Where I’m at, the temps flip-flop day to day, even hour to hour. In the morning it’s 35° outside, and by evening it’s 79°. I gave up keeping up with the temps and shut my unit off for the time being.
My question is why can’t HVAC units be programmed to say that if the outside temp reaches n° and the inside temp reaches m° cold, turn on the heat; conversely, if the outside temp rises to n° and the inside temp reaches m°, then turn on the AC?
My thermostat already knows the outside and inside temp, but I still have to manually switch it back and forth. I want a system that I can just set it and forget it all year round.
What kind of sensor do you suggest for measuring that? I’m genuinely curious why they are not industry standard.
My guess is price and/or robustness. The RTCs we use are cheap and durable.
Truly It’s not my line of work so I’m not going to start randomly recommending products, I don’t think it’s fair to talk out my ass hahaha
What I can say however, is the reason I was so bold in my assertion previously, was that I personally do a lot of hobbyist electronics, and wiring up temperature sensors is very simple. It’s very much a trivial aspect to basic circuitry, because heat is such an aspect. It’s in your most basic things from coffee pots to hair dryers but even down to smaller electronics, bulbs and projectors, everything really in its own way.
And then my father was a highly trained meteorologist with the government of Canada for 43 years and then another 10 of consultancy, they scouted him because he was the 100% in all courses math superstar at his university for his year.
My father taught me a lot about how heat is measured and it’s a huge concern in a way that the average weather watcher doesn’t understand. It’s talked about in Watts per Square Meter. So that could be how much heat a structure may absorb per square meter, or perhaps how much heat is dissipated per second in a certain wind.
That’s a major and primary concern of anyone in the agriculture industry, think for example a farmer that holds a barn full of cattle, he absolutely needs to know how much heat that building’s going to dissipate so he can plan for heating.
But it doesn’t end there, it goes into so many different areas where heat is an issue, and weather is the primary driver of heat transfer.
So I guess in summary, a solution is trivial, I’m not sure if there’s an official product, but we’re not talking rocket science! Edit: I guess in a way it’s pretty cool and it’s pretty complicated, but the thinkings has all been done by people smarter than me I’m just saying it can be put together and lots of people probably do this every day.
Edit2: I guess also my brother-in-law was a graduate of 4-year electronics program and he ended up working at our local eh price where he designed some forms of heating control systems but to what degree I know not. We talked a bit about some of the egghead stuff so I think in summary it’s doable.
