Customer Reviews
I purchased two of these thermostats through the Amazon website and installed them just before the start of the Memorial Day weekend. I am very pleased with both thermostats, but I did encounter a problem during the install of the upstairs thermostat. Although I had flipped the breakers labeled for the upstairs and downstairs heat pumps to the off position at the panel, the upstairs heat pump was still receiving power, because I blew a fuse in the heat pump during the install. Obviously this problem was caused by a lack of due diligence on my part - ensuring that the power to the heat pump and to the thermostat was really off. My wife and I went without air conditioning to the upstairs of our home for approximately 30 hours before a service technician arrived to find and replace the blown fuse.If you have a volt ohm meter, I suggest that you verify that there is no power to the thermostat prior to the install. In doing the install yourself, you may find that you are at the mercy of the wiring provided for your old thermostat. For example, on our old downstairs thermostat, there was no common wire. When the heat pump (air conditioner) is on, the lead for the furnace is used as the common. When the furnace is on, then the wire for the air-conditioning is used as the common. Without a common lead as a reference, it was not possible to measure the voltage to our downstairs thermostat when neither the air conditioner nor the furnace is running. This led us to believe that we had no power to the thermostat even after we had switched the breaker back to the on position after the install. However, the thermostat worked fine. The service technician explained to us that in the original wiring to our old thermostat, the common was missing and that was why we could not measure the voltage.I called the Honeywell support number on the back of the thermostat installation manual, and a technician located in New Deli answered immediately. The technician was friendly and knowledgeable.Two messages that may appear on the thermostat after you install it may lead you to think you have made a mistake when nothing is wrong. First, if you have a heat pump and the word "Wait" appears on the thermostat display after turning the heat pump back on, then this is normal. As a precaution the thermostat waits five minutes before cycling the heat pump back up after it has been turned off. Second, if the word "Recovery" appears on the display when you first turn the furnace or air conditioner on, this simply means that you have the Smart Response Technology set to on, and your thermostat has turned on you air conditioner or furnace to reach the target temperature that you set in the schedule.With my old mercury-based thermostats, I could not be certain that the correct temperature was displayed. Nor could I be certain of the actual temperature that I was setting the thermostat to. If I left the thermostat set to a high setting while we were away on summer days, then the house would not cool off before bed time after we got home. All of these problems are solved by our two programmable Honeywell thermostats, and I saved over $40.00 by buying the thermostats through Amazon rather than Home Depot.
Easy to install and programming buttons are easy to understand. It is the display that is difficult to understand. Be very careful about the check mark before the days of the week. When you make a temperature input it will apply to EVERY day that has a check mark and erase what you previously inputted. You have to cycle through the days twice to eliminate the CHECK marks for the other days to enter in data for just one day.There is room on the display to show you all your heating or cooling temperature settings for each day of the week, but they neglected to provide this so it is very difficult to review your inputs to be sure they are right and to correct for CHECK mark errors from above.
This review is from the perspective of a novice. I replaced an 11-year-old thermostat with this one yesterday morning.Installation was not a breeze as the claim on the product package would like you to believe (i.e., "designed to install in 15 minutes or less.") We have a 5-ton split central unit with the condenser outside of the house, and the coil and a gas furnace in the attic. Matching the wires to the new thermostat was not that straightforward. Our old system has 5 wires but the Intallation Guide only shows an example with 4 wires. After failing a few configurations, I finally gave up and called for technical support. The puzzle was then resolved.Programming was mostly simple and easy but not always intuitive. You do need to read the Manual to figure a number of things out. An alternative may be the 8500 Touchscreen model, which seems to have more intuitive programming based on reviews from Amazon users.Overall, I would recommend this thermostat. Just make sure that you do your installation during office hours when technical support is available from Honeywell.
First the negative...The Installation Guide needs revision. I spoke to Honeywell about this and other complaints and hopefully these issues will be changed. BTW, they were very nice.First problem: To set the system preferences is says to press the left button and then hold the middle button down for 5 seconds. It didn't work. It will work on older models, but on the newer ones they changed the operation of the unit so that pressing a button first turns on the backlight. Once the backlight is on, then press the buttons again to get the desired response. This isn't mentioned in the manual.Second problem: Since I am retired, I don't need the "Leave" and "Return" settings. There is no way to cancel these. Of course, you can set the time for these to match the "Wake" and "Sleep" times, it just seems like added work and is not intuitive. Some of the lower priced models have the ability to cancel these settings.Okay, now for the good...1) It keeps the temperature very consistent compared to my old thermostat.2) If I want to change the temperature I can do so and the programed schedule will still function normally at the next preset time, or I can put the temp change on permanent hold. This is great for those days that your bones feel a little colder than normal.3) The display is bright and clear. I like being able to see the actual and set temps at the same time.4) Once the unit is set up, operation is very simple.5) For those that need it, it can automatically run your heat and cooling through the day to keep your temperature at a constant setting. Think Hot days and Cold nights! I suppose you could also use this to lower the temperature at night for better sleeping.6) The Smart Response Technology allows you to wake up to the temperature that you want or to go to sleep at lower temperatures.7) This unit gets its power from the furnace and only uses the battery as a backup. This eliminates the worry about having the battery die while you are away for a protracted period of time in the winter. I'm not sure why this would need a battery back up because if it looses power, it's because your furnace has also lost power. I suppose it's for people that want this controller, but don't have the right wires available from the furnace to power it. It also has a lithium battery to protect its memory?8) This unit also has automatic daylight savings time adjustments.Summation...All in all, I really like this thermostat and would recommend it to anyone or everyone. I'm glad I bought it.If you don't mind just running off of batteries or don't need 7 day programming, the lower price models are also very nice.
This is a Honeywell 7-day programmable thermostat. What this means is it allows you to control individually the temperatures (up to four times / changes per day) for each day. Some others group Mon-Fri together which is okay if you're a 9-5er M-F. What about folks on Weekend shifts and the like? This is your stat! Each day in the program window can be set independently or can be grouped if you wish. It allows you set a "Wake" time and 2 temps (1 for heat, 1 for cool), a "Leave" time and 2 temps, a "Return" time and 2 temps, and a "Sleep" time and 2 temps. You can turn off any of these if you wish for days your typically home all day or gone all day. The program sets time to the quarter hour and each temp to the degree. The setup allows you to turn on or off a nice feature of this stat which is automatic switch over. If you have both heat and A/C on your homes HVAC system it can automatically change from heat to cool or back if the tem shifts more than 3 degrees (I might be wrong there it might be 5 degrees.) in the wrong direction. So for instance your thermostat is currently in heat mode and is set to 68. Obviously if the temp drops below 68 it will turn on your furnace or heat pump and begin to heat. However in this example it's April and it gets warmer in the afternoon. The house temp hits 74, so the thermostat will change the cycle to cool and run the A/C. You don't have to use this feature but it is nice for those Spring mornings and afternoons in the Midwest. One more point of clarification it might be three degrees over your "Cool" setting for the changeover. The interface and display is easy to use. It's a simple five button control. Two up and down arrow keys to change the temporary heat or cool setting from the main screen or to change temps and values in the menu screens. There are three hot keys. From the main menu you have "System & Fan", "Schedule", and "Clock & More". The system and fan lets you select your mode (heat, cool, or off), as well as your fan mode (auto or "always" on). The fan selection will also let you run the fan even if the system is in "off" mode which could be nice just to circulate air thru your home. Schedule let's you change your scheduled times I talked about above for each day. This is where this thermostat pays for itself. You can have it "turn up" the power (making it warmer in a cold season or cooler in a hot season) just before you wake up, and then "turn down" when you leave; back up again just before you normally come home and then down again after you go to bed. That way you're not wasting money paying for heating and cooling you're not going to notice. The last hot key simply lets you set the clock. When you change the temp from the main screen it shows temporary on the screen. It will revert back the next time a scheduled change occurs. Or you get an option thru a hot key to permanently hold the temp until you hit a hot key that says "Use Schedule."This thermostat requires two AA batteries. The instructions say this unit actually runs off of the 24V AC power provided by the home's Furnace or Air Handler and the batteries are just for backup in case of power loss. This stat should work for nearly all typical furnace and A/C combos. It will also work for standalone furnaces as well as standalone A/C blower units. In the setup you get many options for configurations. Gas heat, High Efficiency Gas Heat, blower-less gas furnace, Electric Heat Pump, Electric Heat Pump w/ emergency heat OR Aux heat, A/C, ect. Configurations that I see no mention of are boilers and multistage heat like the modern gas furnace-heat pump combos. However if you have typical furnace & A/C setup or heat pump setup this unit should work for you. The instructions also come with a wiring guide. Typical installations will be 4 or 5 wire installs. The instructions have a guide to identify each wire and instructions on where to connect it. Also I've contacted Honeywell's tech help line and they're very helpful and informative.I've installed three of these units so far. The first was in my home that has a typical gas furnace-A/C compressor split system. It's worked well the last three years and I have noticed the saving on my gas and electric bills. I decided to put one my parents house that has a furnace only two years ago. That was a simple two wire setup. As crazy as it sounds last summer I also put one in my travel trailer (RV. It required a little research as to how to wire it. But with a little help from my previous thermostat's wiring guide I figured it out. So I can confirm it will work with a Dometic A/C unit and Suburban propane furnace. In this configuration you still have two wires for a furnace. It activates in heat mode and my furnace blower works fine. This is also the reason I decided to install an electronic thermostat. The old analog units were really inaccurate and left you fiddling with it constantly. Also I can save my propane in those spring and fall trips when I'm normally away from the trailer thru the day. The A/C took a little more research. It is an non-typical three wire install. I found that Dometic uses an A/C wire and then a (low) fan wire and a high-fan wire. The high-fan wire on the old stat had an "on-off" switch built into the circuit. There are instructions on the web how to install a switch to preserve this feature but I never used low fan so the easiest way is to wire both the fan and high-fan wires into the fan connector on the thermostat. This is the way the circuit was wired in the old stat with the high-fan switch closed or in other words in the "on" position. Other RV equipment manufactures wire their equipment differently as do some newer and older models of Dometic so RESEARCH this install first if you wish to attempt it. When cool mode is activated it turns on the rooftop A/C unit and blower just fine. I have had ZERO problems thus far. One more thing, Honeywell does not support this install, so their tech line will not be able to help you. Ironically this is where I've noticed the most impressive savings. Certainly not cost wise, but in terms of not having to refill my propane tanks as often. So far it's really impressing me. On a side note you can still use the "fan only" setting by turning the thermostat to "off" and turning the fan to "on". My roof top blower kicks on in high mode. Nice in those sping and fall afternoons to open a couple of windows and circulate the air.All in all, Honeywell makes a great set of products. These will keep you more comfortable than an old analog thermostat and save you money. It's a win-win. I can't sing enough praises about how well these units work!UPDATE 9-26-2011:I've decided to leave the original review intact as to avoid confusion. However I need to correct and clearify a few things. First, about the physical capabilities of this unit. It IS capable of working with Hybrid-split systems (that is to say with modern gas furnace-heat pump combos) as well as boilers / fanless hot water systems. I appologize for getting that wrong. Also it has the capability to work with new two stage heating and cooling systems. These use two wires each for either OR both heating and cooling. So for instance if you believe you have two stage heating you're old stat should have connections labeled "W1" and "W2" as apposed to a standard furnace having just "W". If you have two stage cooling, you will likely have "Y1" and "Y2" as apposed to just "Y". These systems are pretty uncommon but I thought I would add this in case you are a person looking for a replacement thermostat for such a system. However if you are certain you have a two stage heating or cooling system and it does not have mulitple wires for the side of the system that is multistage, contact the manufacturer. To give a little carity I will include the connections that MOST standard gas furnace and A/C combos will use. RH (or just R) and RC, generally these use a common (same) wire and most replacement thermostats have a preinstalled jumper (this one does as well. This provides power to the thermostat from the furnace. If you have seperate RH and RC wires, remove this jumper. "W" sends a signal to the furnace to turn on the heating element / burner. "Y" is the signal wire for the system to turn on the A/C compressor. "G" is the signal wire to turn on the fan / blower. These are the 4 or 5 wires I mensioned in my original review. Also, if you're using a heat pump instead of a gas furnace, you will likely have an "O" or a "B" wire inplace of a "W".A couple of other things. As I mensioned this thermostat has an automatic change over feature to allow it to switch between heating and cooling modes automatically. If used, this feature will make the system pretty much hands free requiring almost no user input at all beyond setting the temps. As I mensioned above there is a "3 degree seperation" required by the thermostat. I wasn't sure what this was but after re-reading the instructions basically it amounts to simply requiring that the heat temp setting is a minimum of 3 degrees below the cool temp setting. So if you have you're cool temperature set to 72, and the closest you're heat setting can be is 69. If you turn up the heat setting to 70, it will bump the cool setting to 73. However there's nothing stopping you from having a much more realistic 5 or even 10 degree gap between them. Basically if the temp rises above the cool setting the A/C kicks on, if it drops below the heat setting the furnace (or heat pump) turns on, if the temp is in between the two the system sits idle. I hope this carifys any confusion I migt have created with my original review. All-in-all, this is still the BEST digital or replacement thermostat you can buy. A tremendous value, that for both flexibility and saving you money is well worth a 5 star rating!
I didn't give it 5 stars only because I've only had this thermostat running for 3 weeks now with no hiccups. It's fairly easy to program for each day of the week and can have multiple daily start/stop times, too. I started by opening up the old thermostat while it was operational, writing down all the wire connections,(I had 8) and then emailing that info to Honeywell tech support. They responded within 2 days with the correct wiring for the RTH7500. Installing was easy. Make sure the power is off to the compressor/pump and no voltages are on any of the wires before you install this thermostat. Also, if there is a big hole where the wires come through the wall, make sure you plug it up as best as you can. This could cause your thermostat to turn on more than it should. Hopefully it will have paid for itself by the end of winter.
Thermostat is easy to install and programming was not difficult. The instructions are clear and easy to follow. Thermostat works well, no problems. My only complaint is that the display backlight (the real reason I bought this thermostat: to be able to see it in the dark without turning on a light and waking the household) cannot be turned on without changing the temperature setting. You have to press a button to turn on the backlight, and anybutton you press (even once) will either change the display to something other than the set temperature, or change the temperature setting itself. Of couorse, you can set it back where you want it, but it would be nice if there was a way to just turn the backlight on. Other than that, no complaints.
I recently installed this t-stat and recommend it. However, there are a few things you need to know upfront to make the installation process a little smoother.I had a direct swap with a manual Honeywell t-stat, so the wiring was easy and even the previously drilled holes worked. I envision that it was the easiest installation possible, yet it took me 45 minutes to get it done ... when programming time is included. I have a gas furnace with A/C, and I'm guessing things like heat pumps, multi-stage units, etc. can be trickier. So don't bank on the "15 minute installation" that you read on the packaging. That might be true for Honeywell engineers and HVAC technicians, but not if you're doing this for the first time.Secondly, read through all of the installation and programming instructions first, including the advanced section, even if you don't think you'll need it. That allows you to get the limited tools together you'll need. Also the advanced section shows you how to change some settings that are referenced in the basic set-up section ... but don't appear on your t-stat until they are activated by you - using the advanced section.dogfood
I purchased two of these to run the 2 separate heating and cooling systems in my home. Both were identical in quality and operation and their temperature measurements matched when sitting side-by-side.I'll be honest, there are three things I really don't like about this thermostat. The first is that it makes a clicking noise every time the A/C comes on (probably when the heat comes on too). Second, the quality of the screen isn't all that great. When the light's on you can see some discoloration on the left side. Third, it seems flimsy -- qualitative but telling. It just feels like it could break when I put it on/take it off the wall (something I'll only do a few times in it's lifetime, mind you).That being said, I gave it 4 stars because I felt it was a great value for the price. Removing the old thermostats and installing the new ones took less than 15 minutes each after a 5-minute call to customer service. If you're the least bit mechanically-inclined it should be a breeze. The only challenging task I had was making a jumper to connect two terminals, but again, not that bad.The programming is pretty straight-forward and clear. The users manual provides good instructions on everything you'll need to know to get it working the way you'd like.I can't comment yet on efficiency -- I know it's saving me money but I'm not sure how much.
I originally wanted this thermostat but started with the 6400 series because my wife was freezing in the cold weather and our old thermostat was broken.I installed the 6400 first, and got it at Home Depot at the same price Amazon was offering for the 7500. I would have paid $100 for the 7500 there, but they were out of them.I ordered this one after I installed the 6400 because I wanted the 7 day programmability, the furnace filter reminder, and I was hoping not to need batteries, but I have a two wire system, so there is no voltage available when the thermostat calls for heat. Thus, I need to have batteries in it.The furnace wires were pre-tagged, so I didn't need the tags. They included mounting screws and dry wall anchors, but there's a stud behind the thermostat so I didn't need the anchors.The way to get into the advanced menu is wrong in the instructions. They call for hitting another button, then holding the fan button down for 5 seconds. Other posters say just holding the fan button for 5 seconds is the way to go. I have it programmed for my system (heat only) so there's no reason to revisit it unless we change to a different type of system (furnace plus A/C, or heat pump, etc.) I like the 6400's advanced settings entry better.I trusted the temperature read out in this thermostat, but my wife didn't so she put a thermometer on top of it, and finally admitted it was correct. For whatever reason, her bathroom is a couple degrees warmer than the hall, even though the bathroom opens onto the hall.My thermostat's back light comes on as soon as push a button, but the function the button controls has a delay in it, so pushing a button to turn on the light doesn't change anything. I prefer to hit the schedule button because it might take me to the schedule page, but you have to work at it to change any schedule settings.I thought it was worth $69 when I bought it, and now its come down $15.00. Wish I could have waited.The furnace seems to run less now than with my now broken (pre-Honeywell thermostat). About the time I notice the furnace is on, it turns off.
