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 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.

Love this book bag
Color: Camel, Size: Standard 15.6 Inch
Great backpack, fits a lot of stuff and is very flexible. Zippers work great, and I love how easily it closes. It’s made of washable material and has many compartments to stay organized.

Great Bag but needs double zippers
Color: Black, Size: Standard 15.6 Inch
Love the bag, its cute, light weight, has lots of pockets and is travel friendly. My only wish is that the larger compartment had a double zipper so I could open from either side. All my other backpacks have double zippers, didn't realize how much I would miss that.

Great for carry-on bag
Color: Camel, Size: Standard 15.6 Inch
I loved this bag. I bought it to use as a carry on for a flight. It held everything I needed it to with room to spare. I didn’t not have a laptop or large tablet, but there would have been ample room for either. I carried all of my chargers, a couple of books, meds, sunglasses, a hat, an owala water bottle, snacks, and a phone. It was comfortable and ideal for traveling and stowed perfectly under the plane seat.

Love it
I really like this handbag. The pebbled leather texture looks elegant and feels good quality. It is small but still fits my daily essentials like phone, wallet, and keys. The top handle gives a classy look, and the adjustable strap makes it easy to wear as a shoulder bag. The magnetic closure is convenient and easy to open and close. It looks stylish for both casual and dressy outfits. I am very happy with this bag.
