I have about 12 of these temperature controllers working in a greenhouse 100 % humidity some are several years old they are still working . For induction loads I have always used a relay rather than the internal contacts. For resistive loads I have never used the above 4 amps I took one apart and think for high cycle rates the contacts would not survive so use a relay that you can replace as needed.

These little controllers work great. I set one up on a homemade yogurt maker and it controls the temperature exactly where I want it. It gets unplugged when not in use and when I plug it in to start another batch of yogurt, it takes off without a hitch. A second one was installed on my outdoor wood stove when the original controller died. This one is continuous duty and works flawlessly. Great product.

I keep a couple of these on hand for my projects. I have used them to control hot tube temperatures. I used one to control a heating tank and have made paint baking ovens. Use one to control a contactor for high current and it will control large heating elements. I haven't personally used one to control cooling but I don't see it being an issue. It's easy to set the temp and parameters. Great bargain! I will always have one or two on hand.

Easy hook up, I will install in a project box so I can fuse the output. This is very easy to setup also, just one note, the minimum temp delta is 1°, from turn on to turn off. I used it to control the temp in a wine carboy, worked great and I would highly recommend it

So far working great, built a system to turn on 3 12v fans when an area of my basement gets too warm. Wish there was a wiring diagram, but once you know the relays are JUST relays and provide no power from the 12V, you run your own from the power and you're set. Wish there was a way to disable heating relay, but it only pulls 3 watts, so it's okay. Overall not bad choice for regulating temperature with a nice sensor and screen output.
