Ecobee Settings for Heat Pumps with Resistive Aux Heat

I’m in the process of replacing a old radiator system with a centrally-ducted, air-source heat pump system with electric resistive backup heat. I’ve found that the default ecobee algorithm seems to behave surprisingly poorly for this system, and wanted to write up some of the settings that I’ve found yield better behavior.

A disclaimer. I’m not an HVAC professional. I have two decades in software operations, a background in physics, and far too much experience inferring system dynamics from timeseries graphs. This advice may void your warranty, burn your house down, etc.; everything you do is at your own risk.
