The MRCOOL DIY Multi-Zone 36,000 BTU 22 SEER 4 Zone Ductless Heat Pump Split System - 9K + 9K + 9K + 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 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 36,000 BTU 22 SEER Four-Zone Ductless Heat Pump Split Air Conditioner System - 9K + 9K + 9K + 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 36,000 BTU 22 SEER Four-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.

Small for a medium
Color: Red-Blue, Size: Medium Size 2 (6"), Color: Red-Blue, Size: Medium Size 2 (6")
I got medium.. and it does not look like a medium ball.. it’s rather small. It’s pretty sturdy and my dogs went crazy for it but it’s definitely not the size I thought it was going to be 😂 my dogs chewed one strap within 5 minutes of having it but they’re dogs and that’s what they do lol. I bought this to be an outside ball for them! It’s pretty light but that’s probably because it’s small. Not soft? But feels like a soccer ball. It also had no smell coming out of the box. Also comes with a pump and an extra thing to put in the ball to pump in case you lose one. I like these balls, I expect them to be chewed up because that’s what I bought them for! Fun for my dogs and they are! But the size… it is not medium and that’s the only reason for 3 stars 😂😂😂 Other then that I recommend, your dog will definitely love this! Inside or outside playing! Alone or with another dog!

Great toy for a GSD
Color: Blue Gray, Size: Extra Large Size 5 (9")
My GSD loves to grab the flaps and shake her head with the ball bouncing of the side of her head. This is her favorite toy. I thought she would puncture it but it has held up great since she likes to grab the flaps rather than biting the ball.

My puppy LOVEs this ball
Color: Glow in the dark I, Size: Medium
I saw someone recommend this ball in a facebook group. I ordered the first one and it is now sitting somewhere under my deck and I can't find it. My dog loved it so much I had to order a second one. I think the fact there are so many tabs it makes it easy for him to grab it and run so very functional. He doesn't always like to share. The glow in the dark ability I would rate that good at all. The rest of the ball is good quality and holds up well against my aggressive chewer. Its easy to throw or kick. It isn't super hard but is holds it shape well. My dog is about 8 months old and is a mini goldendoodle. I think he was about 18lbs in the video. Perfect size for him. I would definitely recommend, I think your dog would love it!

Corgi goes crazy for this ball
Six months now, still five stars. It is still easily our Corgi’s favorite ball & she still enjoys it all kinds of ways. Rather than tiring of it she likes it even more. She really likes the tabs that make it so easy to grab & hold onto. The ball is all roughed up & torn up still but held up well & has not had to be pumped back up at all. As others noted a small manual ball pump, about 10” with i think 3 different attachments, is included with each order. The glow in the dark stuff is apparently a coating of some kind which has been totally rubbed off. I used an art pen with glow liquid to trace the pattern on the ball for a glow refresh, we’ll see how long that lasts. It is hard to find toys she likes that much, i highly recommend! Our Welsh Corgi goes nuts for this slightly smaller size soccer ball. She had a full-sized ball that we left slightly deflated so she could run with it. This one is even better than i ever would’ve guessed it would be! The tabs, including a longer tab useful as a handle for humans, make it easy for her to grab it or run all over playing keep away with it. Not interested in herding this ball when she can run all over the yard with it or carry it everywhere with her. She’s a super strong chewer in spite of being small so it is extra durable by our tough standards & it appears that it will last at least a year im guessing. Quality materials & craftsmanship. It’s held up over a month - roughed up but not excessively. The glow in the dark feature is not as bright as the photos - don’t buy it just for that - but it glows some given enough daytime sun, and a dark night so the glow can show. Only the top side of the ball that’s facing up can absorb the sunlight at a time so it’s unlikely that the entire ball could get the amount of sunlight needed to glow brightly all at once. All and all this is the best, most well used toy purchased for her during her one year with us, well worth the $$ and recommend buying it if your pet enjoys balls, keep away, herding, and/or fetch, anything like that. She also likes to hide it from me, just the right size for that.

Pawsome product!
Color: Glow in the dark I, Size: Medium
Pawsome for our doggos! We have bought 5 because the puppy chewed the tags off. Our dogs are border / aussie mix and love the challenge of these balls. We named them "Wilson" because they treat them like their best friend.
