please help! What should my CORRECT ambient air be at?

[Luvyna]

Thank you thank you thank you.

So my ambient air is okay? It’s normally 79 on his hot side and 76ish on his cold side. Everything else seems fine, his humidity is 60 normally. What’s the temp the ambient air should NOT go under. I’m going to keep the CHE for the colder nights.

Yes, your range is fine. The minimum ambient air temperature is 75F but it's preferable to have your temps at least 1-2 degrees above this. And as mentioned before, make sure you are using a thermostat with both your UTH and CHE!
