Great working product. But You need to Read wiring diagram.
5 Stars
Great working product. But You need to Read wiring diagram.
I’m a licensed HVAC contractor in California, and I’ve installed 3 of these thermostats for my client. Everything works great. I saw the photos of burned thermostat uploaded by other people here and I can confirm that they improperly wired it. Red wires and black wires don’t mean In and Out. For the 230v you need to connect one red and one black to “LINE”(power from the electrical panel.)! And the second is Red and Black to “LOAD” (here you connect the consumer, thermal element, or whatever ). Please look at the diagram on the back of the thermostat Body, and don’t blame the manufacturer for something you messed up.
Thank you for your feedback
