In my previous house, the v1 prototype was wired straight to the boiler as there was no previous thermostat. In the current house, the v2 is wired to the Honeywell, so one can override the other as they are in parallel.
It was pretty finnicky stuff and I had to scour the internet for decade old wiring guides, but I like that sort of thing so it was good fun.
Every solution is a good solution if it makes your life easy and you have fun installing it!
If you find dismissal of your inability to coherently explain the concept you brought up rude, that’s your prerogative.
You’ve said enough to demonstrate you don’t understand basic empiricism, have not done sufficient reading on the topic that - again - you brought up, and have contradicted yourself in your own comment.
You are dishonest, and we’re pretty much done here.
