CUSTOMER REVIEWS

Rated 4.1 out of 5 by 34 reviewers.
Rated 5.0 out of 5.0 by Just what the Doctor ordered... The unit is simple in design and function, has easy to understand instructions on setting it up, and works flawlessly with a mechanical simplicity that borders on genius. My older thermostat, a fancy computerized model that allowed for network connectivity and web-based controls, lost it's mind - literally. Suddenly my house was getting hot - fast, yet the 'stat said all was well. Go online and it said differently and it refused to let me change it. After many hours of Frankenstein's monster tormenting us, I gave in and went low-tech. My only CON on this unit is it's small size when compared to the larger more elaborate thermostats: wiring with older, thicker wiring like my house means you have to take extra care not to cross anything when installing it. Other than that, I love the simple use and ease of install. I'm never going back to the high-tech stuff like that again. August 28, 2013
Rated 1.0 out of 5.0 by Lousy air temp calibration Bought this to replace old 'gold/round' Honeywell thermostat that was installed in 1958. This new version is solid state and one would think have better accuracy for real air temperature in the house. But no. Compared against an old but reliable analog thermometer of known good status and a laser thermometer with high accuracy, this new product registers 2-3 degrees lower than the true air temp...consequently, the oil fired furnace cycles on/off throughout the day. On the Internet other consumers have identified the same problem, some folks even trying 2-3 of these thermostats only to discover this is a systemic issue. Save your money. This is a very poor product. February 13, 2015
Rated 1.0 out of 5.0 by Solid State: Does not replace older models This does not replace older mercury or mechanical units. Honeywell has changed to a solid state design which requires 24 VAC to run. The unit would probably work okay, but I down-rated it to one star, with a non-recommendation, because the 24 VAC power requirement is not mentioned anywhere on the packaging. You don't discover that fact until you read the instructions. If you need to replace an older mercury or mechanical thermostat, you likely will not have 24 VAC wiring to the thermostat location. Instead, look at the model CT31 or one of the battery powered digital models. February 16, 2015
Rated 4.0 out of 5.0 by This product simplifies your heating and cooling operation. It removes the "guesswork" of setting set-back thermostats. Easy to install. I am not gifted to set these new sat-back thermostats, sometimes the heat comes on in the middle of the night because I didn't correctly input the correct information. it's easy, before you go to bed, turn down the heat, when you get up in the morning, turn it up to your setting.

Rated 5.0 out of 5.0 by Up-Dated Thermostat Removal and replacement of the old to the new thermostat was very simple. It only required the removal of 5 wires and since they were color coded screws, and their placement on the new thermostat was clearly marked as to what color went where, it was a simple no brainer in installation. February 10, 2015
Rated 2.0 out of 5.0 by Don't expect ant help from Honeywell Customer Support Followed instructions for removal of the original Honeywell T87A thermostat and ended up with six wires, two of which didn't appear in the replacement instructions. Ended up calling Honeywell 3 times only to get told that I needed to call a repairman because they didn't have any information on the Honeywell T87A thermostat and Honeywell W226A Evaporator Sequening Control. At their request, I traced all the wires and found that they were wired exactly as shown on the W226A Box cover schematic but they refused to accept the terminal pinout labels telling me they don't use what they printed on the box cover. If your new thermostat isn't a wire for wire replacement, you won't get any help from Honeywell even if they originally made the product. November 13, 2012
Rated 5.0 out of 5.0 by Can't improve on such a classic Worlds most popular thermostat. What else is there to say. Does exactly what it is supposed to. No more and certainly no less. September 27, 2011
Rated 5.0 out of 5.0 by Basic, good buy. Basic unit, very easy to wire, no batteries to change. Overall a very good unit as long as you don't want to program one. January 20, 2015
