I have yet to see a picture of a thermostat in your sub-thread.
Go back to the "dial thing" you referred to earlier and take a picture of it...
Cheers!
The entire assembly is the thermostat and display, the transformer is part of the assembly and reduces voltage for the components on the display and electronic thermostat. The schematic makes things pretty simple. We have red wires and we have black wires, we have a board with buttons and a display. When removing the entire assembly there should be 3 red wires and three black wires, plus two blacks to the sensor which are probably smaller or of a different appearance. We also have a member who really has absolutely no business trying to do this. It's not rocket science, but it does call for someone with at least a rudimentary understanding of systems, and of electricity.
Unfortunately this project requires either tracing wires back and understanding what you are looking at. or testing live power, which is not something someone who is timid or unskilled with electricity should be doing. It's a job that requires hands on help in this case, by someone with some knowhow... that cousin, brother in law, neighbor, etc who knows what he is doing and how to do it safely, and without destroying anything. Who has the experience to secure everything before testing and to wear dry leather gloves. Who doesn't need to be told that the green wire can be used to determine which wire is hot, and the hot wire can then be used to identify the neutral (of the other color).
It's a simple job, and one I made the mistake of assuming anybody should be able to tackle, but I come from a different generation where "can do" was the norm. Where we grew up doing things people today would consider irresponsible and dangerous. I've been playing with things electrical for over 50 years, I've built my own boats and bicycles, and quite a few vehicles and machines of various types, rebuilt engines and transmissions because nobody told me I couldn't. Built inverters (not from plans, but from an understanding of the principles) so I could buy 3 phase equipment. I've built and flown my own aircraft. I've been caught in rip tides swimming off the coast of Kauai and Oregon a number of times, and made my way back on my own safely. I have hiked and backpacked for long distances (max 250 miles in one trip), often in bear country without carrying any "protection", kayaked in white water, etc. I've worked with and owned drilling rigs, handled explosives, hunted and fished, etc. I've done lots of plumbing and electrical work, built buildings. I can fix a well, dig in a septic tank and drain field, fix a leaky roof, assist a lamb or calf being born......... or any other animal probably, fix and operate about any kind of heavy equipment from a backhoe or excavator (I've owned both), to a scraper, rock crusher, crane (I own one now), large loader or forklift (I own both), rebuild a gas or diesel engine of any size (largest was a D8 Cat engine), and I began brewing beer and wine in 1969 (approximately). I tend to assume most people experiment with many things while growing up, but we seem to be transitioning into a society of specialists of ever narrower focus. For example, the electricians I know specialize in AC and are lost working with DC... which makes no sense to me. People in the construction trades do framing OR roofing, OR hang and finish sheetrock, insulate, OR pour concrete, OR do finish work, OR paint........ and seldom cross the lines. People who cook for a living usually can't fix their own car, deal with plumbing, or electricity. Carpenters don't understand structural engineering, and engineers don't understand carpentry. Mechanics follow flow charts blindly, with zero understanding of systems. And more and more people are doing work that I simply cannot understand as "work"....not producing anything identifiable as a product....... I seem to have become an anachronism. My good friend who is also a welder......but unlike me is ONLY a welder often chides me for my "do it yourself" mindset. "Do what you are good at and hire someone else to do that" is his frequent refrain..... and his mindset, which is carved in stone. I wasn't raised that way, and haven't lived that way. My friends, neighbors, and customers are farmers and ranchers, most of whom think the way I do........
