Great Product and Very Easy to Install

This is the first time I installed a thermostat, and just by following the instructions on the manual I was able to complete the task in under 20 minutes. It does everything it says and now I can control the AC unit from anywhere with my smart phone. I am an extremely satisfied customer.
