Use case: I had a car audio amplifier under my rear hatch floorboard powering a subwoofer, I think it had far too many overheating cut-outs until it gave up. I replaced that with a larger amp to now power TWO subwoofers, one remained under the floor and the other is in the open area in the back. I installed a 12vdc brushless fan to blow on the underside of the amp, and when I first got everything running, I noticed the fan is a LOT louder than I had hoped, so I bought this temperature switch. I wired it up so that the power to the fan instead went to the temp switch, then the unit's switched leads supplied the (+) 12vdc to the fan. I changed the settings for this video to show what happens when setting "d" is at 2°F and the target temperature is 73°F ... The amp's temp slowly crept up to [Target]+[d] and the fan kicked on and I watched the temp drop to 72.8°F before the fan kicked off. I then let it cycle through one more time to 75°F, fan kicked on, temp continued to creep up to 75.2°F before starting to fall back down, to 72.8°F and fan turned off. That was proof enough that this thing does exactly what I intend, and I now have it set to kick on at 100°F and run until the temp probe reaches 94.9°F (target = 95° and d = 5). The only complaint I have is that the programming is a little convoluted. I did not explore any settings beyond Target, d, and mode = C (for cooling, opposite of H which is designed to switch on a heater to get temps up when the probe gets too cold). I will update this if the unit fails within the first year of use. Review: Works for radiator fans. - This thing is exactly what I was hoping it was. I installed it as a cooling fan thermostat for my pickup. Of course, the internal relay shouldn't be loaded with an 80 watt fan, so I needed an additional relay to set everything up correctly. It reads down to tenths of a degree. The lead for the temperature probe that came with it was plenty long enough to run from inside the cab on the driver's side to the opposite side of the radiator. I wired it up as a ground side switch to reduce wire counts on long runs. I've probably used 5 "automotive" adjustable electric thermostats in as many years, one of each brand I could find. This setup has so far outlasted 3 of them. Doesn't seem to be as sensitive to voltage fluctuations, has a digital readout, and cost less than $20. Of course, this isn't meant to run an automotive cooling fan, and doesn't have an input for the A/C fan like the others do, and requires more complex wiring. Anyways, can be set to run a heater (on when cold, off when hot), a cooler (on when hot, off when cold) adjustable delta T, adjustable trigger temperature (whole degrees), and a warning for too hot/cold (flashing display, no sound). Also, it retains settings when disconnected from power. Update: 6-15-18 Still going strong, and I’ve had absolutely 0 problems. Works much better than everything else I’ve tried, and I only have it zip tied to the bottom side of the dash. Plenty enough vibration resistance. ## Features - Simplified Design---Easy to set.

I use mine to turn a heating element on/off during the winter to keep a small livestock water tank from freezing. **Q: can the sensor wires be lengthened** A: Simple answers: It uses an 10K NTC sensor that can be lengthened up to 100 feet with 18 gauge (AWG) SHIELDED wire. Up to 10 feet non-shielded. **Q: Can you turn it on and off?** A: Yes. You can turn it on and off. Press the button "Rst" to turn it on/off. **Q: How do I switch between cold and hot mode** A: Just change the HC value. HC=H for Heating Mode. HC=C for Cooling Mode 1.Press SET for 3 secs, HC appears on screen, release SET button 2.Press SET once to enter HC parameter 3.Press UP/DOWN button to select C or H, Press SET once again and back to HC(main menu) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to wire, easy (sort of) to program *by F***E on October 25, 2023* This is exactly as described and worked perfectly the very first time I wired it up.
