 Do not buy this thermostat July 21, 2010

Bought this at Home Depot, installed, worked great. 2 months later, we can't get the AC to blow. Called heating and cooling tech who told us that we would probably need to replace our blower or control panel. We were looking at major $$$. He comes out and after a couple of hours determines that the thermostat was faulty, installs our old one, and AC works again. He told us to try to recover the $100 service call from Honeywell. Yeah, right. After wasting 25 minutes on the phone, Honeywell tells me they will get back to me. I thought Honeywell was quality, won't make that mistake again.

My husband and I purchased 2 for cost saving purposes:
1. The directions read that it takes 15 minutes to install - it took us 5 hours and after installation, it didn't work properly so we had to contact an electrician who charged us $200.00. The electrician warned us as he installed both stating that he commonly has to assist customers who have purchased this same item from either Home Depot or Amazon. He said they typically have been faulty and they don't even make them anymore - NICE!
2. The thermostats are not accurate as far as the tempurature settings. We set ours on 72 and work up during the night sweating in which our separate home thermostate read 80. They are off completely.
3. The program doesn't run as programmed - on occasion, you manually have to run it.
After spending 8 hours dealing with these and $300.00 later - we are completetly frustrated and plan on returning both. Amazon should not sell faulty items that are obselete.

This is my second 221b thermostat for half the price I paid my plumber to install my first one. I installed this one myself in my media room for a gas stove no problem. Works great.
