Side by Side Comparison of: Honeywell vs PRO1 IAQ

When you don't want the heat or cool to come on at an appointed time, and you want to control it the way you want it, and don't want to fidget around with a lot of buttons you can't remember which is which - this is the thermostat for you.

I Just Installed Yesterday, Easy to Install, and Just what I wanted. I have been out of the Business, of servicing 8 Years Experience.Honeywell was my Preference. I had to order a Back plate, since the one there a older unit was too Small..

Very pleased with the product. Works SO much better than our old thermostat at keeping a constant temp in our home. Very, very pleased with the purchase. Hubs said it was super easy to install as well.

Perfect no frills thermostat. Keeps extremely accurate temps. Mom loves it. The Thermostat that was installed by her heating and cooling co. was a complete turd. This fixed the problems. No programmable BS, no nothing... just heat when its cold out and AC when it's hot. There is a setting for auto cooling and heating for zones that require this, like desert climates that switch temps from extreme hot to extreme cold, but do not worry about this if you are not in one of those climates... This setting will only be enabled if your furnace is already wired for this action. So if yours is not, you will not even have the option to engage this feature. This should alleviate any concerns that this thermostat is for you or a loved one who is into as simple as possible. My only critique of this thermostat would be that clearly it's target audience is the elderly or people who have difficulty with technology, so why did you make the digital read out so small? It should have been at least an inch larger as there is plenty of room on the face of the thermostat and LCD tech is what? 40 years old now, so it would have added about .01 cents to the cost of manufacture. Anyway, nitpick!

I had an old White Rogers thermostat that was malfunctioning. It was installed in an area where it receives direct sunlight through some overhead windows. Therefore, the thermostat has had an enormous amount of temperature cycles. Over the years, it has caused mine to become extremely inaccurate. Sometimes it would not shut off after the A/C had cooled off the room considerably.I am so glad I purchased this replacement thermostat made by Honewell. This was my first experience with a digital thermostat that includes a backlight. What a great touch to modernize the central air control panel. It was very easy to follow the instructions regarding installation of the thermostat. What I like best is that they have coverplates Honeywell 50002883-001 Coverplate available here on Amazon as well to cover up the footprint left by the previous older thermostat. Most likely these Honeywell thermostats will be bought in unison because the new thermostat is very likely to be smaller than the older thermostat.I removed my old thermostat and made note of all the wires. My existing install had all the wires color coded correctly, so it made installation of the Honeywell thermostat a cinch. This is pretty much plug and play. I opened up the existing holes, installed the anchors and installed the coverplate and mount. After wiring to the backplate, I installed the thermostat and the batteries. The unit powered on as expected and I was able to check out all the options. Very easy to install and use.

This is NOT the most advanced thermostat on the market, so if you are looking for the most advanced, this isn't it. But after the other trash one i had installed was gone, i was very happy with this because it was exactly what i was looking for. This thing has GOOD instructions, and while it has many options to set on the initial start-up the instructions are very informative. For my heating system it was a simple install of 2 wires and mount (My home has a Forced Air Heating System). Depending on things like if its gas or electric, you may have a few more wires to hook up, but i found that the back of the device was also marked clearly and i assume it would not be much more difficult to instal a few more wires. My Heater responds instantly from the commands on the thermostat, whereas my old one would lag for about 30 seconds before a response. This is NOT programmable, so if you just want a simple set temp and go, this is the one for you. The battery compartment is easy to access and remove to change batteries.The only functions on it are:1- adjust temperature2- toggle ON/OFF of your heating system3- toggle manual / auto setting on your fan (manual is more like ON since manual just turns fan ON until it's stopped)Note - I do not have air conditioning built into my system so have no idea if you did have that installed if the toggle on/off of your heating system may automatically activate your A/C or not.Conclusion - If you would like simple well built Thermostat that will do what it is suppose to if installed correctly I could not recommend one more than this.

I really like this thermostat. We had the manual version for about 4 years and it was good but we really wanted this version where you can setup everything under the auto setting. Installation was very easy and everything worked great from the start. Even setting up the programming was easier than what I expected. If you follow the directions exactly as they have it, you can go wrong.

Exactly as described - a simple, clean, non-programmable thermostat. Unlike some others, this model displays both the set temperature and the current temperature. Many of the other inexpensive programmable thermostats only display the set point. The display is clear and the backlight is effective.

We chose this thermostat because there are usually people in the house and we don't the extra expense and hassle of a programmable thermostat. We were also looking for one that didn't automatically switch back and forth from heat to cool. It's too expensive and wasteful to run the opposite unit just for an hour or two of temperatures beyond the preset comfort range and those days are quite numerous in north Texas.This thermostat is working quite well and was very easy to install ourselves, but we were replacing a similar Honeywell thermostat that only lasted about four years. I hope, but don't really expect, that this one will last longer. I still gave it four stars because it's inexpensive and easy to replace.

It works well enough that I am not returning it, but there is no way to set the number of degrees of 'deadband'. In my case, the number of degrees looks like 1, so my furnace is cycling more frequently than with my old thermostat. I sense I am wasting money because of this. I'll probably call their support when I get irritated enough.

Installation can be confusing depending on the thermostat you are replacing. I replaced an old mercury thermostat and had to use Google a few times to be sure I wasn't making mistakes. Aside from the confusing wiring situation, installation was fairly easy. With my old thermostat my (propane) package unit would run fairly often, usually with cool to luke warm air. With the new thermostat I get warmer air for shorter periods of time. Love the digital readout, my mercury thermostat was not at all accurate, which is why I had to replace it. My only concern is being uncertain of how accurate it is. The readout on my thermostat and my space heater are usually about 3 degrees apart (with the thermostat saying it's 3 degrees warmer than the space heater says).

It was easy to install, and it does just what it says it does. Note that the "auto" (i.e., the ability to automatically go from "heat" to "cool") is not enabled by default, so you need to go into the setup mode to enable it. It makes something of a "click" noise whenever it kicks on the A/C or furnace. That doesn't bother me, but some might find it annoying.My wife wishes, in retrospect, that we had gone for a programmable one - but I've always found those to be such a pain to program that I never bothered. (Lesson: Check with spouse before deciding!)

We've been using this thermostat for 4 months, and so far so good. It looks nice on the wall and it is accurate.UPDATE: After 10 months, we began to have trouble with this thermostat. The temperature indicated is not the temperature of the room. We had the room set at 67 and it was actually 81 degrees. It almost seems to "Stick" sometimes and then it starts working again. I am afraid to see the gas bill this month!

Promised that you didn't have to manually switch back and forth from cool to heat mode. While it's true this thermostat can do that, the instructions recommended not using that feature if the outside temperature falls below 50 degrees. To turn on/off this auto switch mode requires a multi step process, so it seems easier to just manually switch from cool and heat myself. Otherwise, it's a perfectly functional thermostat. I don't notice any benefits or drawbacks compared to any other thermostat I've used.

The wiring in my old thermostat and this Honeywell were different, the manual failed to explain it, and I couldn't figure it out. So I called the 800 number and asked for help. The man who "helped" me was the rudest person I've dealt with over the phone in years. He spoke down to me in a very brusque manner, wouldn't let me explain to him what the problem was and, in general, treated me very poorly. While he was lecturing me, I figured it out myself, and when I told him what the problem was, he said, "Oh, I was getting ready to explain that to you, but you kept interrupting me." Right!!!I wrote to Honeywell's corporate office and have yet to receive an answer.The thermostat is fine - inexpensive, works well and I'm happy with it. Just be forewarned if you need help with the installation, you may be treated like crap! BTW, the instructions are not well done. There are a few important steps missing.

lasted less then 1 year woke up this morning could not shut off heater off or a/c had to turn breaker off and when I turned breaker back on it would start all by itself just ordered a new one had to go with one day delivery its getting hot here. last time I order one.

The unit is simple to operate and works fine but I really was looking for a display that lit up well at night and the picture in the catalog looked to clear and sharp but the display in reality is dim and not very readable. That is my only issue with this unit.

I purchased this item for its advertised visibility. As noted by other reviews the background lighting isn't even close to what is depicted on the packaging. In my opinion that verges on Deceptive Advertising. It performs as stated but doesn't help my poor aging eyes. Too bad the background isn't brighter.Honeywell shame on you.

the description is misleading, it says it has an easy to read backlit display and on the picture it is shown to be brightly lit. I have 20/20 vision and can hardly read it. The display is dim and the numbers are small. The temperature control is good

Purchased this to replace a thermostat that required batteries, no where in the description did it say that it needed batteries. After receiving this thermostat an opening package, I discovered that it required two batteries. Now I am stuck with a thermostat that I don't want or need and out with the cost. I feel like I was mislead by not mentioning that it required batteries in the description. I am sure that it is a good thermostat, but it is not what I thought I was getting.

Not compatible with the unit in my apartment.

This thermostat did not work with my unit.

This lasted all of 2 years...

Purchased without reading directions carefully. Will NOT WORK with heat pump WITH auxillary heat (2-heat, 1-cool). However, the reason for the bad review is that I called honeywell's 800# that comes with the unit. The guy struggled with English, placed me on hold several, several times. Then returned to ask Where I bought this and When....because he said, this very unit is now OBSOLETE. He stated that they no longer manufacture or service this thermostat.

Failed in 4 months

Did not work for our system

We bought this product in January, and the return policy was for 30 days. The end of February was our 30 days. When we first received it, the screen acted up, but I ignored it. Now, just a few weeks after the return time is up, the screen is completely messed up. We can no longer use this item! Not happy at all!!

Temp reading off by 8 deg. Thermostat set around 68 and this is showing 76. Honeywell brand doesn't guarantee anything.

Stopped working after a few months. I had to purchase a new one from a HVAC company who came to repair my AC.

Supposed to be a universal unit, but it doesn't work on my system, so it was a complete waste of money and time. Had to buy an OEM unit.
