We've got a ten-year-old Carrier Infinity control that's programmable but is just old enough to lack wifi connectivity. We're kind of locked into it with that proprietary system and can't switch thermostats without losing a lot of functionality and features.
I know some people love their Nests, but I find them to take more liberties with the auto-learned temp settings than I'd like (wide swing, etc.) If I were in the market for a standard stat, I'd probably pick up a new Honeywell T5 or similar, or an Ecobee. It seems that a basic-ish Honeywell or similar offers the best bang for the buck in terms of utility savings. I'd guess most folks don't save much with a smart stat vs a properly-programmed programmable (not one set to hold at 72, though).
Antiques, but they do the job fine if you set it, forget it and don't need a programmable one. Better than those "smart" ones your electric company offers for practrically nothing so they can overide it via internet during those high demand days in the summer time.Round ones are antiques.... Lol
So I have a basic older style digital thermostat.
My daughter has a new Ecobee.
My mom and step dad have a super fancy Goodman do everything one.
What kind do you have/like?
Huh? All the disconnects I’ve seen required a control box connected directly to the AC unit outside. Didn’t affect how the air handler inside operated one bit.Antiques, but they do the job fine if you set it, forget it and don't need a programmable one.

4 systems?.... Yikes!I like the round ones with the dials on them.
My house has four HVAC systems, two of the thermostats are fairly basic ones:

Whereas I had one system replaced last year and got a fancy new one which as best I can tell just has an annoying backlight:

I have a plain Jane tstat. Doesn’t even have a backlight. Yes, the disconnects out here were a unit that were installed on the outside a/c. I say were because they were an item for one season. People freaked when they couldn’t adjust their a/c on a hot day.Huh? All the disconnects I’ve seen required a control box connected directly to the AC unit outside.

If you don't need a new one you'll never have to worry about going to great lengths to get rid of the mercury thermo. It will outlast you.I still have the old one with an intact mercury switch. I figure I'll eventually go to a hazardous waste disposal facility to get rid of it.
I didn't need anything fancy. I just got a basic thermostat. It doesn't even have a thermometer function.
6500 square feet and a weird layout makes for an air conditioning disaster.4 systems?.... Yikes!
