    Notes

    • Different models of all available matching indoor units can be combined in any order to create a multi zone split system, up to a quantity of the number of available circuits.
    • Not all available circuits need to be utilized with an attached indoor unit. 66% or higher of the total capacity utilization is recommended.
    • Every indoor unit attached to a multi zone system will operate at a random, self-regulated capacity, based on the actual demand it measures from the zone it is serving (Between 30% to 100% of its rated capacity) or turn OFF as needed.
    • Outdoor unit will also self-regulate its total output capacity, based on the total demand it reads from all the simultaneously running indoor units at any given moment, up to its maximum rating capacity.
    • With multi split systems, the total demand from the outdoor unit, will seldomly exceed 75% of the total available capacity of the combined indoor unit group due to load fluctuations of each indoor unit.
    • Therefore, total attached indoor unit capacity can be selected up to 133% of the supporting outdoor unit's rated capacity.
    • Although very seldom, if the total demand from the combined group of indoor units' exceeds the rated capacity of the outdoor unit, the capacity of the each indoor unit will be annotated accordingly.
    • For high demand applications, max loading limits may need to be reduced up to 20% to avoid underperformance risks during some extreme conditions.

        Stylish Pebbled Leather Pochette With Great Quality and Everyday Ease
        Size: One Size, Color: Red Jam
        This leather shoulder bag/pochette feels really nice in hand — the pebbled leather has a soft, supple texture that looks more refined than you might expect just from pictures. The stitching and hardware feel solid too, which gives confidence that it’ll hold up well with regular use. It’s compact enough to be easy to wear around town but still roomy enough for your essentials like phone, wallet, keys, and a few small extras. I liked how the design balances casual and polished — it pairs just as well with a simple daytime outfit as it does with something a bit dressier for the evening. The strap is comfortable, the zipper works smoothly, and overall it feels like a quality piece rather than something flimsy or basic. If you want a handbag that feels a bit elevated without being too large or flashy, this one delivers nicely.

        Perfect color and size.
        Size: One Size, Color: Biscotti, Size: One Size, Color: Biscotti
        Gorgeous! Bought the biscotti color on sale at $209 but would have paid full price! I’m 5’2 and carrying it as a shoulder bag is perfect. I thought the strap might be a tad too long so super happy!
