Honeywell Home T9 RCHT9510WF

Overall, the T9 is a good smart thermostat system, with an easy-to-use interface and a decent amount of flexibility in how you can control it.

Thermostat does work how it should but does not have adjustable temp swing. Currently our a/c cycles every 10 min because it changes by a degree. Wish it had a 3-4 degree adjustable swing.

WARNING: it’s a DISSERTATION, but worth reading if you face a missing C/COMMON wire. T9 itself is Easy to install AS LONG AS YOU HAVE A ‘COMMON’ WIRE in YOUR EXISTING THERMOSTAT- in that case your install is probably 15 minutes. Else it can be HELL figuring out which one is your ‘common’ wire as you...

Because I have owned both Nest and Ecobee thermostats previously, this review specifically compares the Honeywell T9 to those products. Here is where the Honeywell T9 is superior to the Nest or Ecobee - Price/Value: The T9 is priced very well compared to the other options and offers most of the same...

With some research and improvising, I managed to install two of these, one with old 2 wire 24v wiring to hydraunic heat, and one with 220v electric floor heating. The instructions only describe newer systems with fully labeled wiring, so I did some research to decode what each terminal was for. The ...

I like this overall. It's a clean look, easy to tell if it's heating (red background), cooling (blue background), or off (white background). Set temp is in big letters that are easy to see from across the room. The outside temp is nice to have in small font below, but I seldom use that. Easy to prog...

The physical installation was easy since I’ve installed a thermostat before. The old thermostat is shown in pic. BTW, the blue unused wire is the C-wire. Anyway, my only gripe is the Honeywell Home app didn’t work for me. And after wasting an hour, I discovered online that the Resideo app was a repl...

Tried and tried to get geofencing to work for my wife and I. Could not get it to work properly. It worked sometimes but would then say we were away when we were both home. Very frustrating and gave up on the geofencing. Switched to schedule format to be a simpler setup. Then tried geofencing again. ...

Our home came with a "dumb" T6 thermostat. But being a newer Honeywell thermostat model, the backplate is the exact same as the one that came with this thermostat. So installation was literally pull the old face panel off, and snap this one on there, plug and play, 30 seconds job. Setup was incredib...

I wanted a thermostat that I could program, not on that was self programming to my schedule (large internet company one). This is it! Works great. I have a heatpump system, and had no problems hooking it up. It has a weekly schedule if you want to set five days easily, or you can do all seven separa...
