Works great. Based on a previous review, I replaced an existing T4Pro that the renovator had installed with a T6Pro. I wanted the convenience of WiFi access and scheduling but wanted to retain the compatibility with my HVAC system. The T6PRo was perfect and no additional wiring was required. Simply unplugged the old unit and plugged in the new one! Now, via internet I have access from anywhere. And scheduling is much easier than the old T4Pro.
Nice looking connected stat. Easy to configure wifi. Wish it was coupled with a Honeywell app. Still have to figure out how to reduce the minimum set point.
