I bought this to replace a White-Rodgers non-programmable thermostat (it looks like this one: [...] This product is a fine replacement.

I bought my house with an 80% efficiency gas heater installed (Trane, around 7 years old), but no air conditioning. Around a month ago, I had air conditioning installed (Carrier). The non-programmable thermostat became a bit annoying because it got too hot during the day and too cold at night, depending which direction I changed the temperature.

I took a look at the old White-Rodgers thermostat and had the following connections: white to W, red to RH, a red jumper from RH to RC, blue to C, green to G, and yellow to Y. (A very good reference for what those all mean is [...]

The Honeywell unit does not have an RH terminal, only an R and an RC. I assume R, RH, and RC are all the same (at least in this situation), but not wanting to start a fire or something, I called the customer support number and was incredibly surprised to find that the person I spoke with was actually able to help me.

Turns out--and please don't blame me if it breaks your system--that red goes to R on the new unit and the jumper between R and RC (there by default) remains in place.

Minor annoyance: the Honeywell *requires* batteries. The White-Rodgers unit operated without batteries (the person I spoke to told me the blue wire, C, supplies power). Since the Honeywell doesn't take a C connection, it must run on batteries. (Hopefully they last a couple of months at least.)

My final connections: white to W, red to R, jumper from R to RC, green to G, and yellow to Y.

One more minor annoyance: you'll need an incredibly tiny flathead screwdriver to tighten the terminal connections. If you have an eyeglass screwdriver or similar (and know where it is), you'll be fine.

Otherwise, I'm very happy with the unit and Honeywell's phone support.

I bought this at a local Menards store with assistance of the staff. I replaced an old round Honeywell mercury-switch model. Have the typical 2-wire setup for a very ancient (40 years old?) natural gas forced hot air furnace. I decided to squeeze some savings on the gas bill by lowering the temperature during the workday when I'm never home for 9 hours, and also drop temperature overnight as I like it cooler while I sleep.

Installation was a breeze. I work as an office equipment service tech, so I did not expect any trouble figuring it out, your mileage may vary in that regard though. I had the required small screwdrivers on hand. The mounting template perfectly matched the old round thermostat, so I just reused the old screws in the original holes in the wall. As I customarily do, I did read the installation and setup directions prior to installation.

Programming was also fairly easy. What you have to understand here is that there are 4 adjustable times of the day where the temperature can be allowed to change. Exactly what the amount I needed for my purposes. If you wish for fewer adjustments, just set 2 or more of the consecutive time events to be the same temperature. This is how I handled the weekend program, as I only wanted to lower the temperature at bedtime and raise again in the morning. I left the "away" and "home" at the same temperature as the "wake" setting to accomplish that. Again, you can adjust the time of day for these events in 15 minute increments. I did not see anything confusing about this other than I would forget to push the set button and think I was adjusting the temperature, and instead was changing the time. The numbers being adjusted flash, so that was just me not being observant.

I had a really basic thermostat that I was replacing. One of the round ones with the mercury switch inside. (Made by Honeywell, I might add). Once removed, just two wires came out of the wall. When you touch the two wires together, the furnace comes on, and when you keep them apart the furnace is off. Couldn't be simpler.

But can you imagine that this thermostat doesn't have instructions for that scenario? I was able to Google instructions eventually, but it is ridiculous that it describes what to do if you have 5 different colored wires but not what to do if you have only two. By the way, what you had to do was remove a jumper and attach your two wires to the CORRECT two posts, which I no longer recall. After that the thermostat works fine, but it was unnecessarily complicated for such a simple use case.

I did end up buying a second one, for the upstairs.

I bought this model to replace my old, hard-to-program thermostat. Very simple. Easy to install. Easy to program. Did it all in lessthan a half hour. Very precise temperature control. Maintains temperature to 1 degree. Wherein, there is the rub.
When they say maintains temperature to +/- 1 degree, they mean 1 degree. At whatever temperature you set, if your room temperature changes by 1 degree, your furnace goes on. When it recovers that 1 degree, it shuts off. I have seen my furnace go on and run for three minutes and shut off. Three minutes later, it goes on again and repeats the cycle. It does this continuously until the next set-back.
My electric bill has gone up 50% due to the frequent cycling, and my gas bill went up 30%. All due to the frequent cycling of the system.
I suggest you opt for a thermostat that has a 2-3 degree cycle range. It will still maintain a comfortable temperature without running as frequently.
