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 9K and 12K BTU Ceiling Cassettes are protected by a limited lifetime warranty in addition to a 7-year compressor warranty and 5-year parts warranty.

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 four 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 48,000 BTU 22 SEER2 Four-Zone Ductless Mini Split Air Conditioner System - 9K + 9K + 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 48,000 BTU 22 SEER2 Four-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.

LONG DESCRIPTION
We’re excited to introduce our new 5th Generation MRCOOL® DIY® 48k BTU Multi-Zone Ductless Mini-Split Condenser, because it’s better than its predecessor in nearly every way. You won’t need the services of an HVAC professional when you’re setting this unit up, because you can do it yourself, which saves lots of time and money! This condenser enables you to heat and cool up to 6 separate spaces equalling up to 2,000 sq. ft., meaning you’d be able to cover an entire home in the completely efficient comfort of a single DIY® system. You can install this system on your own because our innovative, patented pre-charged Quick Connect® line sets allow you to skip the lengthy and complicated process of evacuating and charging the system. These line sets are filled with R-454B refrigerant, a much more ecological and proficient upgrade from the previous refrigerant used in the last generation. This switch helps the system achieve impressive efficiency levels, like 21.8 SEER2 and an HSPF2-4 of 10. These line sets are sold separately. Once you install your system, you’ll be able to explore the variety of ways you can customize your comfort. For ultimate control, you can integrate system operations with the SmartHVAC app, available for Apple and Android phones, allowing you the ability to set schedules, manage modes of operation, monitor your systems all with the touch of a button. The app even enables you to set up integration with Amazon Alexa and Google Home, meaning you won’t have to move a finger to make your home more comfortable than ever. We pride ourselves on having one of the best warranties in the industry on this unit!

Be ready to question everything and everyone…
Format: Kindle
We Used to Live Here definitely nails the creeping sense of dread and paranoia throughout the story. I constantly questioned whether Eve was truly unraveling or if she was the only person actually sensing danger, and the added news articles, interviews, and scientific discussions throughout the book made the atmosphere even more unsettling. I also connected with Eve’s struggles surrounding anxiety, people-pleasing, and past religious experiences, which added an emotional layer to the horror for me. That said, the pacing felt super uneven. Most of the story takes place over only a couple of days, but it dragged at times and honestly felt like it would work better as a movie than a book. Things finally picked up around the 70% mark, but the ending left me wanting much more explanation and payoff than we as the readers received. Overall, this was an eerie, anxiety-inducing read with a fantastic atmosphere, even if the execution didn’t fully land for me.

Format: Paperback
I liked the pace, the story and the characters. Sadly I found it at the end a bit confusing. I think the book needed more edition work. Otherway, it is a recommendable book if you want horror with a bit of science fiction. Be advised you'll need to use your imagination to understand certain pasages.

Not even a good read. Pass it.
Format: Paperback
Unfortunately, this book was basically a whole lot of nothing. It was not what I was hoping for, which was on the edge of your seat scary. It was not even alittle scary. Left me with unanswered questions and confused. Sorry..I did not like this book at all.

Easy to read and fall in love with
Format: Hardcover
one of those books that feels less like a story and more like an experience. Ray Bradbury captures the magic of summer, childhood, and all the little things in life we take for granted. I loved the way it blended nostalgia with those bittersweet moments of growing up. It’s slow at times, but that’s the beauty of it — it makes you stop and notice the small details, just like the characters do. For me, it felt like stepping back into a simpler time, but with all the emotions and lessons that still matter today. It’s warm, reflective, and beautiful. A book you don’t just read — you feel.

Vintage Bradbury
Format: Hardcover
Ray Bradbury August 22nd 1922 - June 5th, 2012 When Ray Bradbury died reactions came from everywhere including from President Obama. Surprising to me, few mentioned the one of his works that meant so much to me and affected my life so deeply. While he was most known to the general public for his science fiction, I found his mostly autobiographical novel Dandelion Wine to be the most impactful. At the same time it best illustrated Bradbury’s incredible command of the language, his ability to stir the imagination, and the way in which he could open windows on life. I couldn’t count the number of times I would reread a single sentence and become overwhelmed with admiration and envy at how he used words to create images in the mind’s eye. All this was particularly on display in Dandelion Wine and its sequel, Farewell Summer. For Bradbury, it couldn’t be just water. “Nothing else would do but the pure waters which had been summoned from the lakes far away and the sweet fields of grassy dew on early morning, lifted to the open sky, carried in laundered clusters nine hundred miles, brushed with wind, electrified with high voltage, and condensed upon cool air. This water, falling, raining, gathered yet more of the heavens in its crystals. Taking something of the east wind and the west wind and the north wind and the south, the water made rain and the rain, within this hour of rituals, would be well on its way to wine.” Essentially, Dandelion Wine is the story of a summer in the life of a twelve year old boy as he comes to understand what it means to be alive. But it is also a time capsule for the year 1928 of life in a small town when everyone’s world was much smaller and more compact. There is horror, love, comedy, wonder, nostalgia, and human relations. Bradbury could find unique ways to describe them all. I first read Dandelion Wine in 1957 when I wasn’t much older than Douglas Spaulding, the central character. It helped me put life in perspective as I was leaving high school. I read it the second time in the early ‘80s when I introduced my daughter to it. Kelly and I sat on our front porch swing one warm summer evening and I read aloud to her the story of Bill Forrester and Helen Loomis. It was all I could do to finish it and when I did we both had tears streaming down our cheeks. Such was the power of imagination and Bradbury’s ability to stroke it to life using just words. I read it the third time in preparation for reading the sequel, Farewell Summer, written 55 years after Dandelion Wine. Like a fine wine, it had only gotten better with age. Appropriately, Farewell Summer was given to me by Kelly and I read it on summer’s eve 2012. It was the perfect beginning for yet another summer. In both books the ravine in Green Town, Illinois, based on Waukegan, Illinois where Bradbury grew up was a central feature. I couldn’t resist going to Googlearth to see if the ravine was real. It was. And, it is still there even after Waukegan had changed from a small town to a satellite of Chicago. I was pleased to simply find I could locate it. But when I zoomed in and highlighted the little tree symbol I found the ravine is now Ray Bradbury Park. Perfect! Dan Winters June 29, 2012
