Excellent Product!!!

Comments about Honeywell Wi-Fi Smart Thermostat (RTH9580WF):

Important! Make sure you have the C wire before purchasing this product.

Product functions like a dream! phone access, security lockout, step-by-step setup, wifi connection all work easily & flawlessly! Wish I would have invested in this years ago. Accommodates Heat Pumps, forced air, & gas/electric furnaces & A/C. Auto mode controls Furnace and A/C simultaneously so once you set your desired temp min&max, you don't have to worry about it year round. Very much worth the $$.

Only one slight irritation is the mounting bracket on mine isn't as secure as I'd like it. It works, but doesn't snap securely into place.
