The MRCOOL DIY Multi-Zone 48,000 BTU 22 SEER2 5 Zone Ductless Heat Pump Split System - 9K + 9K + 18K + 18K + 18K 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 48,000 BTU 22 SEER2 Five-Zone Ductless Heat Pump Split Air Conditioner System - 9K + 9K + 18K + 18K + 18K 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 21.8 SEER2 Five-Zone Ductless Heat Pump 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.

MRCOOL® 48k DIY 5th Generation 6 Zone Multi-Zone Mini-Split Condenser 230v
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! Once you install your condenser, you’re entitled to a 5 year parts warranty, a 7 year compressor warranty, and, if you subscribe to the MRCOOL® Care Program, a Limited Lifetime Replacement warranty. The MRCOOL® DIY® is the right choice if you want fast, efficient comfort that won’t let you down!

Nice and comfy, light duty and feel great.
Size: X-Large, Color: Light Green
What they may lack in "durability" i.e. very light and thin = not going to last all that long, they make up for in fit [yes even for wide shoulders], comfort and style. If you want them to last, suggest a gentle cycle and just take ot easy on them. They are light, thin, and airy. Nice summer shirt.

A true vacation find!
Size: Medium, Color: Light Green
Really nice choice. Got it for my husband and he really liked the style. I loved how it fit on him and the lightness of the fabric. Great for hot, sunny weathered days, or warm nights. A true vacation find. Both comfy and stylish. He would have preferred it be 100% cotton, but I think he didn't really mind after steaming it. He commented on the color too. A beautiful sage green!

Well made, comfortable and flattering
Size: 3X-Large, Color: Light Green
Nice material. I ordered the 3XL because my hubby has a big belly. It fit him well and was slimming. He wore it as a guest to an outdoor wedding. He looked nice and was comfortable all night.

Nice but short
Size: X-Large, Color: Lavender
Yes, I purchased this shirt for my husband to wear on Mother’s Day. He looked so handsome and the color complimented his skin tone beautifully. The only con that my husband expressed was that the shirt was short but was comfortable and the fabric felt good on his skin. He is 6’3” and usually wears an XLT. Coofandy, Please make these shirts for taller, longer torso men!

Expensive Look Without The Expense!
Size: Medium, Color: Black, Size: Medium, Color: Black
Sizing: If you’re a true large like me and close to but less than fifteen pounds overweight, normal length and with a 44” chest, buy a medium and use the shirt to inspire you to lose the beer belly. If you have similar dimensions but are overweight by up to thirty pounds, get the large. Materials: The mediums are manufactured to 70% synthetic, 30% linen—which is a great mix, as is doesn’t have to be ironed after it’s washed and hung to dry, nor does it have to be ironed every time you get up from a chair. I’ve had many 100% linen shirts and sure, they look great after you spend thirty minutes ironing them, just to look like a crumpled up newspaper after you get out of your car. My experience with linen shirts is what brought me here. Unboxing the shirt: I threw it on an ironing board the moment I unbagged it. I tried the Synthetic setting on the iron—it wasn’t enough. I then tried the Wool setting and set the steam setting to constant medium to high. It worked great. I didn’t have to press down at all, just lightly glided the iron across wrinkled areas of the shirt. Within five minutes, the shirt looked like a hundred-dollar shirt. The material is light, yet feels heavy to the touch and breathes very well in the heat. The hidden buttons give a clean, modern look that allows the shirt to be worn with anything from shorts and sandals to dress slacks and shoes in a club. I like to wear these shirts, untucked with a pair of jeans and western boots. This shirt is very comfortable, fits nice and is extremely versatile.
