MRCOOL DIY Multi-Zone 5th Gen 55K BTU Five Zone Ductless Mini Split with Ceiling Cassettes 6K + 6K + 12K + 12K + 12K – A Heating and AC System You Can Install By Yourself!

MRCOOL DIY Series Ceiling Cassettes provide efficient heating and cooling while remaining out of sight and discreet, making them a perfect fit for any space. The cassette features an easy, low-profile installation and can be recessed between all types of joists on 16 inch centers, including pre-manufactured I-joists. This makes it a perfect option for both new construction or retrofits. It doesn’t have strict installation requirements like other ceiling cassettes, so you’re able to install it in the location that suits you best, without using ductwork or wall space. The cassette works with the MrCool® DIY® Quick Connect® line set and the No-Vac® Coupler to increase the length of the line set. Not only does the unit offer quiet operation and multiple operating modes, but it also features the Elevation function that lowers the filter panel for easy air filter maintenance. Purchases of the MrCool® DIY® Series Ceiling Cassettes are protected by a limited lifetime warranty in addition to a 7-year compressor warranty and 5-year parts warranty.

The MRCOOL DIY 5th Gen Multi-Zone 55,000 BTU 22 SEER2 5 Zone Ductless Mini Split System - 6K + 6K + 12K + 12K + 12K is ideal for homeowners looking to efficiently cool and heat five rooms of varying sizes. This system combines high performance and flexibility with DIY-friendly installation, so you can skip the HVAC crew and save thousands on labor. Everything is powered by a robust 55K BTU condenser, backed by a 7 Year Compressor Warranty (with optional lifetime coverage) and a 5 Year Parts Warranty.

MRCOOL DIY 5th Gen Multizone 55,000 BTU systems can support up to five indoor units—the maximum supported for this condenser.

Feel free to mix ceiling cassette air handlers and wall mounted air handlers together in a system by visiting Building Your Own Custom Mini Split System.

The MRCOOL DIY 5th Gen 5-Zone 55,000 BTU 22 SEER2 (6K + 6K + 12K + 12K + 12K) Ductless Mini Split System with Ceiling Cassette units are super easy to install and require no special training or expensive specialty tools. The DIY system includes Quick Connect lines that are pre-charged with eco-friendly R-454B refrigerant. Due to the Quick Connect line set, you don’t have to hire an HVAC technician to complete the install. We also have simple video instructions on how to install a DIY Multi-Zone unit yourself!

The MRCOOL DIY Multi-Zone 55,000 BTU 22 SEER2 5 Zone Ductless Mini Split System - 6K + 6K + 12K + 12K + 12K can cool through the Summer, heat through the Winter, and dehumidify through the wet seasons. Plus, you can quickly check the temperature of each room in your home from the easy-to-read digital display or from the MRCOOL Smart Controller mobile app. The display on the front of each indoor air handler unit can also display troubleshooting codes and alerts, so you are always aware of any issues with your system. Operate each unit wirelessly with either the included remote or with the MRCOOL Smart Controller app for Apple or Android devices. You also have the ability to control your mini-split unit with Amazon Alexa or Google Home.

The five MRCOOL DIY Multi-Zone air handlers included in this set provide directional control of the heated or cooled air. This distributes the air evenly so everyone in the room can stay comfortable. If you are in a situation that requires forced cooling, you can set your MRCOOL DIY System to manual with the button located on the right side of the unit under the front panel. In this emergency operation mode, you can test the cooling operation of your unit after installation or to complete a maintenance task.

In auto mode, each unit provides air for your home at your desired comfort level. Set your desired temperature, and the HVAC unit will determine how much heat or air conditioning is needed. You can also set this system to a drying function, which will continue to control the space’s air temperature while dehumidifying.

Use the sleep mode at night to save money on your utilities bills and use less energy. Sleep mode operates in an 8 hour window once turned on.

The MRCOOL DIY Multi-Zone 55,000 BTU 22 SEER2 Five-Zone Ductless Mini Split Air Conditioner System - 6K + 6K + 12K + 12K + 12K comes with many options, so you can customize your system based on your needs. Limit your energy usage and save money on your utility bill by using the system’s timer function. If your system begins to run low on refrigerant, an alert will appear on the easy-to-read display on the front of each air handler, letting you know there may be a leak. If you desire to keep a room quiet and minimize lighted alerts, you can mute each indoor unit. By muting the system, the buzzer for alerts will not sound and the LED lit display will turn off. Should the unfortunate event of a power outage occur, the MrCool system will automatically shut off and then back on with the same settings once power returns.

Easily maintain your MRCOOL DIY Multi-Zone 55,000 BTU 22 SEER2 Five-Zone Ductless Mini Split Air Conditioner Unit with alerts and reminders. Any troubleshooting codes will appear on the front display and the user manual contains an index for common codes. Air filter cleaning alerts are automatic, and you can easily keep the minimal indoor units clean with a dry or damp cloth.

Lightweight, Options, and Ease of Use Make this a Great Watch
Color: Black
I have purchased many Timex watches over the years and I am entirely satisfied with this watch. I always buy the sports watch, as I swim and do triathlons. Things I like about the watch: *Setting the watch is easy and the instructions are clear (although the printed instructions are very small!) * The watch is not too big. So many watches have too many features and they are large, bulky, and heavy. This watch is sleek, has a low profile, and has a size that is ideal for average needs. * The numbers are big enough to see easily at a glance. * There are enough useful options, and this watch is not overloaded with too many options. Too many options are confusing to me. I like the simplicity of this watch and the ease of use of the options it has. * I like the plastic watch band. I have tried the velcro strap bands and they wear out after a year or so of use. The plastic band will eventually break, but is fairly easy to replace. * I like the price. At less than 35 dollars I have everything I need in a watch. * I like and use frequently the Indiglo feature. I have even used Indiglo to find my way to the bathroom at night from bed! The light on the dial is bright enough to make your way through the dark for a short trip! Things I don't like: There is not much I don't like about this Timex watch. I suppose my biggest complaint about this watch and any Timex watch is the difficulty in changing the battery. The battery will eventually need replacement, and of course one has to take off the back of the watch to replace the battery. This is tricky and takes a steady hand. I wish Timex would make the battery more accessible so changing the battery would be as easy as sliding one in or out of a hinged door (like on a hearing aid). Obviously, there is much more to like about this watch than not like. I do recommend it for a good sport watch. It will withstand chlorine pools, lake water, rainfall, high and low temperatures, but be careful not to scratch the dial window! I scratched the main window crystal and ruined my last watch. Avoid spraying any kind of bug repellant on the window as well, as this can mar (dull) the surface. For me, this watch meets all my needs and I give it a 5-star rating. My needs are faily simple. There are certainly other watches that offer more features, but to me, the added features add complexity and are not worth the added bother. The price is good. The watch is good quality. This is a good buy. Jim "Konedog" Koenig

Great watch; but why the triangle screws?
Color: Black/Digital Gray/Silver-Tone
I have been using these watches for many years with very good luck, and would normally give them 5 stars. They are comfortable, waterproof, durable, and have an alarm and a countdown timer. (The waterproof and countdown timer - that can be set to repeat - make them good for sailboat racing, and these are much cheaper than sailing watches. ) But at some point before the watch breaks, the battery will die. It is not hard to replace the battery. Except now the watch comes with triangle head screws holding the back on, rather than the regular phillips head screws they used to have. Why? Is it that important to keep people from opening up their watch? Making things harder to fix is a step in the wrong direction. Knocking off one star for that.

Still the champ.
Color: Black/Negative Digital/Gray, Color: Black/Negative Digital/Gray
I absolutely LOVE my Casio GBA800 that I have bully bars on, so she's quite huge. Analog with Bluetooth, pretty cool. If I ever remember to use such things. I have a phone and laptop on me usually, why do I need to play with my watch? I want to tell time, that's it. Comes along a good sale for an Ironman, and I used to be a complete fanatic for only Ironman for a real person's needs. Why not, I've been fighting the Casio all day with my coat cuff, let's get something a bit slimmer for when it's coat season. See if they're still great. Yup! Sure is. It's been probably 25 years ago last time I wore this style of Timex, and can you believe the button setup and beeps are all still the same as way back when! And somehow, my subconscious remembers the button presses. Wild. This thing is light as a feather, and I got the inverse LCD for fun, which is cool as all get out, but takes some getting used to. The Indiglo sure looks awesome, though, and she's like Knight Rider down there. Stealth. The display is big, and easy even for my old eyes, the band is supremely comfortable, and there's a strap catch that actually works correctly! With no Bluetooth, battery life should be outstanding - always used to be. Back when watch batteries were like $12 each. There goes my allowance! Lol. I'm very impressed by this timepiece. I really didn't mean to order order it, but, oh well. I love it as much as my Casio. Affordable tough watches rock!

This Timex Ironman lives up to its name
Color: Black/Digital Gray/Black
Timex Ironman watches have been with me for a decade. This particular one I just ordered as a backup for the same one that I have had for seven years (and still works perfectly). I don't know why I ordered a backup except that I love it so much that I couldn't fathom the idea that Timex might discontinue this model. Why do I love it so much? Because it is functional in many ways. Aside from its durability, reliability and the fact that it fits on my wrist so comfortably, it is easy to read and extremely useful for tasks that need countdown alarms as well as regular timers (it has three which you can set). Since I gave up "fashionable" watches years ago in favor of practical, easy to read, multifunctional devises I found this Timex the best of all the other brands that I have tried in this category. Years ago, President Bill Clinton, who jogged regularly, was heavily chastised for wearing a very functional Timex Ironman watch in the Oval Office instead of what the professional politicians considered appropriate for a President. It was then that I realized how important it was for a person to wear a watch that they loved, and that was functional for them. At that point in time I had many other watches that I didn't jettison until later when I realized that I need only wear the watch that I loved and was useful to me. I still have another watch that I saved for "appropriate" times out but have only worn it once. The rest of the time my Timex Ironman stays on my wrist wherever I go.
