HoneywellTH6320ZW2003 T6 Pro Series Z-Wave Stat Thermostat &, Smart Home

The wiring instructions are well documented and simple to follow. By good luck the mounting screws matched the Sensi mounting plate I was replacing. As a result, I mounted the thermostat in about 5 minutes. There are an intimidating number of selections for configuration but the defaults were correct for my heating-only configuration. Multi-stage heating/cooling with inside and outside sensors may take a bit more time but it seems like there are plenty of control options for such systems. Z-Wave connection was trouble free and it works nicely with my hubitat system.

It was very easy to install and provides a good amount of data onscreen.

I chose the T6 Pro Z-Wave thermostat for my multi-zone hydronic heating system in my house. Basically, I needed a thermostat that didn't require a C wire, would have long battery life, and still be "connected" for the whole "smart home" experience. I chose Z-Wave over Wifi connected and use a Samsung smartthings hub.Installation was a snap and in the months I've had the thermostats they have lived up to my needs. I haven't had to change batteries yet in any of the 7 units and the connection has been straightforward.My one gripe is that the Alexa integration doesn't work well. I can ask for the temperature in any room and that works well. But turning the heat on and off has required me to set up a custom "routine" and then I have to go look to see that it worked. Forget about setting the temperature. I can't tell if it's the manufacturer's integration or if it's on the Amazon side, but so far... no luck.Still, I'm happy with my purchase and think these are a good choice in general, even if not perfect.

I installed this on a heat pump and had it working fine, providing AC. This is a second house, so I left and check it several hours later and it was 6+ degrees hotter. So I turned it off remotely. When I checked the temp the next morning it read 99 degrees! I had to send a neighbor over and they told me the heat was on (even though the thermostat read "off." So I figured I messed up the install and called the HVAC company that put in the HP. They spend about 4 hours setting it up. Unfortunately, about the same thing happened. Worked for while, then turned on heat even when turned off. It caused my downstairs to reach about 96 and the upstairs well over 100. This caused my frig to malfunction and thaw everything while I was gone. Fun cleaning job. I don't usually leave feedback, but wanted to warn others. I called tech support and it seems this has happened before.

Absolutely easy to install and looks nice - very modern looking and sleek. I'd advise examining the manual prior to installing and be sure to understand each setting prior to popping it on the wall. Make sure you know what type of HVAC equipment you own and its capabilities such as system type, number of heating and cooling stages, etc. It will make setup much easier and possibly save your equipment from damage due to to improper settings. The nice thing is, you can pop the batteries in and run through the settings before attaching it to the mount. (If your current thermostat has an advanced or installer setup, I'd also recommend running through it and figure out how it is currently configured). Any of these settings can be adjusted after installed, including z-wave inclusion. I have (both) mine attached to my HomeSeer system. It included without a hitch and the configurable devices created exceeded my expectations. Adjustments are a breeze from the app or web interface and reporting is instantaneous. Here is the best part... there is no cloud service involved! I had Honeywell 7 Day WiFi thermostats, and was pleased with them, but had intermittent disruptions of service because their web API is constantly offline. That isn't a problem anymore. I couldn't be more pleased with this thermostat. I highly recommend it.

Great product. This was easy to install and sync to my Z-Wave network. Fully controllable through my Habitat. Very accurate and efficient temperature control as well!

I was looking for a ZWave thermostat that did not require a C wire. This device easily connected to my SmartThings hub with full control in the SmartThings app and voice controls in my Google Home Hub. Batteries, in case of no C wire, work for months due to the simple LCD display.One thing to note, if you are running off of battery power the device will not act as a repeater for your ZWave network. A C wire is needed if you want to use this to expand the size of your network.

Fast shipping and the device working as expected.
