The screen is color adjustable, meaning you can choose a color palette that suits your décor. The text and display is an easily readable white font.

Professional installation is recommended with this thermostat, as it requires a C-wire to provide constant power. If you’re upgrading your thermostat, and your old model didn’t have one, then you’ll need to have one installed. It is possible to use the fan-only wire as the C-wire, but then you lose your ability to just have the fan running to circulate the air.

Key Features:

  • 7-day programming with multiple intervals
  • Thermostat adjustable via Total Connect Comfort App
  • Requires C-Wire connectivity
  • Compatible with Amazon Alexa, Google Assistant, Samsung SmartThings, and IFTTT

Best Honeywell Thermostat Reviews This is one of the more simple thermostats that Honeywell offers, but that doesn’t mean it isn’t lacking in features. After all, sometimes you don’t need all the bells and whistles of Wi-Fi or voice assistant connectivity. You just want a reliable thermostat that works. And that’s where this model delivers in spades. It features a 5-2 programming cycle, with four adjustable intervals, so if you have a set schedule with little deviation, this is perfect.

Additionally, it doesn’t require a C-wire for power; all you need are 2 AAA batteries to keep this thermostat running. Battery life averages at one year with normal use, so you don’t have to worry about coming home to a house that’s 90 degrees in the summer (unless you like it that way).

Another feature that makes this an outstanding model is that it is fully compatible with electric baseboard heat, something that some of the other thermostats can’t do. This is perfect for a rental unit or upgrading a finished basement; anyplace where you want a little more, but don’t want to go with all the bells and whistles.

  • Unit measures 4-7/8” x 3-3/8”

Honeywell RTH9585WF1004 Wi-Fi Enabled Programmable Color Touchscreen Thermostat

Best Honeywell Thermostat Reviews This is one of the best smart Honeywell thermostats available on the market today. And when they say that this is a smart thermostat, they mean it. It learns and recognizes your programmed heating and cooling cycles and how you deviate from them. As it learns, it begins to self-adjust so that you no longer have to.

Let’s say that you have it set for a common workday cycle, where you raise the thermostat to 80 degrees when you leave in the mornings and lower it to 76 a half-hour before you come home. But every Thursday, you have a work meeting and come home an hour early. So on your way home every Thursday, you use the app to lower the temperature so that it’s comfortable when you get home.

After a few weeks of this, this thermostat will recognize this pattern and change the temperature an hour early on Thursdays without you having to log in. This saves you time and distractions, knowing that your home is ready when you are. Another amazing feature of this thermostat is that the display gives you at-a-glance information.

This can range from a daily forecast to the relative indoor and outdoor temperature and humidity so you can dress and adjust accordingly. The display will also show you when it’s time to change your HVAC filters and let you know if the temperature outside goes below or exceeds a set threshold.

Key Features:

  • Multiple programming options for peak savings
  • Wi-Fi connectivity
  • The touch screen has multiple colors available with local weather displayed
  • Compatible with Amazon Alexa, Google Assistant, Samsung SmartThings, and IFTTT.

Honeywell Thermostat Buying Guide

Best Honeywell Thermostat ReviewsSection One: understanding how your HVAC system and thermostat work together

In general, there are three types of heating systems that are most common on the market. They are the single-stage HVAC, the dual-stage HVAC, and the multi-stage HVAC.

Essentially, the single-stage HVAC works at one of two speeds; it is either on or off. This is the most common type of HVAC system. When the thermostat detects that the temperature in your home or the zone has gone above or below the desired temperature, it turns on full blast. It then runs until the thermostat detects that the temperature has returned to the desired setting and then the HVAC system shuts off. This repeats and cycles throughout the week.

The two-stage HVAC system has three settings. It is either at 100%, at 65%, or off. Normally this system, when adjusting to normal fluctuations in temperature, will run at 65% power to perform immediate corrections. If however, the thermostat detects a big variance, such as you coming home and lowering the temperature on a scorching summer day, it will run the HVAC system at 100% for a cycle. This is so the temperature is brought to the desired setting quickly. At this point, the system goes back to normal and will you 65% power to adjust for normal fluctuations.

Multi-stage HVAC systems often use two or more stages, and they can be different for both the heating and cooling. For example, you may have a 3-heat/2-cool HVAC system, meaning that the heating runs in three stages (often 40, 65, and 100 percent) and the cooling runs on two stages (65 and 100 percent). Some systems go up to four stages because as you increase the number of stages, you also increase the efficiency.

Some newer HVAC units have completely variable controls, meaning that a computer decides what the optimum run speed for the HVAC system is depending on the climate variables. This variability in HVAC means that it is important that you know what type of HVAC system you have because not all thermostats are compatible with all HVAC systems.

When in doubt, make sure to refer to your HVAC documentation for more information.

Section Two: Asking the Right Questions

Best Honeywell Thermostat ReviewsNow that you know what type of HVAC system you have, you should think about how compatible a thermostat will be with your existing heating and cooling. You might also think about how important a smart system is for you based on your schedule. Finally, installation and cost are the other two important factors in choosing a thermostat.

What Kind of HVAC System do you have?

This question goes beyond a single or multistage HVAC system. For example, there are milli-volt systems that operate gas-powered wall heaters. Other systems are baseboard electric heaters, which many thermostats are not compatible with.

Other HVAC options are heat pumps that have a backup heating source, such as an electric supplement. Some systems in certain climates are only built for heating and don’t have an air conditioning or cooling system built-in. Many older apartments in the Pacific Northwest are like this because of the traditionally mild climate of the area.

You also need to know if your HVAC system is a multizone unit. That is if it heats and cools different parts of your home separately. If it does, you need to know that your thermostat can handle those zones easily. Knowing what type of HVAC system you have is vital to getting a thermostat that will work properly with it.

Smart Thermostat or No?

For some people, the thought of their smart thermostat learning their movements and routines is something out of a science fiction movie. Whether that’s a good thing, like Star Trek, or a bad thing like SkyNet is up to you. But this feature is one that is becoming increasingly popular in today’s thermostat market.

Essentially a Honeywell smart thermostat begins to learn when you go outside of the programs that you’ve set. Most thermostats have either a 7-day setting, where you can set each individual day or a 5-2 setting. The 5-2 is two settings; one lasts for five days, and the other for two. Essentially these mark the weekend and the workweek.

If you change from these programmed settings, the thermostat uses an algorithm to keep track of them and gradually changes the programs to adjust to what your actual movements are. The ways it can learn are from using geofencing, where it tracks your phone, or from your manual input and changes to the wall unit or by an app.

If you have a constantly changing schedule, you might want to invest in a smart thermostat. It could be that the thermostat will gradually find patterns in your schedule that you can’t see. However, if you have a consistent 9-5, Monday through Friday schedule, consider leaving the smart option on the table. You can also read about the popular Nest thermostats here if you are looking for more options to choose from.

What About Installation?

Best Honeywell Thermostat ReviewsMost modern thermostats require a constant source of power, and that means having a specific set of wiring. The wire that provides the power is commonly called the C-Wire. This enables your thermostat to run without having to rely on batteries or having an external power adaptor.

If you are upgrading from one modern thermostat to another, then it’s likely that you already have a C-wire installed. In this case, installation is something that you should be able to handle, as long as you’re comfortable working with electrical wiring. If you don’t have a C-wire and don’t feel like installing one, you can take a shortcut.

Some people will use the G-wire as a substitute, but the G-wire is the control for fan-only mode. So if you do this, you will lose the ability to just turn on the fan and have periodic circulation through your home.

One thing to note, however; if your old thermostat is not one that required a C-wire, or you aren’t comfortable with working with electrical wiring, then professional installation is the way to go. Of course, this does tack on an additional cost, which ties in with our last question.

How Much Are You Willing to Spend?

This is probably the most important question for many people. Cost is king, after all. But with thermostats, as with so many other things, you get what you pay for. Multiple features will bump up the cost, such as Wi-Fi connectivity and smart device integration. But these same features give you convenience and time savings that might be worth the added expense.

Another feature that adds expense is smart learning. This may seem frivolous at first glance, but spending an additional twenty or thirty dollars on a unit that can save you hundreds over the years is a sound investment.
You should also consider where you are placing these thermostats. If you’re putting them in rental units or in-law quarters, you might not want to spend the money of a full-featured unit that your tenants won’t understand or want to use.

And as always, when considering the initial cost of the unit, you should always factor in the cost of professional installation. In some cases, failure to have the thermostat professionally installed can void the warranty on your HVAC system.

Section Three: Awesome Features

Best Honeywell Thermostat ReviewsThermostats have started to come with all sorts of amazing features designed to save you money and help you reduce your carbon footprint. Here are a few of the neater features that you can look for when shopping for your next Honeywell thermostat.

Geofencing – This is a way for your thermostat to self-adjust based on whether you are home or not. Essentially, it uses your phone, which is connected to your thermostat. When your phone detects you are a set distance away from home, it tells your thermostat, which then goes into its Away mode.

This range is variable, often anywhere from 500 feet to 7 miles. That way, as soon as your phone detects you’re back within range, it automatically returns to your home setting, and you arrive home to a comfortable house.
This feature is best for single people or couples, but not for large families. If multiple people are coming and going, this could create quite the snafu for your thermostat.

IFTTT – This feature stands for “If This, Then That.” This enables you to set up a series of conditions for your thermostat that ties it in with other smart devices in your home. For example, you can set up an IFTTT rule that says if you turn off a light in a room, then the thermostat that controls that zone will go into away mode.

The ability to create chains of conditions (called applets) is only limited by your imagination. If you have a smart oven, and you’re baking, you can create an applet that turns the AC up based on how long you’re baking.
This is a system that can be a little overwhelming to some, but for others, it’s a chance to create a truly smart home that is connected with everything they do in their lives.

Conclusion

No matter what type or how big of a home you have, controlling the interior climate is important. Being able to do it while saving yourself money and reducing your carbon footprint is just icing on the proverbial cake. This buying guide should hopefully guide you through some of the thought processes of buying and upgrading your thermostat while providing you with a starting point. Happy shopping!
