The wire terminals are clearly labeled and sturdy, ensuring tight connections and compatibility with Rheem electric heat pumps. Installation is a breeze, with no problems reported and it worked seamlessly from the first use.

Many customers have praised this thermostat for its simplicity and ease of use. It has been purchased for multiple rental properties with heat pumps, and tenants have found it easy to figure out without any complicated programming.

In comparison to more expensive thermostats, such as the "big name" brand, this thermostat stands out. It is a fraction of the cost and offers large letters and numbers, making it readable even for those with poor eyesight. The physical buttons for Heat and Cool, along with the old-school switches, provide a familiar and user-friendly experience.

Even in mild Southern California weather, this thermostat performs admirably. Its large and legible display, along with easy setup and helpful labels, make it pain-free to switch out from an old unit. The buttons and switches are satisfying to operate, especially the large up and down arrows for temperature adjustment.

I recently purchased this thermostat and I have to say it offers great value for the price. The instructions that come with it are clear and even include examples of different wiring options, which was very helpful for me. I have an older heat pump system with single stage cooling and dual heating with 7 wires, and this thermostat was able to handle it without any issues.

One tip I would recommend is taking a picture of your original wiring before removing your old thermostat. This will help aid in the installation process. One of the great features of this thermostat is that it gives you the option of using 24v or batteries or both to power it. I chose to use both because my wiring has the 24v common wire that's needed to power the thermostat. This ensures that there is no memory loss if the power turns off.

Programming the thermostat was easy and it offers a lot of useful features that allow you to customize and fine-tune it as needed. I couldn't be happier with this purchase and would rate it A+++++++. It has definitely exceeded my expectations.

I initially needed a quick and inexpensive thermostat to test my recently-repaired heat pump system, as I suspected my old thermostats were faulty. Most basic thermostats at this price range are not typically configured to operate heat pumps. However, this thermostat is specifically designed to do so and controls 2-stage heating and 1-stage cooling with or without auxiliary or emergency heat. The price of just $31.99 (USD) plus tax was a great deal.

One thing I would have liked to see in this thermostat is automatic switching between heating and cooling. It currently requires manual switching, which is a minor inconvenience. The thermostat can be powered by the 24V transformer (requires a common (C) wire), batteries only, or both, with the batteries acting as a backup power source. The batteries are easily accessible behind a swing-down panel in the front.

The thermostat is programmable with options for 5,1,1 (weekdays, Saturday, Sunday) or none (hold). It also has a backlit display, although there is no always-on option. Some other features include a filter change reminder, temperature offset, compressor 5-minute lockout, and more.

While installing the thermostat was quick and easy, separating the unit from its wall plate proved to be a bit difficult. I had to use a butter knife to carefully pry it apart. Additionally, the supplied drywall anchors are weak compared to the force required to separate the two halves. I ended up pulling the whole unit out along with the screws and drywall anchors on one side. I replaced the anchor and everything was fine.

I recently purchased and installed a heat pump with aux heat, and I am extremely satisfied with my choice. After conducting thorough research, I decided to go with this particular model due to its reputation for being easy to install, and it did not disappoint. It took me approximately 15 minutes to complete the installation process, as I made sure to carefully note down which wires needed to be connected where. To my delight, the wire connections on the new thermostat perfectly matched my previous one. This seamless installation process left me feeling very content. I am hopeful that this new heat pump will have a long lifespan, potentially even surpassing the 18 years of my previous one.

The setup and wiring of this thermostat were also incredibly straightforward. It took me a total of 20 minutes, including a minor setback when I stripped a screw during mounting. However, once I overcame this hurdle, it took me less than 2 minutes to complete the wiring. It's worth noting that I am not an electrician, yet found the process to be quite manageable. After turning the thermostat on, I navigated through the menu to set the time and temperature programs, and just like that, I was done. Another fantastic feature is the common wire, which allows for a permanent backlight if desired, adding a nice touch to the overall user experience.

My previous thermostat was a Honeywell, and I had issues with the lack of turn on or off adjustment. The AC would constantly cycle on and off, disrupting my day and night. The factory settings on the Honeywell were simply too close together, resulting in frequent interruptions. However, this new thermostat offers various sensitivities that can be adjusted. As a result, my AC now runs when it needs to and stays off for a reasonable duration when it is not required. This improved control over the cooling system has made a significant difference, and I believe this thermostat is well worth the investment.

In addition to the easy installation and setup, the programming and temperature control features are also user-friendly. We have a Goodman 14 Seer 3 ton heat pump unit, and the wiring connections on the Emerson unit were identical to our previous thermostat. This made the transition from our old unit to the Emerson unit incredibly smooth and hassle-free. It took us less than ten minutes to remove the old unit, transfer the thermostat wires, and program the new one. This was a refreshing change compared to our previous TESP unit, which took us over 2 hours to program due to its complexity. I highly recommend this Emerson thermostat to all DIY homeowners, as it not only saves money but also offers a simplified and efficient user experience.

I recently replaced my antique thermostat with this Emerson unit, and I must say, the upgrade has been excellent. Thankfully, the color coding of the wires on the new thermostat matched my previous one, making the installation process much easier. With this new thermostat, I now have precise control over my heating and cooling systems, allowing for more accurate temperature regulation. Additionally, I can now implement setbacks for nighttime operation, further enhancing energy efficiency. I do want to clarify that while some may claim to have installed this thermostat in minutes, I found that it does take a bit longer to properly install it on the wall, connect the wires, run tests, and configure all the functions to meet your specific needs. However, the time invested is well worth it for the improved functionality and convenience this thermostat offers.

I recently purchased the Honeywell T6 Pro thermostat and I have mixed feelings about it. Firstly, I must mention that the listing on Amazon does not accurately represent the product. The thermostat appears to be a basic and outdated model, and the multicolored handheld remote shown in the listing is not included. It is possible that Amazon made an error in the listing and it may be corrected by the time you read this review.

I decided to purchase the Honeywell T6 Pro after my previous thermostat, the Honeywell Lyric Round, stopped working just one month after the warranty period ended. The Lyric Round had another major flaw that disappointed me, which I will discuss shortly. I opted to try the Schneider Wiser smart thermostat as a replacement for the Lyric Round. However, I experienced issues with the Schneider Wiser, as it failed to accurately indicate the temperature in my home on multiple occasions. This resulted in my home becoming extremely cold, and had I been away for a longer period, it could have caused damage to my pipes or even harm my cat.

One of the features I liked about the Honeywell Lyric Round was the geofence functionality, which the Schneider Wiser lacked. Although it is possible to download a generic app for Android that provides some form of geofencing with the Schneider Wiser, it is not officially supported by Schneider. Given the potential risks of freezing pipes or endangering my cat, I decided to return the Schneider Wiser and look for an alternative.

Ultimately, I ended up purchasing the Honeywell Lyric T6 wireless thermostat, which is compatible with the Honeywell Home app that I had previously enjoyed. The Lyric T6 does not have the same flaw as the Lyric Round when using a lithium battery without a C wire, as it does not offer the option to use a battery at all. I replaced the battery in the Lyric T6 after a year without any issues, as it did not die or indicate weakness.

One major issue I had with the Honeywell Lyric Round was its notification system. The thermostat would only send a "notice" to your phone when the battery was dying, which often got buried among numerous other notifications. On the other hand, the thermostat would send an "alert" for humidity dropping below 31, which was impossible to miss. I found this design flaw to be frustrating and illogical.

By using a C wire with the Lyric T6, the battery is eliminated, along with the major flaw associated with the Lyric Round's lithium battery option. Both the Lyric T6 and Schneider Wiser come with a C wire adapter, so I decided to give Honeywell another chance.

With the Honeywell Lyric T6, I now have the peace of mind to leave my home for extended periods, such as a week-long trip to Vegas during winter. I can rely on the Honeywell Home app to monitor the temperature and ensure my cat is safe. I would not have the same confidence in the Schneider Wiser after the issues I faced.

While the thermostat does not offer advanced features such as controlling other appliances or providing weather updates, it excels at its primary function of maintaining the desired temperature in your home. It is a reliable and straightforward thermostat that gets the job done without causing any frustration.

In terms of performance, the Saswell thermostat has received positive feedback from users. It effectively replaced malfunctioning thermostats and works well with Trane heat pump packaged units. However, it is worth noting that some users have mentioned the need to adjust the thermostat from fast cycles to slow cycles to prevent frequent on and off cycling. The instruction book provides clear instructions on how to make this adjustment.

One minor drawback of the Saswell thermostat is that the display can be difficult to read if the thermostat is installed above eye level. However, considering its affordability and simplicity, this can be easily overlooked.

I recently purchased the T21STK-0 thermostat and overall, I am quite satisfied with its performance. The unit has lived up to its advertised features and functions efficiently.

One aspect that I found slightly confusing initially was the wiring instructions. However, as a homeowner, I was able to figure it out fairly easily. Despite this minor hurdle, the thermostat has operated seamlessly and is user-friendly. The settings are straightforward and once programmed, there are no worries or complications.

The display of the thermostat is large and easy to read. It conveniently shows both the current and set point temperatures simultaneously, allowing for quick and accurate adjustments. The installation process was hassle-free, and the printed manual included in the package was thorough and well-written in decent English.

In terms of performance, the thermostat operates as expected, especially when the cycle rate is set to "slow." The ability to adjust the variables and customize the settings is a great feature. It should be noted that the maximum degree adjustment is 1.5, which may be a limitation for some users. Additionally, the thermostat functions well on batteries, although the longevity is uncertain.

On the positive side, the price of the T21STK-0 thermostat is fair, making it a worthwhile investment. However, there are a few cons to consider. Firstly, the manual is not available online or anywhere else, which could be inconvenient for those who prefer digital access. Secondly, the inside of the drop-down cover lacks a configuration instruction sticker, which would have been helpful for quick reference.

Furthermore, the product image shows a red Saswell logo, but the unit received had a grey logo. While this doesn't affect the thermostat's performance, it may be misleading for potential buyers. Lastly, the unknown factor of battery longevity raises some questions. However, based on customer reviews, the alkaline batteries have lasted around 16 months, which is commendable.

To ensure a smooth purchase, it is crucial to order the correct product based on your specific needs. It is essential to determine whether you require a stage one or stage two thermostat, depending on your emergency heat requirements.
