The MRCOOL DIY Multi-Zone 48,000 BTU 22 SEER2 4 Zone Ductless Mini Split System - 9K + 12K + 12K + 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 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 + 12K + 12K + 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 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. 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!

Tumbler and mug heat press
Style: Purple-30oz
Easy to set up and operate, heats up fast, and works beautifully. I sublimated 2 coffee mugs and they came out nice. It came with a small package of sublimation paper, heat tape, and a pair of very small heat-proof gloves. Gloves are needed to handle hot items, so you may want to get a larger pair. I have small hands and they barely fit me. But the heat press works perfectly.

Barely qualifies as a product
Style: 12x10
This thing is a FAIL on so many levels that I can't even begin to describe how bad it is. I bought the 12 x 15 press because I thought it would be fun to have a smaller press at the house that I could use to knock out things like mouse pads and coasters when I didn't feel like going to my studio and using my other machines. What a mistake. Uneven heat is just one of the issues. The biggest problem is that when you pull the arm down instead of the springs, adjusting to any height that might come from a coaster or a mouse pad, the whole heat plate just gets pushed back in the pylon, while at the same time, the platform holding the unattached rubber plate tilts down at the front, causing it to sit crooked and not work. It overheats the pieces in the back and under heats the pieces in the front because of the gap it creates.. It's awful . The timer didn't work . The temperature begins to go down as soon as you start applying the heat plate. It ruined everything it touched . Lesson learned - I've been in this business for a long time and I should've known better but I thought for the light duty minimal requirements that I wanted this would probably be OK but it's dismal . It's beyond dismal - buyer beware - don't say I didn't warn you.

Great machine but...
Style: 5in1-15x15-Blue
Great machine for the price. Served it's purpose well but after about 4 months of moderate use, the control box malfunctioned. OK, cool. Let's replace the control box. Easy, right? Wrong. You won't find a replacement here on Amazon. Maybe not anywhere on the internet. Luckily the warranty has me taken care of. Purchase with caution and know that this control box has a 5 pin input that you're not gonna be able to replace if it breaks or malfunctions.
