I Tested And Reviewed 7 Best Thermostat For 2 Story House (2023)

I recently purchased this thermostat as an upgrade from a previous model that did not have a back-light. One of the main reasons for my purchase was the need for a back-light, as I found it inconvenient to always have to turn on the room light at night to make adjustments. This thermostat solves that problem perfectly, as it has a back-light that only comes on when one of the setting controls is pressed. The back-light is not too bright and automatically turns off after a few seconds, saving battery life.

Contrary to some reports, I did not experience any difficulty in removing or putting back the cover. The metal connector pins in the cover fit perfectly into the corresponding slots in the base, ensuring a secure closure. Removing the cover is necessary for attaching the base to the wall and connecting the wires from the furnace, but it actually makes the installation process easier. It is worth noting that a small and specific screwdriver size is required to secure the wires in their posts.

While this thermostat is not programmable, meaning you cannot set it to change temperatures at specific times of the day, it is compatible with a wide range of heating, cooling, and fan units. The instructions provided are detailed and easy to follow, making it possible to hook up this thermostat to almost any home HVAC system. Additionally, there is a technical section for installers to make advanced adjustments for more complex systems.

The display alternates between showing the current room temperature and humidity, which may be overwhelming for some users. However, I did not notice if there is a way to stop this feature. The installation of the 2 AA batteries is straightforward, and the display will notify you when the batteries are running low.

In the accompanying pictures, the numerals may not be visible due to an issue with the camera lens. However, the back-light is bright and functions as described.

I recently purchased a new thermostat to replace my old, unreliable one, and I am extremely satisfied with my choice. The installation process was surprisingly easy, thanks to the helpful youtube videos I found. The thermostat even came with labels, making it easier for me to upgrade or replace it in the future.

Once installed, the thermostat looked great. The display was illuminated, allowing me to see it clearly at night without being too bright. All the buttons were responsive and worked as expected. I was pleasantly surprised by the high quality of this thermostat, especially considering its affordable price.

I actually bought this thermostat as a gift for my boyfriend's grandmother. I initially visited Home Depot but found their options to be expensive and not suitable for her needs. After searching through various options on Amazon, I chose this one because of its large numbers and user-friendly buttons for temperature adjustment. The display was easy to read, even for someone with impaired vision. Additionally, the installation process was a breeze, which is always a plus. I would definitely rate this thermostat a 10/10.

In contrast, my previous programmable thermostat from Honeywell was a constant source of frustration. The display was poorly designed, with a dull green background and black LCD characters. To make matters worse, the display was only partially illuminated by a small penlight bulb, making it difficult to see. We had to shine a flashlight on the display just to read it properly.

However, the new thermostat I purchased seems to be doing the job well. I labeled each wire before disconnecting them and easily connected them to the new thermostat. After inserting the batteries and turning the circuit breaker back on, the thermostat started working flawlessly.

There were a few minor negatives I encountered during the installation process. Firstly, there were no instructions on how to remove the backplate from the faceplate when it first came out of the box. It took some trial and error, but I eventually figured it out. Secondly, I accidentally fumbled with the battery door opening, as there were no clear indications on how to open it. However, once I overcame these initial challenges, everything else went smoothly.

One thing to note is that this thermostat does not have a setback function, but that was not a dealbreaker for me as I was aware of this limitation when purchasing it. Personally, I rarely used the setback feature on my previous thermostat, so I didn't find it to be a major drawback. The main advantage of this thermostat is its ability to display the settings and readings clearly, making it ideal for those with poor eyesight.

I recently purchased this thermostat to replace my old one that stopped working. I was pleasantly surprised by the impressive display of this thermostat. The numbers are large and bright, making it easy to read the temperature in the room and the temperature that I have set. The arrow keys are also large and easy to use. Additionally, the display lights up when you touch the arrows, which is great for when the room is dark.

One feature that I particularly appreciate is the easily accessible battery compartment. Unlike other leading brands where you have to pry the unit apart, this thermostat has a simple flip open cover that allows for easy changing and replacement of batteries. This also allows me to write the date of battery installation on a piece of tape, giving me peace of mind about how long they have been there.

I have been using this thermostat for about two years now and I am highly satisfied with its performance. The display is energy efficient and the thermostat is easy to operate with just a click of a button to adjust the temperature.

Furthermore, the installation process was easy and the instructions provided were informative and easy to understand. The thermostat even came with installation screws, which was a nice bonus.

The Honeywell C30 thermostat is an attractive and well-made device that is suitable for controlling propane furnaces. However, some users have reported issues with the thermostat tripping, which did not occur with their previous thermostat. The diagram in the instructions for setting the adjustment lever may be difficult to decipher, but a PDF manual with colored diagrams can be easily found by searching for "Honeywell C30 manual."

In addition, there have been instances where users have been unable to control an old floor gas heater with only two wires. Despite numerous experiments, the gas heater could only be reliably turned on and off by attaching/detaching the two wires to a AAA battery. It seems that the old gas heater requires a small current to activate, which this thermostat does not provide. Even other Honeywell thermostats that use batteries have also been ineffective in these cases. Further guidance is needed in such situations.

For users who are not experienced with thermostat installation, the Honeywell C30 is a straightforward swap for an existing thermostat. With just two wires and a couple of screws, it can be installed in as little as 10 minutes and effectively control a Williams gas heater from the 70s.

This thermostat is particularly suitable for those who have older two-wire thermostats and do not have a Common wire. It functions similarly to these older thermostats and is a great choice for an upgrade, especially if the old thermostat contains Mercury. The Honeywell C30 is mercury-free, making it a safer option in terms of disposal when it eventually needs to be replaced. The product also comes with a wall plate for easy installation, but can also be mounted using adhesive if preferred.

Another use case for this thermostat is for controlling gas fireplaces. Users have found it easy to install and have reported that it works perfectly. It is a cost-effective option for those who require a basic thermostat without the need for advanced features. Furthermore, the absence of mercury in this thermostat ensures hassle-free disposal when the time comes for a replacement.

I recently purchased a second thermostat to replace some older Honeywell models that I had installed seven years ago. I must say, the new thermostats are a significant improvement in terms of installation and setup. It took me less than 5 minutes to install the thermostat, and the only slightly challenging part was getting the wires into the jumper blocks. I would recommend using a small jeweler type flat head screwdriver for this task.

One thing to note is that during installation, holding the thermostat can cause the display temperature to increase slightly, as your hand heats up the device. However, this issue resolves itself within 5-10 minutes as the thermostat adjusts to the ambient temperature.

I found a helpful tip from another reviewer who suggested opening the thermostat from each corner to install the batteries. This method worked perfectly, as the cover can be quite tight if you try to open it from the middle using the finger indent.

Programming the thermostat was incredibly easy. You simply set your desired wake, leave, return, and sleep times/temperatures for both weekdays and weekends, as well as for heating and cooling. The "hold" and "run" buttons are self-explanatory and make it easy to override the programmed settings when needed.

One minor issue that has been noted by other reviewers is a smudge at the lower right of the display. While it may not be aesthetically pleasing, I personally believe that the functionality of the thermostat is more important than its appearance. Therefore, I can live with this minor flaw.

I will update if any issues arise, but so far, straight out of the box, these thermostats have proven to be better than the "professional" models I initially purchased. Additionally, I was able to take advantage of an energy rebate program in my state, which offers rebates of up to $25 for 5-2 programmable thermostats. So, in the end, these thermostats have cost me nothing!

If you are replacing an old unit, I highly recommend taking a picture of the wiring setup before removing it. This is important because the colored wires on older units may be different from those on the new ones. However, the terminals on the new thermostat are labeled, making it easy to replace the wires in the same configuration as the old unit. The only issue I encountered was that the new thermostat was smaller than the old one, resulting in a different-colored wall behind it. To address this, I placed the rear housing from the old thermostat between the new thermostat and the wall, which didn't look too bad (see attached photo). This solution was much easier than repainting the walls or trying to match the paint for a small area.

The Honeywell T5 thermostat is a great choice for those looking for a programmable thermostat without the need for bells and whistles like WiFi connectivity. It offers the necessary programming features and even has a "recirculate" mode for the fan, which helps evenly distribute the temperature from room to room.

Installation of the thermostat was easy, thanks to clear and detailed instructions provided. While the included drywall anchors may work in most situations, some users may prefer to upgrade them for added stability. However, this is a personal choice and not a fault of the unit itself.

Programming the thermostat was also straightforward, although having the installation book handy to reference the settings is recommended. Once you get the hang of it, setting up the thermostat becomes a breeze. Some users have complained about having to remove the unit from its mount to replace batteries, but this is a standard practice for most thermostats. If you prefer a battery-free option, make sure you have a "C" wire and consider choosing a different thermostat.

One issue that some users have noticed is that the displayed ambient temperature on the Honeywell T5 may differ slightly from their previous thermostat. However, this could be due to the accuracy of the old unit or the new Honeywell thermostat. Unfortunately, Honeywell does not provide an offset adjustment for this discrepancy. However, users can easily compensate for the difference by programming the thermostat accordingly, ensuring the house remains comfortable.

The Coleman thermostat I purchased was a great replacement for my old analog thermostat. The large numbers on the display make it easy to read, and the installation was a breeze with just two wires. I connected the white wire to the W terminal and the red wire to the RH terminal. It doesn't get any better than this! The quality of the thermostat is also excellent.

I specifically chose this thermostat because I didn't want to deal with programming. I just wanted basic functions like cooling, heating, temperature adjustment, and on/off control. This thermostat fulfills all those requirements and works well.

The value for money with this thermostat is outstanding. It is easy to install with the right tools, and I appreciate the non-programmable feature. The only downside is that you have to remove the cover to switch between "electric" and "gas" during the fall/winter season. However, overall, the quality and installation instructions are great.

I am impressed with the appearance of this thermostat considering its price. It has all the features I was looking for, even those found in higher-priced models. The performance is excellent, and it looks well-made. I'm so satisfied with it that I plan on buying a second one to replace our first-floor thermostat.

Having installed many thermostats for myself and my family members, I can confidently say that this unit is the simplest and easiest to use. The battery replacement is also straightforward, and I appreciate the easy access to it. The humidity percentage feature is another great addition, and it is accurate. I have checked it against my TeccPo dehumidifier, and the readings match. This is an excellent and affordable product.
