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.

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.

Fits in purse without a lot of bulk
I ordered this to use as a travel cross-stitch case on the recommendation of someone else. Surprise, surprise - It doesn’t work as a travel cross-stitch case! (I either shouldn’t have listened or I got the wrong kind). However, I do have a iPad and it ended up working great for that so I didn’t return it. Padding is good; everything fits; easy to use with a nice handle; the zipper is smooth; color is neutral; doesn’t add a lot of bulk so it’s easy to fit in my bag; provides extra protection although I don’t really need that; seams and stitching are holding up well to everyday use and it wipes clean. While it doesn’t work for my sewing while traveling, it does work everyday for “work”. So, don’t get this for sewing, but for your iPad (the actual intended purpose!!); for that purpose it works well. My mistake ended up being a plus and the price was good.

Perfect for my iPAD, cash, phone, & more
Size: 12.9 inch, Color: Indigo
I searched Amazon a few different times trying to find exactly what I was looking for. We're traveling out of country and I needed a couple of very specific things in a bag for my iPad. It has the padded space for the iPAD, then beside it is an equally sized space for whatever - money bag, etc....for me. T here's a front zipper pocket with a smaller pocket included holders for 2 pens. My time and energy paid off by purchasing this bag. The iPAD slides in lengthwise making it easily accessible along with the cash bag I'll be accessing frequently. Its qualit y, it looks very nice and its lightweight. I'm a happy camper. I recommend getting this bag. Oh, I will also carry my cell phone in the bag too.

A Very PROfessional looking bag for all my iPRO Mobile Devices!
Size: 13.3-14 inch, Color: Dark Gray
Moko products usually meet my expectations and this little bag is no exception. It’s the perfect size for an iPad in a fully enclosed case. The front pocket is ideal for cords, backup charger battery, pens, notepads, iPhone, etc. We (husband and wife) are both in our 80’s and sometimes need to take our iPads to medical appointments because it’s often hard to see everything we might need to see on a regular iPhone screen. We bought a dark blue one in January for my husband to safely take his new iPad to work so he could read kindle books during his breaks. The day after I ordered it, he had to retire under VA Disability. Still, it has come in handy as we take care of paperwork, etc. I liked his so much that I ordered this gray one last week. The size, style, colors, etc make them look very professional. The bag is small enough that even I can lift and carry it. (It’s too small for use with a full-size laptop especially if it has a case of any kind.) I have the 2025 iPad Pro (M5) and my husband has the 2025 iPad (A16). We both have the 2025 iPhone 17 Pro — mine is the regular size and his is the Max. Both are in completely enclosed cases. It is a necessity to have a secure way to use our mobile devices away from home, and these bags are perfectly compatible with everything we need to carry around in them as protection for our valuable devices. The MOKO cases are stream-lined, easy to use, not bulky but padded enough to give protection. Best of all, the price is quite good for an item of this quality. At $30 @, I suspect they could possibly outlast us! They also should be easy to spot clean if necessary. I find I can keep my magnetic paper-feel screen in the inside pocket to use with my iPencil Pro, which I can store in the smaller front compartment. In fact, I will probably keep all my accessories in the bag, then just add my iPad when I need to take it with me. I’m glad we both have our own and highly recommend this if you are looking for a bag for this purpose.
