It looks like the OP got "hack attacked" by getting a condenser swap w/o the matching air handler. Happens a LOT. Heat pumps are very sensitive to having the correct air handler and the installation must be done correctly. Ecobee thermostats let the installer choose how the thermostat handles temperature lag, time, temperature, or both.

Tom, I'm curious to know what smoking gun you are referring to. The link you provided is to an article on running heat pumps vs. auxilliary heat.

James: just read further down the above page, or do a control f for honeywell problem. thanks! t

Tom, Good discussion out there regarding each and every temperature control problem in Heat pumps. Well, I do have a experience that heat pump handle temperatures well below 30 without having to resort to AUX or EMG heating.


We're talking here about 2 things: how a thermostat controls a heat pump, and whether a thermostat controls on temperature or CPH(cycles per hour). Please read down the cited page to get to:" No, Honeywell does not do the swing.. the CPH would need to be changed. I know they say 9 for electric heat strips, but I always suggest seting it to 3, and you get a much longer run time and down time."

Since everyone knows about Hwell & Nest , which I believe control only on CPH. I'm going to install a LuxPro PSPU732T plus temperature sensor($100), which also controls only on CPH, but I can't afford an ecobe, which controls on temp!

Tom
