Review on BAYITE DC 12V Digital Temperature Controller 🌡️ with Sensor and 1 Relay - Fahrenheit, 10A by John Butler

I built a standalone solar hot tub and used two of these to turn a 12 volt water pump on at 120 degrees and off at 104 degrees to add water heat. It freezes here a couple of times a year and the manifolds are PVC so I used a second controller to turn the pump on at 35 degrees and off at 50 degrees to keep the panels from freezing. Both worked great. I was concerned about the way the manifold temp sensors were installed so I contacted the company. They were VERY helpful and sent an extra sensor in case I break one during installation. If there were more than 5 stars I would tick them all.
