PRODUCT OVERVIEW

Model # RTH8500D

Internet # 100295793

Some programmable thermostats are so difficult to program that people just put them on hold, defeating their purpose. Honeywell's Universal Touchscreen Thermostat is so easy to program, most people don't even use the manual. This easy-to-read, easy-to-use Universal thermostat works with virtually all system applications. Plus, you can save on heating/cooling costs if used as directed.

  • Extra large touchscreen display shows room temperature, set temperature, and current temperature all at once
  • Universal application - works with conventional and heat pump systems up to 2H/2C; it's one thermostat for nearly every application
  • Effortless menu-driven programming guides the user through the programming process, only showing necessary information and choices - eliminates unnecessary clutter
  • Separate programming for each day of the week - 4 periods per day
  • Battery free operation - option to power with heating/cooling system so you never have to change batteries again
  • Vacation hold - option to adjust your program and have it automatically resume to the normal settings in time for your return
  • Daylight saving time - adjusts the time automatically

CUSTOMER REVIEWS

Rated 4.3 out of 5 by 43 reviewers.
Rated 5.0 out of 5.0 by working great We purchased this on recommendation of our heating/ac repairman, who said we could easily install it ourselves and save money. We assured him we are barely capable of do it yourself projects, but he reassured us. The package said it would install in 15 min.Only 3 hours later, we had ours running. There was a very tiny u-shaped piece of wire that had to be in contact with a particular place on the thermostat. It was on the right side, thus having to be inserted from the left. For right handed people, this was nearly impossible due to the size and precision required. After countless tries (and numerous drops to the carpet of this teeny little piece of wire), we finally did it! Everything after that was simple, and the thermostat is doing what it is supposed to. There are many good features on this that we have not used yet, but it seems to be a pretty good value (installation aside!). December 9, 2014
Rated 5.0 out of 5.0 by Very easy to program I bought this thermostat to replace an old non programmable unit. I've had it for about a month now and is very easy to program. I installed it in about ten minutes with no trouble whatsoever. Thanks for reading my review! May 15, 2013
Rated 1.0 out of 5.0 by Will NOT work with 2-wire heating systems For those homeowners with a simple 2-wire home heating system you might have issues getting this to work properly. FYI, I have a gas fired steam boiler with just a simple 2-wire hookup to a 8-year old failing Lux PSP511 thermostat....bad button requiring multiple presses, added pressure, and various angles of pressing to allow me to vary temps up or down. Other than this the Lux thermostat was rock solid in performance. Spec'd out both Honeywell and Lux and mistakenly put my faith in Honeywell's touchscreen unit with a large display since eyesight was getting worse as I aged. Simple 2-wire hookup (red wire to Rh and white white to "W" ....nothing really complicated. Struggled with this and calls to Honeywell yielded pushback to hiring a heating/ac contractor because quote ....."...our thermostats are very exotic and extremely complicated in design". Return trip to Home Depot this time purchased a more current Lux with touch screen, large numbering and backlight. Same hookup with the same wiring gave me a heated home in less than 10 minutes. Think twice and lean towards a Lux ...same or more features at half the cost. Still not happy with Honeywell support...simple 2-wire hookup...we are NOT talking about finding a cure for world hunger or sending a man to the moon Honeywell November 8, 2014
Rated 4.0 out of 5.0 by Easy to program This thermostat was very easy to install and program and it has the feature I wanted the most - 7 days of 4 periods (wake, leave, return and sleep) heating. Many thermostats only have 5 days of 4 periods and only 2 periods on the weekends, however, I work weekends, so my old thermostat was impractical for me. However, I am a light sleeper and the thermostat has a "learn" feature in which it comes on in order to reach the desired temperature before I wake up in the morning. So if I want it to come on at 7, it actually comes on at 6. I still have to figure out how to have it come on when I wake up as opposed to earlier. Otherwise, it works very well and it is really easy to program. October 15, 2013
Rated 5.0 out of 5.0 by The thermostat was easy to install and it is very simple to operate. The thermostat is a 7 day programmable thermostat that allows 4 different time periods each day to be controlled. It is completely touch screen operated and has been easy to use. May 21, 2013
