HVAC: What's best for cold climates?

Then what do I do when it settles? How do I boost it back up?
Fill it in with more ground. If your builder has equipment still on site maybe hit it now pretty aggressively. Not sure if you still have a frost line.

This brought back a crazy memory. I did a two story addition on a home. The exterior was completed and all that remained was backfilling. My excavator was using a backhoe, the second floor was a sunroom.
The owner and I had many discussions about his crazy dog getting into the construction area. The dog would chase light refractions . He once got onto a freshly glued floor during a Parque floor installation.

Well my excavators backhoe had a broken window and when the sun reflected off it, it looked like a disco . An hour later the owner appeared with a sheepish look.
The dog got into the sunroom and literally ripped every piece of drywall off a 20’ section and 3’ high. He didn’t stop with just drywall, insulation and wiring as well.
 
I turned it back down before bed because it seemed wasteful.
Everything I've read and have been told by HVAC installers is to set it and forget it. They are most efficient maintaining a temperature verse trying to bring it up.

That being said if it's going to get down into the 20s or 30s over night while you are sleeping and then pop back into the 50s by the time you wake up I'm not sure if that rule still applies. Lots of math involved

Agree
That's what I meant by them being wonky. They definitely take time to react to thermostatic adjustments. Like me, they're easily confused 🤔

Nobody lives here now, and the building crew is on another job for 10 days. Turning it down seemed prudent.

Until I learn the system better, it doesn't make sense (to me) to set it at 70 and head back to NJ for a week. I want to understand how I can set it so the propane is a backup, coming on when it is too cold. << Need to learn what that temp is. Based on what I saw last night that temp is below 20F.
 
Heat pumps don’t get confused, but they circulate air at a lower temperature than gas furnaces. That’s what prevents them from recovering temperature quickly. Also, because of the lower temperature, you don’t want to use a 2 speed fan with a heat pump, the way you can with a furnace. That further limits fast recovery.

Setting the thermostat back every night is not gonna work well. Setting it back for a week will save some money but you’ll want to schedule your thermostat to reset more than a few hours before you return. Backing up the heat pump with propane instead of the electric furnace is also a good idea. I thought some new heat pump systems are installed with only a gas furnace instead of the electric one.
