Electronic Thermostat Controller, DC 6-30V 24V Digital Temperature Control Board -50 to +110 Degree Celsius High Accuracy LCD Digital Micro Temp Control Switch Module with Waterproof Sensor Probe

Work perfectly for what I needed. wiring and programming is a little confusing, but some reviews helped with that. I have one hooked up with 24 VDC to run fan when temperature rises to high and the other one in a differnt box to do the same but 12 VDC. The temperature probes are within less than .5 degree celsius of actural temperature. Setting up for cooling: 1. Set letter to 'C' 2. Set bottom number to degrees celsius where you want the fan to turn 'OFF' 3. Set top number to degees celsius in incriments above the fan off set previously. (Example: Bottom number set to 35 and top number set to 2.5 = Fan on at 37.5 and fan off at 35) Wiring for Cooling: 1. Plus Terminal - Connect to Possitive on Battery and Positive on Fan 2. Negative Terminal - Connect to the Negative on the Battery. 3. Relay Terminal - Connect to the Negative Terminal wire. 4. Relay Terminal - Connect to the Negative on the Fan.

Quality seems to be good, and it's easy to configure. Wish it could switch to fahrenheit, but it's not a big deal because you set it and forget it. When you cut power to the controller it retains the settings. We're using it to control a small ventilation fan for the electrical compartment in our camper, and it's been working flawlessly! Small size, great value!

It works as expected. I like the ease of parameter changing and its accuracy. I drive a small 12V fan for cooling my router, so far no problem. I’d rather keep high voltages and/or currents off this board. Utilize an external relay (with appropriate suppression circuitry) for more demanding loads.

Solid unit. Good visual on the LCD screen. Programming good, instructions leave a bit to imagination. Not real clear how to set the hysteresis of the on/off cycle. Light, powers up and stores settings. Handy.

It’s garbage. I’ve tried several different ways to wire it just over 13 V in and on one occasion I saw 2 V out but most of the time I get no power out even though the relay is on. Documentation is garbage as well but that’s not surprising given where it’s from. The picture on the product page is not accurate either for the wiring. Even the screen printed markings on the item itself doesn’t seem accurate. It says V plus and V minus. And two other markings for the load, which is not accurate it does not work.

Works well. I see some comments about failures. I have used it for 2 weeks now and so far so good. I have it wired to a video receiver. The cabinet doesn't meet the recommended clearances, so I bought this to control a USB powered fan. (connectors bought seperately). The wiring isn't completely intuitive. I got out a VOM to understand what the connectors and switch did. To be honest, I then looked at the wiring diagram and it showed the same thing, but I didn't look until I was done. Of note, the USB is 5v, so it does work a little lower than 6. I'm sure others might want a USB powered option.

Very easy to use. There are not a lot of programming steps, which makes it good for quick changes. I am using this to control a greenhouse heating mat. There is a mode (heat/cool) set point Temp, temp range, and alarm function. There is also a serial out for communication. I'm only using the temp on/off functions, so I don't know about the alarm and serial details. The only things, I would wish were different is the temp only reads in C, and the display's light is always on. Otherwise, its great for controlling 120V heater mats with minimum fuss.

Screen is bright and easy to read. Controlled a small 24vdc fan well until the fan failed. Setup is also easy, for basic temp control instructions weren’t even required. For audible alarm they would be needed, but not what I bought this for and this instructions are quite clear if one wanted to use this feature. Can be powered via terminals or micro USB as seen in photos.

Il fait exactement ce qu'il doit faire. Par contre, un peu dur a programmé
