Rated 3.9 out of 5 by 19 reviewers.
Rated 5.0 out of 5.0 by Very nice, no frills 7-day programmable Thermostat I bought this to replace an old mercury thermostat. The installation was very easy and straightforward, no C-wire required, runs on batteries. Each day has multiple modes, so mine is setup to warm the house as I wake up in the morning, let it be cool during the day, and warm up in the evening before shutting off at bedtime. I've had no issues with the thermostat and it is very well-built. If you are looking for a quality, programmable, no frills thermostat then this is the one for you. December 10, 2014
Rated 5.0 out of 5.0 by Set and Forget I actually purchased this unit on accident, grabbed wrong product. By the time I noticed didn't feel like going back so installed it. Installation was fast. Setting up took a little while, but in the long term will pay for itself compared to old mechenical one that I always forgot to turn down. It has a clock, actual temp, set temp on face and lights up when in use. It also has a hold button that overrides set temp which is nice. Glad I grabbed wrong one. January 9, 2013
Rated 1.0 out of 5.0 by 3 1/2 Year Thermostat Purchased this stat 12/14/11. Replaced batts once a year. 01/01/15 new batts installed since the screen was blank. 03/31/15 replaced batts since screen was blank again. Today, 04/09/15 partial screen readable so replaced batts again - NOW just a blank screen (tried 3 different sets of batts). Duracell batts are the replacement brand. 3 1/2 years for $50.00 means I am not happy with Honeywell RTH2510. April 9, 2015
Rated 4.0 out of 5.0 by Ecellent Bought this on sale, it was a great investment. Thank you July 21, 2015
Rated 5.0 out of 5.0 by Honeywell 7-day Thermostat is Perfect I should have bought this 7 years ago when I bought my home. Super easy to install and program. Do not hesitate to buy this 'stat, it's an excellent value. My electric bill is lower already and I suspect it will shine in the winter when my furnace really sucks the juice. Purchased for a central air system not a heat pump but will work on either. July 16, 2013
Rated 2.0 out of 5.0 by Not a 7-day thermostat The packaging says this is a 7-day thermostat, but it is not. it is a 5+1+1. That means you can control M-F as a group, but not individually. June 23, 2013
Rated 2.0 out of 5.0 by mediocre at best The instructions were not clear and when I contacted the HELP line, the lady was of no help. She obviously had no technical expertise. The time set function moves too slowly, the up and down temp buttons move too quickly. The cover is very difficult to remove. I expected better from Honeywell. February 11, 2015
Rated 4.0 out of 5.0 by Good for the price Decent programmable thermostat for the price. Not as easy to program as the touch screen we had before but not too bad considering how much less it cost. Was easy to install!! Biggest issue I have is that it is not the same size as the one I had before and will now need to repaint the wall. :( June 3, 2014
