HoneywellHome RTH2300B1038 5-2 Day Programmable Thermostat, White

This is an excellent deal for a super affordable price. The set up couldn't be safer/easier -- and it worked well with my extremely finicky and outdated system. Really easy to adjust the thermostat and set timers (up to 4) during the day. 10/10 would recommend if you don't need anything fancy!

Add 2 AAA batteries and snap into place. The first one of these I bought was about 5 years ago so I already had the base mounted and wired. So, this install took about 3 minutes...

It was reasonably easy to remove the old thermostat, and then install this one. My only issue was that the images make it look bigger than it is. Not that big of a deal of course. I got a little painting to do.

I had a slight problem with turning this on but it was the summer months. Customer service helped and works properly. Good product for the price.

I installed it myself! My first at 71.

Works well, easy to use.

This review is for the Honeywell RTH2300B1038 5-2 Day programmable thermostat. It works OK (meaning that it turns my furnace on and off), but it has several drawback that don’t match its higher price point over less expensive thermostats that have greater functionality.Installation was not quite as straight forward as I expected, I had to cross reference some youtube videos to make sure I was correctly leaving the blue thermostat control wire disconnected. A few extra details in the instructions would be helpful here. The first thing I noticed when it was connected and powered up is that it had the same dark/dirty area in the lower right corner of the green backlight that everyone else has pointed out. Definitely some quality control issues during manufacturing here. There’s a confidence booster… This isn’t really a big deal, because I don’t need to use the backlight.The next think I noticed was the deal breaker for me: though there is a five-day and a two-day program, there is only a single group of settings that will apply to BOTH the heating and cooling cycles. During the winter, we keep our furnace set a bit lower, usually around 67 degrees. During the summer, we keep the air conditioning set higher, around 75 degrees. You cannot achieve these setting with this thermostat - you only get one set of settings. This means you have to reprogram the thermostat every time the season changes. Call me lazy, but this introduces hassle that wasn’t present with my previous thermostat. This means I would need to write down the settings in some place that I’ll be able to find six months later. No thanks.The next thing that I noticed is that this Honeywell thermostat causes my furnace to cycle much more frequently than the old thermostat did. This results in more wear and tear on your furnace and air conditioning compressors. There might be a place to adjust this behavior, broadening the temp spread for the turn-on and turn-off points, but given that it only has a single set of time/temp settings, I had already made up my mind to return it, so I didn’t bother looking through the manual to see if this is possible or not.If you find yourself in need of a new thermostat, save a few dollars and pick up a Lux Pro PSP511C thermostat that is much better. It has separate time/temp setting for heating and for cooling and you can easily adjust the on/off temp spread so your equipment cycles less often. This saves wear and tear and is also more energy efficient.

Works as it should.
