So like I said- builder grade. If you had a company come in to install a system, you can pick from many options and features, like multi stage pumps, variable speed fans, etc. the base models from these companies are “builder grade” because it’s basically the cheapest model they can install in 100 houses they’re building. You can look up your system specs online and also see what other similar models are in the product line. You dont need the most expensive system to have good cold weather performance, but you may not get it on the cheapest model.

Must be a shit model then 🤷

If it’s that specific that it happens at an exact temperature, it sounds like an intentional “fuck you” switch on that model disabling it and not an actual physical limitation.

That’s the lock out temp, you probably have a cheaper/builder-grade heat pump.
