Review: Affordable, useful thermostat - This item I have used in 2 applications. As an electronics cabinet temperature monitor/switch where it switches on fans when temperature rises above 80 ° Farenheit. It switches off at 84.8 ° F reliably. The other application is freeze protection 32 ° energizes pipe tape heaters and heat pads. The digital readout is bright and easy to read up to 10 ft away. There are several wiring options that can be found online by searching product and exact model#. I used a direct 12 V dedicated positive lead, and negative lead. Jumpered the 3rd and 4th terminals to secondary negative lead which I also incorporated a manual switch, so I can isolate it if I need to. For mounting I used sheet metal in one app, and plastic in another. Traced the outline with sharpie then carefully cut inside the line with shears and jigsaw respectively. Its an affordable useful item, been using for a month now.
Review: I N F O ... Y O U ... M U S T ... K N O W ... B E F O R E ... B U Y I N G - I purchased the same controller from 2 different sources. On one order I received the old design and on the other order I received the new design. The one I bought from (DZS Elect) was the NEW design and included an operating manual. It worked great for 3 days; but then failed and only showed LLL in the red digital display for the current temperature. I checked the probe and the wiring. The failure was internal in the controller. The NEW design controller uses surface mount rectifiers on the pc board next to the relay. Do NOT buy the new design from (DZS Elect). I bough the other controller from (Xipshow) and the controller I received was the OLD design (which is much better than the new design). The old design uses redial lead rectifiers in the pc board next to the relay. but it does not come with the operating instructions. You can get that by going on line and looking up KETOTEK Model KTF0091. It's only one page. In almost every case you can use the factory settings for operation and only change from C° to F° if that is your choice. The important point is this ----- Buy from (Xipshow) and get the OLD design. It works great with no problems.

### ⭐⭐⭐⭐ Good that they come in 2's
*by G***T on December 22, 2022*

I got these to run cooling fans on a RF amplifier. The first one I hooked up only lasted about 5 minutes, in fact while I was programming set points it suddenly just went blank, was wired correctly, no shorts, no smoke, it was dead. So, I hooked up the second one exactly the same way and crossed my fingers. Yeah, this one works better. Another thing I didn't like is that you can only program one setting at a time and if you're too slow it goes out of program mode and you have to start all over. Other than that the one is still working fine after a week or so. As far as accuracy I'm not worried if it's a degree or two off, I just want it to work right to keep my amplifier at a decent temperature while operating. I ran a separate power supply, one for the controller and one for the fans. The power for the controller is from a regulated 12.2 volt power supply and the other for the fans comes from a regulated 24 volt power supply.
