Since it’s a heat pump, the ability to heat the inside depends on the outside temperature. Warmer outside, faster to heat inside.
But there’s no way to tell the system - I want 72 at 8am, you work it out. So I need to see if tomorrow morning will be 30 or 50 outside and set the start time accordingly. That’s not smart.
Heat pumps aren’t great at large changes anyway, but even 68 to 70 or 72 would work for me
And I also want that inside temperature to be based on the rooms I expect to use at those times: Night time, bedroom. Daytime, living room. Ecobee has exactly this function, Trane/Nexia does not
- dashundchen 6y agoHow many degrees below your occupied temperature are you setting back? I have a ground source heat pump and my understanding was to pretty set and forget unless you have multiple zones or are going to be away for a long period of time. Reason being heat pumps have variable speed compressors and setting them back forces them into less efficient higher stages, and as you mention take a lot longer to recover compared to traditional heaters. If the system is sized right it should be running it should be running below max at a relatively stable power.
- maxerickson 6y agoThat's what I meant by using it more. If you just set everything to 72, then presumably the rooms will be that temp when you use them. Doesn't help if you want to sleep at cooler temps of course. This would be a pretty reasonable approach in a building with high levels of insulation and efficient heating/cooling.
