Asked by: Ken
How to program this thermostat
Answered by: Tamara
Date published: 2019-01-25

I used to have a Honeywell which had an auto mode, that change from heat to cool with a temperture range. Is anyone know which one is it? Thanks

Asked by: MiloMilo
Honeywell RTH8500 it the best one. I easily installed two. Clear instructions and panel. Works great. Program any temperatures for heat or cool, as long as they are 3 degrees apart. Controlled temperatures are always exactly on target.

How do you change the batteries?

Asked by: Liz2
Pull it straight out and change the batteries. I use Duracell, they last longer and rarely rarely leaks.
Answered by: Brookie

Does this have a lock feature to keep others from changing temp.

Asked by: CRAIG
Not that I know of. I don’t think so. Good thermostat however.

7-Day Universal Touchscreen Programmable Thermostat is rated 4.0 out of 5 by 151.
Rated 5 out of 5 by from I have been very pleased with the performance of this... I have been very pleased with the performance of this thermostat, bought to replace an older programmable thermostat that had less "smarts". I have circulating hot water heat, and no A/C, so I have only tested the heating functionality. The scheduling is very flexible. One significant change from the older unit is that this Honeywell is quite aggressive about getting the temperature up to the set point when coming from a lowered setting (for example, going from Sleep to Wake setting). It really wants to get to the temp you set by the time you specify, so it starts heating quite a bit before the set time. I've found it more economical to tweak the set time later. For example, I get up at 5AM, but the Wake time I've set is 6:30AM. At 5AM, the house is definitely warmer, warm enough to suit me (YMMV!), but it hasn't been running the heat for long while I was still asleep.

We have had this in 4 of our homes. Program 4 time/temperature options (Wake, Leave, Return, Sleep) for each day (7 days) of the week. No having to go back and forth manually between Heat and Air. Saves on energy, keeps entire home at consistent temperature, no cold or hot spots, or cold or hot rooms. Just follow the instructions to make all setting changes so it shows Auto under System and then set to Auto. Absolutely wonderful!!!

Rated 5 out of 5 by from 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!).

At this point I went out to Function Codes and Reset everything. Then I had to reprogram all the temperatures and times in again. Waiting to see this Sunday to see if the schedule goes to Sunday.

Tech support was required to answer one question and while it took over 30 minutes to connect, the tech was knowledgeable and helpful. I would recommend this thermostat without reservation.

NO S1 and S2 for Extra sensors. A downgraded version of a good thermostat with the looks for 19th century. Much better ones out there to consider.

Rated 4 out of 5 by from 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.
