Side by Side Comparison of: Honeywell

This is an excellent programmable thermostat which does its job without fancy bells and whistles. WiFi enabled thermostats are not secure yet and are subject to hacking. IoT is still evolving and will get better, just not today.

It was a direct replacement for my 7400 that recently died. I didn't even have to rewire anything. I just took off the 7400 faceplate and put this new 7500 in its place. Great!

A dependable programmable thermostat with backlight. This economical digital unit can replace most other units but because of the many combinations of wiring on homes, it is recommended that buyer call the Honeywell toll free number to have the assistant walk the buyer through the correct wire connections. DO NOT assume the color of the wires will guide you to making the correct connections. Once installed (which is quite easy) user may use the factory default settings for energy efficiency or set his/her own settings. Unit has multiple daily settings and battery backup (two AA batteries) that will last about two years before replacement. This unit is a good buy for the money.

I'm not an expert in thermostats, but compared to the one we had when we moved in the house that could only change the temperature and turn the heat off and on, I really like this one. I wanted a 7 day programmable 'stat and that's what this is. Can't tell you about installation because a family friend electrician did it for us, but it seemed easy enough. There's no light until you hit a button, which I guess would be my only gripe, but since it's programmed, I really don't touch it. Easy to program, love that I can have the temp change from low overnight to warm when we wake, then back down when we leave for work then back up before we get home and low again for sleeping. I just wanted a simple thermostat, I don't need digital everything, on my iphone and all that, there's enough technology in my life that my thermostat does not need to be one of them. If you want simple, easy to use, I recommend this.

There was a little difficulty in installing. Be sure to label the wires before pulling off the old thermostat. We were surprised to find that our old thermostat was registering several degrees lower than the actual temperature. Here we thought we were being so good keeping the house at 64 and being perfectly comfortable!! We found out after installing the new unit that what we thought was 64 was actually closer to 67 and 68...out come the sweaters. We have not programmed it, we use the hold feature. We find that our schedule is too unpredictable to know exactly when we want the heater to turn on. So we manually turn it down to 59 at night and back up to 66 in the morning. The light on the display is very nice, no more turning on the hall light blinding ourselves to adjust the temperature.

I purchased a Honeywell Thermostat at Costco that stated it would work with a Heat Pump what I didn't know was it wasn't for a Heat Pump w/ Emergency Heat. After uninstalling and reinstalling my old mercury type thermostat I was wanting a thermostat that would work. After researching the reviews and checking Amazon I settled on the RTH7500D as it would hopefully handle the emergency heat. Being computer literate I like the ability to pre-program the temperature by simply checking each of the days and doing a single programming for both heat and cool. The thermostat has a 3 degree changeover to automatically switch from heat to cool during the temperate weather in the spring and fall. My wife especially likes the automatic temperature reduction at night without having to get up to lower the thermostat. Not so simple install due to wires attached to the old thermostat were not connected correctly. If I had done it again I would have traced the wire colors back to the air handler and confirmed. Turned out my brown wire connected to the emergency heat on the old thermostat was actually a common that fried my transformer when the emergency heat was turned on, lesson learned. Normally, using the conversion instructions from the out thermostat to the new should work. I stopped by the auto parts store and bought a 3 AMP mini fuse to put on the new transformer and started again (fuses are cheaper then transformers). It was an easy install once I knew the actual color code for each wire.

This is a great thermostat and is very accurate. Very easy to install and easy to configure. The only reason I did not give it 5 stars is because you cannot adjust the number of degrees before it kicks in. It will turn on as soon as it is 1 degree away from the specified temperature. This results in it turning on very frequently. Surprisingly, however, that doesn't seem to correspond to any additional use in electricity.Some notable nice features are:Filter change reminder.Smart control that allows it to shift from heat to cool depending on what it detects. This is really nice since our weather can sometimes still be warm at night, or sometimes cold. It will detect whether it should be cooling things down or warming things up. Quite frequently, it will turn on the AC when we go to bed, because it is still warm, but then will switch to heat when the temps drop overnight.Very low battery consumption. The light turns off when you are not adjusting things and it just sips power like a very basic thermostat.Fool-proof wiring. It is very clear how to connect the wires for several types of HVAC setups, even including radiators.This is an EXCELLENT choice if you want some nice features but want to save some money. I wouldn't be surprised if this is a "loss-leader" to get you interested in smarter thermostats from Honeywell.

Despite some comments, it's actually very easy to install. No it didn't take 15 min, more like 20. The menu to change settings is the worst part. Instead of being able to scroll through menu items you have to have the manual handy with what the codes mean and scroll through codes to get to things like day light savings, day changes (I made a mistake on initial install) . If you're looking for a cheap way to automate your heater, this is it!

I've owned 3 of these now. Years ago when I bought my first, this was the fanciest consumer model I could find and it was easily a 5 star device. Nowadays, it's pretty dated and has a couple flaws that haven't been addressed. It's still worthwhile if you can get it at a discount (My most recent one came "Used / Like New" from Amazon Marketplace.)To keep this brief, check out the 5-star reviews to see what's so good about this thermostat. I'll just quickly list the shortcomings that cost it stars IMO.1. The pins on the back breakThere are pins on the back of the face that connect the thermostat to the wall mount's electricals. Eventually you'll have to change the batteries. When you take off and replace the thermostat face from the wall mount, you need to be VERY CAREFUL that everything is lined up and pushed on straight. With the pressure it takes to snap the face into the clips, you (or your teenage son or the hamfisted AC contractor you hired) might not notice you're breaking off a pin on the back. The penalty for the mistake is that you have to buy a new thermostat. Yes, this happened to me.It's pretty clear to me this is a design flaw. There are at least 3 changes that would alleviate this:a. Allow access to the batteries without removing the face. Even our older Honeywell RTH6300B has this.b. Implement a less troublesome pin arrangement. Again, the RTH6300B has a set up that's much easier to align, IMO.c. Connect the face and wall mount with a ribbon cable or short wire bundle instead of direct pin connections. That way you can connect the two with more care while they're still apart and you can take off the face without disconnecting the electricals at all.This is worth at least one star.2. Feature set is getting datedThere was a time when this was one of the top thermostats in terms of features. But now there are devices that do it better and point out the shortcomings with the RTH7500D. Physically, the buttons are clunky to press. Programming is quick enough for minor changes from the defaults, but a chore for very specific schedules. Programming flexibility is pretty lacking. For one, your heat and cool schedules have to be the same. Meaning if you want heat from 6am-8am weekdays during the winter, but cooling from 7am - 8am in the summer, this isn't supported - you have to reprogram each season. For two, is 4-period "wake / leave / return / sleep" model really the best? The reason I'm replacing our 5-2 day RTH6300B with this 7-day RTH7500D is because we have cleaners come once a week and we keep forgetting to leave the heat & AC on for them. On those days, we really have "wake / leave / cleaners arrive / cleaners leave / return / sleep".To compare, I'd point you to the cheaper "GE 15089 7-Day Digital Outlet Timer" (which I also own). Though it's not a thermostat, it allows you to program 7-day automated schedules by pushing little rubber buttons, just like the RTH7500D. The Honeywell is perfectly usable but, IMO, the GE 15089 does it much better and shows what's possible.3. Retail price is now "high" for the feature setWhen this was a top thermostat, it was worth the price. The retail price hasn't come down enough to keep it competitive. IMO, the price determines whether the above feature issues are worth docking a star or not. Fortunately there are plenty of channels like Amazon Marketplace where you can get a new (or nearly-new) RTH7500D for a significant discount. If you have to pay full price, keep in mind you could have this thermostat longer than you have your car or fridge (if you don't break the pins on it) so you might as well get something better.4. Problems with some HVAC systemsI've never had any problems but I've never had a fancy 3-stage+ heat pump system. Go check the 1-star reviews before you buy, and take advantage of your return window.Keep in mind, I like this thermostat (obviously - it's my 3rd). It was once great and is still pretty good - just not for the retail price.

These are pretty easy to install and set up. If you grew up setting VCR clocks or watches with two buttons, you will find programming this device easier by far. On the other hand, if those sorts of things make your crazy, then this is not the thermostat for you.Some of the subtler controls such as "recovery" and some of the heating system options could be better documented. For example, what exactly changes when you tell it you have a high efficiency boiler? The heating system in my house is quite odd. It's an under-floor hydronic system with heat from a domestic hot water heater. I'd like to know what settings for this would be best for operating that kind of system, but I really can't tell.Nevertheless, the settings I've chosen work well enough. When the temps in the room is below the set temp, the heat comes on. Since this is what all thermostats do, I wonder what all those extra configuration settings are even for.Anyway, long story, I have two of these and they work fine. I wish they were physically closer to the wall (the mounting bracket makes them protrude a bit) but otherwise they're fine.

As other reviews have mentioned, you have to really take your time with reading all the steps in the manual for programming, not because it is so difficult, but because it takes awhile to understand the overview of the way this thing is programmed and functions. However, once you do, it is VERY good, and and accurate. Warning though - DON"T accidently forget to enter the proper day of the week when you first start loading in the data. It is almost impossible to change later! Still, very worth the money and does exactly what it says it does. An excellent buy.

We mostly bought this thermostat because we needed the auxiliary heat capability. Our old one of a different brand simply quit working on us one day. This one does everything I need it to do.The scheduling feature works well although it can be a little bit of a hassle to do. But we didn't buy it for that and hardly use it so I don't complain. I would like it if it had a vacation feature but when I leave town I just use the schedule so it will keep my house cooler in the winter or warmer in the summer until shortly before I return. That allows me to save energy while still saving energy.As an update, one thing I didn't realize when I bought it was that it didn't have an input for a thermostat going to outside. So it doesn't read outside temperature. This means that it doesn't switch to auxiliary head automatically when it gets extra cold outside. Our old one did, but our old one randomly died. This isn't a deal breaker. We just have to manually switch it to auxiliary heat when it's particularly cold since our auxiliary heat is more efficient at colder outside temperatures.

Batteries loose contact frequently when adjusting thermostat. Pain to repeatidly jiggle unit to regain contact. Difficult to open to get to batteries.Programming could be easier.

Too tedious to program. I had the touch screen version which died after a year and so I went to a simpler model but it's such a pain to program, my as easy as the later models.

Functionally it is fine. The programming interface is rather clunky but at least you can go back and forth without having to cycle though all the steps if you make a mistake.Unfortunately, the buttons are terrible. They are made of a somewhat squishy rubber with considerable travel and they only register with substantial pressure, sometimes having to be wiggled a bit to be recognized. Worse is if you use enough pressure, the edge can get stuck behind the faceplate and remain stuck until you pry it.When I ordered, I didn't care about touchscreen versus buttons but had I known the buttons and the trigger sensors were this bad, I would have gotten the touchscreen version.

Not apparent when purchased, but after installation I find that there is no function to simply turn house fan on to circulate air. My old non-digital unit had a "fan" switch to do so and could then circulate the cool air from downstairs up throughout the house. This unit's instructions ask you a few questions about your set up like "do you have an air-conditioner" and "do you have a separate heat pump". Your answers to these questions determine what settings will display on the units LCD screen — presumably so you don't have options to adjust things that you don't actually have in your house system. Maybe during this process a "fan on/off" setting was removed from displaying on the LCD screen, but tracking that down and testing that theory will involve more than i should have to deal with.

I dont like it, it not hard to set it up, but the one i got was broken and few times at night will drop the temperature in the room to 60 and we live in Chicago area. Frizzing cold for me. I call Honyewell and the guys are very help full, but i was not able to return mine so i have to buy a new one. Honywell offer to sand me a new one for free, but i just want a simple one now so i dont have to run @ the same problem.

The RTH7500 was fairly easy to install but the screen went blank in less than 6 months. We replaced the batteries three times and nothing! It is supposed to have a one year warranty! We contacted Honeywell customer care and after several phone calls and emails dragging out for over three weeks,we still do not have the issue resolved! Glad I kept the old thermostat! The worst customer service I have ever dealt with! Bye Bye Honeywell!

Did not work and I return it.

The window to read the numbers on the thermostat is dirty and looks like it has dust in it. I can't wipe it off. Looks terrible!!

I bought this unit two months ago at the end of January 2016. The unit started glitching out over the past 3-4 weeks. Unfortunately I'm past the return window and I'm pretty pissed about that. The screen started going blank until I pressed a button. The current temperature display was always equal to the set temperature and never changed. Despite those display issues it still seemed to turn the boiler on and off as programmed. The final straw however was this morning when the heat never turned on and my house was a frigid 58 degrees. Judging by the other reviews seems like you have a 10%-16% chance of receiving a defective unit. If you don't like to gamble with your pipes freezing do not buy this thermostat.

Horrendous customer service with Honeywell- "high call volumes, we're unable to answer your call at this time- please try again in future. CLICK". Seriously?!?!Tried Honeywell again different division- "I'll transfer you" call dropped CLICK. Tried Honeywell again as a "rotary 'phone user" and rcvd "no one available to take your call" CLICK.Can't get this pos to heat house above 62 degrees! Seriously?!Utter Crap!

The video for this item advertises that it is easy to use and program. I found it difficult to program. After finally getting it installed. I had to call Honeywell cusomer service to get help with programming that was not covered in the inadequate owner manual that came with the T-stat. After managing to enter the progams, the unit operated for a few days. Then the programs did not hold and the process had to be repeated. After the third attempt I have concluded the T-stat was malfunctioning and I took it off the wall to be returned. I found that the screen is difficult to read what with all the numbers, boxes, etc. I would not recommend the RTH7500 at all!

I bought 2 of these units to replace existing thermostats that were 25 years old. Physical installation was easy, but program set-up did not work. Called Honeywell tech support. Got connected to an Asian call center, where reception was poor and the agent was not understandable (incomprehensible English}. After several minutes of frustration, I asked to be connected to a US call center. Agent refused and said I should just return the units to the vendor. Honeywell should be ashamed of this type of service.
