it read F.) I've had no reliability issues with this at all. Once it was set up, it just works. I noted that one of the question answers mentioned a small battery to maintain the setpoints during power outage. This seemed unlikely to me at this price point (I've done electronic product design for a living), so I opened it up, and it appears that the (unlabeled) processor must have some on-board flash or EEPROM, which would make the setpoints completely non-volatile. Certainly I had no problem during my short-duration tests with setpoints being lost when the power was interrupted. All in all, I find this to be a simplistic, but solid and practical, temperature controller at an extremely reasonable price.

Once you figure out how to set the on and off temps, it worked perfectly Chinese instructions only. Leads are maybe 2” long and wire is hard to strip so plan accordingly.

Stopped outputting voltage after 3 days.

while researching how to build a fan/temperature sensor I found this unit from Amazon! Discovered it was less expensive than buying the parts to build one , plus it came in a mountable enclosure , with the temperature sensor. All I had to do was connect a 12 volt source, and the fan I wanted to use and placed the temperature sensor on the heat sink of my ham radio and it was ready to keep the radio cool ! Only one draw back and it is not a major one, the readout is in Celsius with no way to change it to Farenheit, not a big deal once you understand the temp range you want to set it for......in Centigrade......and when you get it for the price offered , a complete ready to go unit, this became, for me, a minor detail. unit is in use and working exactly like I wanted! Great buy!

This arrived with no issues. There were no markings on what wires (or colors) were for what....It came with no details, just the thermostat switch. I had to use a Chinese language translator to help identify which set of wires was for which part. Other than that, there were no unexpected surprises. The device ONLY uses CELSIUS numbers for the temps, but it's pretty simple to do a conversion. Although it would be much handier if there was a means to select one or the other to remove some of the guess work out of it. (Perhaps there is something if you operate on it - but that would void any warranty for sure) It's been in service for a few months now --- It's connected to a exhaust fan in a large shed which is powered by solar setup. It starts and stops on its own as expected based on the settings I inserted. Note that there IS a draw on the power source....I register about .2amp when it's sitting idle. Although this is a vampire draw, it shouldn't impact a properly setup solar system. I have it coming on when it senses about 80 deg F, and then it will shut off when it drops below 75 deg F. The Thermostat has a TRIGGER (turn on) setting, and a OFF setting. Make sure your OFF setting is low enough not to make it cycle too soon, or it will act like it's never shutting off, and will likely place a strain on not only the electronics, but also what is connected to it. In my case, the cut-off is more for times when the temp in question is fluctuating because it's not getting hot and staying there, rather than once the sun is out full time like past spring when the sun is there all day. At that point, if the temp drops low enough (night time) the exhaust won't run since it won't be needed.

It works , but it’s very hard to understand how to operate it and it seems like you “chase” it around a lot. It’s probably me, but I managed to get it set how I want it , by chance. Price is great so I’m not too upset about it.

Cute little thermometer switch that I am using to turn on/off two small fans behind my refrigerator in my camper. I replaced a failed absorption fridge with a conventional fridge, and the airspace behind the fridge vents outside at the top, a requirement of gas-absorption fridges. So I am using that space to my advantage to keep the coils cooler than they would be in an enclosed space. The only downside, which really isn't, is that if your a Fahrenheit user, you'll have to convert your temps to Centigrade to set the on and off points. No biggie, it works.

Used this unit to control some fans for the vented space behind my absorption fridge in an rv. I aluminum foil taped the temp probe to the upper coils then set the temp to 40C for when the fans turn on. Works great to improve efficiency of these fridges. Haven’t had a chance to test long term durability but I’m happy so far with the functionality.

Fonctionne à merveille

control functions as specified, fair price, temperature sensing probe permits remote operation at about one meter distance, small 0.1 degrees C adjustment resolution, maintains temperature settings when power is disconnected, shows ambient temperature and indicates when load is powered.

I have used these a few times in outdoor weatherproof enclosures to control a 12 volt cooling fan. I haven't had one fail yet. Simple to set up. (Can be used for heating instead of cooling by simply setting the start and stop temperatures appropriately.) My load is only 150 mA or so, so I can't comment how well these would work controlling the full claimed 10 Amps. (The wires seem just a bit thin for this.) It would be nice if the power and load wires were a bit longer, but no big deal.

Could not get to work. Way too large late to return. Learn from my mistakes, buy something better, you’ll thank me.
