## Description

Thermostat

Review: Muy fácil de usar y la aplicación facilita a se pueda encender o apagar si saliste de casa
Review: Update 14 May 2024 Both Units are still Working Perfectly after 3 Years! I am so happy with this purchase that I just bought a third one as a spare! The model might change and I at least know that this one works perfectly and still looks very modern. So now I will have a Spare in case one should die. The only issue I have ever seen is that occasionally it sends me an email that the one of the Thermostats does not have it's time set correctly. I open the App and every time the time is correct, so I just delete the Log entry and the Alert Notification is gone. I think that the Thermostat tries to get the time and maybe once every two months it just cannot reach their servers. ORIGINAL 2021 REVIEW: Great looking unit with a lot of control. The programming is a bit confusing at first because there are just so many features that it can be a bit overwhelming. The effort involved in learning it is well worth it as you will wonder how you ever lived without these features. If your into energy savings this unit is a must have thermostat as you can schedule the temperature so that it is comfortable when needed but not cooling or heating as much when your not home. Holiday scheduling etc are built in features as well as a very nice AI system that gets the temperature to where you want it at the time you want it. For instance I set the office Temp to be 73 Deg at 9AM. These thermostats calculate based on learning the temperature curve for your systems. It knows exactly when to turn on the AC so that at 9AM it is 73 Deg. In my case it learned within a day and adjust depending on the temperature in the morning. Right now the AC units come on at 7:45AM and it cools down so that when we open the office door it is perfect 73 deg inside. Heating works the same way. When closing time comes it shuts off the AC compressor but runs the AC Fan for an hour or two to dry out any moisture in the coils and ducts, this is a great feature as it eliminates the chance of mildew growing in the system. All of this is configurable in the Menus. Remote access has been great for me so far. I have not had any issues with their servers being down. I can pull up the APP on my phone and change certain things or I can do it from a PC using a web browser. I was a little disappointment that not all parameters can be changed remotely. You can change the temperature settings also change the scheduling and do manual shutdowns or turn On but the rest must be done from the head unit. I installed two of these in our offices. One controls a 10 Ton Carrier AC unit and the other a 7 Ton AC Unit. The installation was easy. The "C" terminal and "RC" terminal hookup to the 24VAC transformer and the "C" and "Y" terminal hook up to the 24VAC compressor contactor. The "G" terminal is for the Fan relay board on the AC. Pretty much a one on one wiring from any older manual thermostat it may be replacing. Overall I am super impressed with this thermostat. It keeps the time using internet servers and does not loose any settings after a power outage. If the WiFi is down for any reason it keeps on working based on the schedule and their remote servers email you to let you know the connection has been lost. It has several email alerts including the temperature going out of set parameters which might happen if someone left a window open or you HVAC system broke down. Once setup it's pretty much a mini AI system that is keeping your house or office at the temperatures that you want and alerting you if something is wrong.

## Questions & Answers

**Q: What is the difference between this thermostat and the rth9580wf1005?**
A: There is no functional difference between the two.  This TH9320WF5003 is white and the RTH9580WF1005 is silver.  The  RTH9580WF1005 is the retail model with a 1 year warranty and this one is intended to be a contractor only model with a 5 year warranty.  Honeywell's former policy was that the TH9320WF5003 warranty wouldn't be honored if not installed by a contractor.  However, they have since changed this.  You now get 1 year with this too if you install it yourself.

**Q: What do you mean bty requiring "C" wire?**
A: In an HVAC system there is a step-down transformer that takes the 240VAC or 120VAC and steps it down to 24VAC. The primary side of the 24VAC is what has always been connected the R terminal of a thermostat. The secondary side of the 24VAC transformer was not. It is this secondary side of the 24VAC that is needed by newer thermostats. In fact the newer thermostats are powered by 24VAC. That secondary side of the transformer is what is connected to the C terminal. If your cable has a spare unconnected wire. It could be connected to the secondary of the transformer and you can check for it  To see if it is there but but not connected, us a VOM and set for AC Voltage, put one lead on the R terminal, and the second lead to each unconnected wire(s), one at a time. if it shows 24VAC +/- 4VAC, you found the secondary side. All other wires will show OC or open. That secondary side wire is the C wire. If not found, an HVAC technician can come and make the connection of the spare unused wire at the HVAC unit side.  There is deadly voltage and currents in the HVAC system so do not try this yourself.

**Q: If power goes out and wi-fi is lost, can it be reconnected remotely or automatically?**
A: Most often this will reconnect. On the occasion it does not, restart your modem. You may have to reconnect to Wi-Fi again but this is rare.

**Q: will it still function if not connected to the internet?**
A: It must have a connection to their website, and if either your internet goes down or their website is not available, you can only control it from the thermostat itself. 

Their website goes down several times a week, so no control, which sucks; I would not recommend this thermostat if you need the remote control.

### ⭐⭐⭐⭐⭐ Review
*by A***R on 7 January 2026*

I replaced my standard Lennox Thermostat for the Honeywell 9000 Wifi Smart Thermostat. I use this product with my Lennox 2 stage Furnace. My original thermostat did have the "C" Wire which the 9000 requires. Installation and instructions were straight forward, just make sure you document all the wires on your existing thermostat. The 9000 can be used in PROGRAMMABLE and NON- PROGRAMMABLE (simple) mode and can be controlled remotely from a Desktop or IPhone App. I love the colorful display as it is very appealing. I am very satisfied with this product and pleased with my selection. I would buy this product again.
