Controls extremely well
Replaced a round Honeywell mercury thermostat with this to control steam heat in a turn-of-the-last-century residence.
Installation is very straightforward, and the modular wiring panel means it can be updated with a programmable or communicating model without tools.
Temperature logger showed the round t-stat swung 5°F, this one controls to better than 1°F.
Do everyone a favor and use lithium AA cells, they don't leak.

This product is just what I needed.
SET & FORGET. The T3 Pro Thermostadt (Non-Programmable) is very simple and easy to use. It was also easy to install. I had no C wire connection, so I used the battery option. It replaced a 35 year old unit that still worked. If you do not need all that wifi stuff, this is a good product, and a good price, too. The sales person I talked to was informative and pleasant. The order process was easy and it came quick. IT WORKS!
