    • Works great with the app and supports remote sensors
Style: A. Wi-Fi Thermostat
If you have never used a thermostat with remote sensors, you really don’t know what you are missing. It is great being able to place sensors inside of rooms instead of having to hope that your hallway is the right temperature. That really only leaves two choices of thermostats, the Honeywell T9/T10 or Ecobee. We recently moved into a brand new house with two separate HVAC systems, one for the main level and basement, one for the top floor with the bedrooms. The builder pre-installed Honeywell T6 thermostats, which left a lot to be desired. They worked well with the Ring system that came with the house, but that control is limited to the mode and temperature. You either need to use the touchscreen on the thermostat or the app to make the most of it. Due to the way the T6 was installed in contractor mode, I could not get them to connect to the Resideo app. The T6 also does not support remote thermostats, which really is a game changer. There are a couple of differences with the T6 compared to T9. T6 has battery backup (I don’t really care as long as it doesn’t lose its programming). T6 connects to Z-Wave, which makes using it with a security system easier (plus Ring only supports two thermostats if they are connected to Z-Wave). Both connect to wifi and both should work with the Resideo app, but I could not get the T6 into the right mode to set it up. T9 has remote thermostats, T6 does not. I wanted more control so I decided to upgrade to the T9. The best part is that it was literally plug and play. I removed the T6 and plugged the T9 into the same wall adapter. I was able to immediately connect it to the Resideo app, which is really what I wanted. The Resideo app is actually not bad, it gives me full control over both thermostats. We have purchased additional remote sensors and have two for each thermostat, I really like being able to place them in bedrooms since we usually have our doors closed. I work from home and have one sensor in my office, one in our living room. I did find that occupancy detection doesn’t work as well as I had hoped because I use a space heater in hopes of saving money and that means the office is warmer than the rest of the house. In the summer and on weekends it works a lot better. With the Resideo app you can easily tweak the settings from anywhere and you can program each day individually. If days match it groups them, but they don’t have an easy way to remove customization for a day. That is nice because I try to go into the office one day a week. I wish I could program heating vs. cooling different for things like the fan because in the winter I want it set to circulate upstairs, in the summer I want the fan off on the top level during the day so I’m not moving the hot air around as much (those vents are in the ceiling), in the winter I want more air circulation. In my previous house we had installed an Ecobee 3, the first model with Apple HomeKit support (which we never used). The Honeywell T9 is competitive with the Ecobee in most of the features you will actually use, but that Ecobee had a couple of features the T9 does not. First, Ecobee supports accessories, for example, you could use it to control a whole house humidifier (I wanted one but never bought one). T9 doesn’t do that. Second, Ecobee can use occupancy to control whether your house is in home or away mode, which would be useful for our top level since nobody is in the bedrooms during the day. T9 uses geofencing, which has a lot of disadvantages in comparison (everybody needs it on your phone, cannot distinguish between home and on that level). Newer Ecobee models add even more sensors and even Alexa. Ecobee also lets you tweak how often the fan runs, Honeywell just has circulate, which runs on their schedule. Ecobee also looks more premium than Honeywell. The T9 is functional but not as modern of a design. Their sensors are large white blocks that really stand out when mounted on a wall. Considering all of the white Ring products I have, it kind of fits in, though. I probably would have chosen Ecobee over T9 if the price was similar, but Ecobee is nearly double the price and their remote sensors are more expensive as well. ... show more

    • WORTH IT, BUT CAN BE A HANDFUL TO INSTALL!!
Style: A. Wi-Fi Thermostat
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’ll need to find it inside the guts of your unit and run a cable from there to your new T9 (or if there’s an UNUSED CABLE from the usual 4-pack already running from your unit to your thermostat). This ‘common’ wire POWERS the thermostat in conjunction with ONE of the other 3 wires it uses - 4wires typically needed. I have a TRANE 4 Ton A/C Handler unit (2TEE3F37A100A) in Miami as we don’t use furnaces or boilers here - although our ‘air handlers’ (unit containing the cooling coils) do normally house a small electric heater that can easily handle the mild 5-10 short lived cold days we get to enjoy each year LOL. Anywho, my unit is about 12 years old and came with a Honeywell-made touch Screen thermostat TCON803AS32DA, which is NOT POWERED by the A/C Handler (Battery Powered) and thus, didn’t have this 4th C/Common wire in use. Figuring out which cable to use as the C/Common wire required 3-4 40-80 minute calls to RESIDEO (part of Honeywell) until I finally got a sufficiently knowledgeable REP to help me. I do have to say that they do try hard to help you and spend as long as needed to help you. It wasn’t until my last call I found the one that took me all the way to the ‘finish line’. So I had to open my A/C Handler and for each call log into a ‘Skype’ type of teleconferencing app (note: each technician used a completely different app to do it, so that was a bit strange, but I digress) so I could show them the ‘guts/inside’ of the machine and we could ‘figure out’ which cable going to the thermostat would be the ‘C’ - as my A/C UNIT’s WIRE TERMINAL BOARD didn’t show any terminals labeled ‘C’ - I’m guessing TRANE likes to keeps things mysterious so you have to call a technician who’ll charge $150 just for the visit (not here). So first 2 techs pointed me in WRONG direction. We used a VOLTMETER (if you don’t know what this tool is or how to use it, you fall into the ‘call a technician’ type of user and shouldn’t fiddle inside your A/C unit — unless it has a clearly marked C terminal). Anywho, you need a 24Volt terminal, but not just ANY 24V terminal (which first Tech picked one of 3 ‘W’ terminals because it had the required 24V, but still my Thermostat WOULDN’T TURN ON. So I was told I had a defective unit because I bought from Amazon, which isn’t an authorized distributor and probably mishandled unit by dropping it or being too hot in the WH. To which I responded, why? Because Home Depot (an authorized dist) wouldn’t drop it or keep it in a strict climate controlled environment? LOL. Anywho, I couldn’t wait another 2 days for Amazon to send me a new unit so I DID go to Home Depot and got one of their units - and guess what? It DIDNT TURN ON EITHER; so next Tech told me I had another defective unit after validating that the ‘C’ wire going to T9 did in fact provide 24V. At this point I hung up - I’m engineer and I know a thing or 2 about statistics, and chances of getting 2 BAD T9 UNITS from 2 completely different places are STATISTICALLY speaking, VERY SMALL. THIRD CALL was the charm. New guy told me all ‘W’ terminals are for HEATERS (I have 3), and the issue was that even though we were getting 24V at T9, it wasn’t COMPLETING THE CIRCUIT, so neither Thermostat nor A/C COMPRESSOR were going to work. At this point (20 minutes into back and forth) we took a 50% chance of hitting goal or BURNING something in my Air Handler by choosing as my C one of the cables going to the compressor since in theory, that would close the circuit; and BINGO it did indeed - T9 lit up. That wasn’t the end of the saga - then I had to call again - I lucked out with same guy - because the T9 had to be configured to know I had an A/C - it was only setup as a heater somehow. But a few clicks later, it was cooling. T9 Thermostat works as expected - and I REALLY LIKE IT and TOTALLY RECOMMEND IT - just like my old TCON803, it’s fully programmable and learns when to start cooling to reach your desired TEMP (although neither is extremely successful at it, but I suspect it’s my A/C which can’t handle the BRUTAL HEAT in South Florida in older homes lacking robust insulation). Also like my old 803, it RECIRCULATES THE AIR IN THE HOUSE 30% of the time even when the A/C COMPRESSOR IS OFF - this is KEY in keeping house cooler and not feeling like it’s too hot although thermostat shows DESIRED TEMP: we need airflow to feel temperature correctly. I like that back light is BLUE when cooling; ORANGE when heating, and WHITE when doing neither. THE BAD: the APP is what needs some work to be more useful - for instance, it could easily SHOW on BOTH ‘T9’ Thermostat and PHONE WHICH SENSOR(s) it’s using to ‘DRIVE’ / CALCULATE the INSIDE TEMP, yet that’s BURIED in one of the settings or the ‘PRIORITY’ menu, which is NOT INTUITIVE that you need to go here to find this - I have 3 additional sensors throughout the house and switch to master bedroom sensor at night to drive temp to sleep. To this end, both T9 and APP will show the ROOM NAME where Thermostat is located under the current inside temperature, making it completely misleading - in my case both T9 and APP displays will say FAMILY ROOM 71F, but it’s REALLY 69F in the family room; the 71F degrees are coming from a SENSOR IN MY MASTER bedroom, which runs hotter, and thus why I switch to it at night to drive temp. APP is VERY BUGGY TOO - it will often show BOTH WRONG INSIDE TEMP & WRONG TEMP SETTING, which requires killing app and starting it again. I have the latest iPhone 12 Pro Max and iOS version (14.7) as of this writeup, and super fast Wifi, so neither of those are the issue (oh!, and I’m referring to this happening while I’m home - I have no way of validating if the readings are outdated once I’m not home - I can validate them at home because the app values don’t match the ones on thermostat). Anywho, that was a novel, my apologies, but you got the whole story. Best of luck with your instal. Despite all the hassle, it was TOTALLY WORTH IT! ... show more

    • Great instructions!!!
Style: A. Wi-Fi Thermostat
Review Image by Crystal L Lightfoot Crystal L Lightfoot
A lot of products nowadays are brought into our lives with "easy setup" or "quick install", then you get to the instructions, and get confused about 3 steps in. The Honeywell T9 Thermostat instructions are NOT like those others! I ordered the product, fretted over installation and difficulties, and waited one day. This morning I opened the box, got out the instructions, and started at step 1. It went flawlessly!!! Even has tips for people like me that don't have experience dealing with electrical wiring! I would definitely recommend for anyone wondering if they can do this without a professional. If you have a drill, screwdrivers, pencil, and level, it's no problem! I applaud whoever wrote the instructions for it, and it works great! ... show more
