Review of T9 Thermostat

So far, so good. I had a HVAC tech install it and it's working like a charm. It's easy to use and we know the house temperature from anywhere, which is great for when we travel. I would recommend this product over the Google Nest, which is more expensive.

Great Upgrade

Our local church HVAC was controlled with 6 Honeywell T7300 stats. They served there time but we needed to update the system so it could be controlled remotely and help with last minute schedule changes. The new T9s were installed with remote sensors and everything went smoothly. So far they are performing as expected.

Delayed install, older remote sensor tech.

I purchased the device a few years ago, but did not install it right away. After replacing our HVAC unit, we had to pull new wiring for the thermostat anyway, so installed this one. It has performed nicely. I wanted a remote sensor as well. I bought 2 newer ones that were incompatible before learning it needs the older technology.
