 Honeywell 7500 August 16, 2008

This unit has performed admirably in AC mode, and I am sure it will continue to do so in winter. Installation was easy and instructions were clearly written. Because of its tighter temp control range, my AC has run more efficiently.
It is a well designed product worthy of consideration for any thermostat replacement or upgrade.
Wiring can be tricky July 20, 2008

This review is from the perspective of a novice. I replaced an 11-year-old thermostat with this one yesterday morning.
Installation was not a breeze as the claim on the product package would like you to believe (i.e., "designed to install in 15 minutes or less.") We have a 5-ton split central unit with the condenser outside of the house, and the coil and a gas furnace in the attic. Matching the wires to the new thermostat was not that straightforward. Our old system has 5 wires but the Intallation Guide only shows an example with 4 wires. After failing a few configurations, I finally gave up and called for technical support. The puzzle was then resolved.
Programming was mostly simple and easy but not always intuitive. You do need to read the Manual to figure a number of things out. An alternative may be the 8500 Touchscreen model, which seems to have more intuitive programming based on reviews from Amazon users.
Overall, I would recommend this thermostat. Just make sure that you do your installation during office hours when technical support is available from Honeywell.

I got this thermostat to replace an older Honeywell model that was OK, not anything special. The feature that sold me this t-stat was Auto Changeover where the stat decides wheter to turn on heating or cooling. I live in the desert where wild temp swings are a fact of life and thought this stat would automate things a bit for me. No such luck. The documentation says that you may not see the auto changeover feature on the readout depending on how the stat was installed, no instructions on what to do about it, just a statement.
OK, it's installed and seems to work. Programming is way too complicated. The book is full of process numbers and other gobbledy-gook that makes no sense. You can program seven days separately if so desired. I opted for one program for Monday thru Friday and a different one for the weekend. I'm at work now and have no idea what the thing is dong on the five-day program.
If I had it to do over again, I'd probably get a different unit, or just keep the old one and manually change from heat to cool and back again.
A non technical homeowner's experience in installing and using this thermostat. May 30, 2008

I purchased two of these thermostats through the Amazon website and installed them just before the start of the Memorial Day weekend. I am very pleased with both thermostats, but I did encounter a problem during the install of the upstairs thermostat. Although I had flipped the breakers labeled for the upstairs and downstairs heat pumps to the off position at the panel, the upstairs heat pump was still receiving power, because I blew a fuse in the heat pump during the install. Obviously this problem was caused by a lack of due diligence on my part - ensuring that the power to the heat pump and to the thermostat was really off. My wife and I went without air conditioning to the upstairs of our home for approximately 30 hours before a service technician arrived to find and replace the blown fuse.
If you have a volt ohm meter, I suggest that you verify that there is no power to the thermostat prior to the install. In doing the install yourself, you may find that you are at the mercy of the wiring provided for your old thermostat. For example, on our old downstairs thermostat, there was no common wire. When the heat pump (air conditioner) is on, the lead for the furnace is used as the common. When the furnace is on, then the wire for the air-conditioning is used as the common. Without a common lead as a reference, it was not possible to measure the voltage to our downstairs thermostat when neither the air conditioner nor the furnace is running. This led us to believe that we had no power to the thermostat even after we had switched the breaker back to the on position after the install. However, the thermostat worked fine. The service technician explained to us that in the original wiring to our old thermostat, the common was missing and that was why we could not measure the voltage.
I called the Honeywell support number on the back of the thermostat installation manual, and a technician located in New Deli answered immediately. The technician was friendly and knowledgeable.
Two messages that may appear on the thermostat after you install it may lead you to think you have made a mistake when nothing is wrong. First, if you have a heat pump and the word "Wait" appears on the thermostat display after turning the heat pump back on, then this is normal. As a precaution the thermostat waits five minutes before cycling the heat pump back up after it has been turned off. Second, if the word "Recovery" appears on the display when you first turn the furnace or air conditioner on, this simply means that you have the Smart Response Technology set to on, and your thermostat has turned on you air conditioner or furnace to reach the target temperature that you set in the schedule.
With my old mercury-based thermostats, I could not be certain that the correct temperature was displayed. Nor could I be certain of the actual temperature that I was setting the thermostat to. If I left the thermostat set to a high setting while we were away on summer days, then the house would not cool off before bed time after we got home. All of these problems are solved by our two programmable Honeywell thermostats, and I saved over $40.00 by buying the thermostats through Amazon rather than Home Depot.

This is the third thermostat I bought. First got a White Rogers which was cheaply built. Then got a Lux which read the temperature inaccurately and didn't work. Both were difficult to wire and the manuals were bad.
Finally bought this one. The internal mechanism makes it a breeze to wire. I agree it is confusing to program, particularly compared to my last Honeywell (it gave up the ghost). Once you have it set up however, it is great. WORKS!
Man, we need to move manufacturing back into this country!!!! Tired of wasting time and money on cheap imported junk!
