The three MRCOOL DIY Multi-Zone air handlers included in this set provide directional control of the heated or cooled air.

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.

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.

arm holes too large, shirt too long, size down
Size: Small, Color: Wine
I am 110 pounds and 5’2”. I ordered a small. The fabric feels awesome. The neck area and straps are perfect. However, the arm holes are quite large. The bottom of the arm hole isn’t straight down, flush with the shirt. It angels outward. If you lift your arms up it looks odd. I should have ordered an extra small. But even if I do that, I still think the arm hole will look odd. I will likely return this or wear it at night or at the gym with yoga pants. The shirt is a tad bit long. If you wear short shorts, the shirt would cover your shorts.

WELL CONSTRUCTED. GOOD STITCHING ON NECKLINE AND SLEEVES. GOOD FOR TALL PERSON.
Size: X-Large, Color: Orange
The Automet women's loose-fit tank top is sized just right for me. I'm 5'11', 200 lbs., 57 years old. I've got some back fat that would be obvious in a tight top. This tank is loose enough to hide my back fat but not too loose. From the front, it does not appear loose at all. It's the back area that has extra room. It has a nice, scooped hem. One special feature is the double stitching on the neck and shoulders. It is well-made. It looks more expensive than it is. I bought the Automet tank top in the color orange. It is NOT see-through, nor is it thick. I live in Arizona, in the desert part, where it gets hot. This tank is thin enough to keep me comfortable from May to October when the heat hits. It's hard for me to find the "perfect" tank. I've tried so many. I feel you would be wise to give this tank a try. Worst case, you return it. I love the orange one so much, I plan to purchase all the colors for this hot summer coming up. I wish all of you the same happiness I have found with the Automet tank top.

The perfect throw-on athletic dress (with built-in shorts!)
Size: Small, Color: Navy Blue
I’ve been loving this athletic dress—it’s one of those pieces that’s both functional and cute, which is hard to find. The fabric is lightweight, breathable, and slightly stretchy, so it’s comfortable whether you’re running errands, going for a walk, or just chasing kids around all day. The built-in shorts are a huge plus. They stay in place well and make it feel more secure than a regular dress, especially on busy days. I also appreciate the pockets—they’re actually usable and don’t feel bulky. The fit is relaxed and flowy, which I personally like because it’s easy and flattering without clinging. The straps are adjustable, so you can customize the fit a bit depending on your height or preference. I’d say it runs true to size for a looser fit. If you want it more fitted, you could size down, but I like the casual, sporty look as is. Overall, this is a great everyday summer staple—super easy to style with sneakers or sandals, and perfect for travel or on-the-go days. I’ll definitely be getting more colors!
