I use these on many little projects that require a thermostat. Easy to wire, extremely low idle draw. Easy to adjust. Great for the money!

I used it to control auxiliary cooling fans on a vehicle. It was a little tedious to set up the case that comes with these, and they're set up for pretty small wire. I used the 2 thermostats to get high and low fan speeds using 3 external relays, since my fans draw more current than the units are rated for. The attached picture shows it with all control wires assembled for my application.

I have some older firmware versions of this thermostat (settings only go from P0-P6) and the P5 setting (delay start) only works once when the power is applied to the thermostat but no delays afterward.In this order, I received the newer firmware (settings go from P0-P8). The delay start setting works repeatedly this time. However, the P5 setting appears to be in seconds (not minutes). I can set the P5 delay start value from 0 to 600 seconds. The delay start feature appears to work in both heating and cooling modes (set by P0).In my application, I'm controlling a compressor type refrigerator. When the compressor is turned off, it must rest for a minimum time before it can be re-started. The delay time (setting P5, now in units of seconds) ensures the minimum compressor rest time.I like the included case with these thermostats. Now that I know the delay start time works, I will definitely be buying more of these thermostats.

I used this product to control a silicone windshield wiper heater strip rated at 50w 4.2amps. The other one will be used to control a 12v cpu fan to provide air circulation inside a 12v portable freezer/refrigerator. Instructions were bad as usual but I finally figured out the settings. One of the acrylic cases arrived with broken parts. These have very small nuts and screws and assembly will take good eyesight. Recommend using a dab of hot glue or Elmer’s glue on each nut once you get it put together to keep them from falling off and rolling under the refrigerator. The 4 power block terminals are very small gauge and the screw heads which grip the wires are very soft metal. Solid core bell wire fit nicely but stranded wire is almost impossible to use unless you just solder it to the terminals. Overall it was a pain to get them put together and do what I wanted them to do but they work and the two pack with cases is a good value. If the people who sold me this item read this review, you owe me a case.

The microchip couldn't handle it's own relay when the temperature got low enough to turn on so I tried the second one that came with it and something similar happened with it to but with the second one I didn't hook anything up to the relay I just connected the controller to a 12 volt power supply and triggered the thermostat with a heat gun to see if it would work and the moment it detected a warm enough temperature to turn the relay on it blew a microchip and wouldn't even show anything on the display much less function at all.... Very disappointing 🙁

Okay, you get 2 circuit boards with no documentation and if you're like me you didn't read the fine print and you're going to have to deal with degrees C. Whatever. It's a good price and it works. Plug in the thermistor, and power it up with 12vdc (that's labeled at least). The display is pretty bright and mine was set at 50C (122F, that's a hot set point). Hit the set button, then tap the - button about a million times to get it down to 30C, or something reasonable, and hit set again to save that setting. Now, assuming your room is below 30C (sorry for you if not) then grab the thermistor and watch it sail up to 30, 31, ahh 31.7 then click, the red led comes on and the relay closes. K0 and K1 are floating - they are not tied to anything, so it's just a set of contacts that closes. I figured they would be tied to the 12 vdc supply, but no. Not a big deal, just a couple of jumpers and we're in business. Anyway, would a schematic and some basic instrutions been too much to ask for?
