5.0 out of 5 stars Great thermostat, June 18, 2007

We moved into our new home 1-1/2 years ago and it came with a builder's grade Honeywell thermostat. There is also a fresh air duct leading into the return air grille area. I wanted to cycle the air about 30% of the time but couldn't do it automatically with the original thermostat.

I ordered this Honeywell TH8321 thermostat and had planned on having an electrican install it. When he was out installing ceiling fans in our house, I asked him to install my new thermostat. He wouldn't touch it, mumbling something about that it would require someone to get into the air handler/furnace and change the wiring.

Well, the next day I looked at the installation instructions and discovered it only required 4 wires to hook up, the same as the old one. So, I took the old one off (after turning off the power) and installed the new one. It took no more than a half hour total. The setup instructions were straight forward and very clear to understand. I turned the power back on and WALA (sp?) and it worked and has ever since.

I like everything about this thermostat. The air cycling, humidity indication, current temp setting and current temp, time, day, etc. It's everything I wanted and more. I did buy the outside temp sensor but haven't hooked it up yet. (The electrician wouldn't touch that either)

This is a do-it-yourself project even though the instructions warn you to have it done by a professional.

5.0 out of 5 stars Solid thermostat with great features, November 3, 2009

In contrast to others, I have found this to be an excellent thermostat. It was easy to install myself and has a lot of great features. It automatically adjusts for high humidity by using the air conditioning system. It drops the set temperature lower to bring the humidity more in line with the level set by the user.

The Intelligent Recovery system is also great. It learns how long it takes to heat/cool your house and, instead of simply turning on at the programmed time, reaches the desired temperature at the desired time.

The only downfall is the short backlight cycle, which isn't a problem if you hardwire the unit since it can be set to keep a reduced backlght level all the time. But if you rely on batteries, as I did, the light turns off until the screen is touched and only stays lit for 8 seconds.

That's certainly no reason to pass on this thermostat, which I bought off the popular online auction site (you know which one) for $80, including shipping.

4.0 out of 5 stars Excellent thermostat, but get used to hearing it "click", January 19, 2010

I bought this unit as a replacement for my Chronotherm 7-day programmable thermostat, which worked well until one of the pins connecting it to the baseplate gradually shorted out and did not allow the fan circuit to come on anymore. I was glad to see that Honeywell has greatly beefed up the pins connecting the TH8321 to the baseplate, making them much thicker, making for a more solid (and hopefully long-lasting) connection.

This thermostat is a great product overall - I especially like the "circulation" feature, which runs the fan randomly, to help keep a more even temperature in my 1-zone house. My only complaint is that the relays are very loud, and make a noticeable <CLICK> whenever the fan, A/C, or aux heat turn on or off. Seems like a major oversight in an otherwise very well-designed product.

Also I was disappointed to learn that I needed to buy a different external temp sensor than my previous Honeywell thermostat (the resistance must be different), but once purchased it is a nice feature to be able to see the external temperature continuously on the backlit screen.
