Flexizone Ducted Zoning Solution

what is flexizone?

Flexizone is Mitsubishi Heavy Industries’ proprietary zoning solution. Easily integrated into any Mitsubishi Heavy Industries ducted system (including our FDU series, FDUA series, FDUM series), the Flexizone zoning solution gives more control of your ducted system by allowing you to turn individual zones on or off.

This provides much better control over your home’s climate and allows you to save energy by turning unused zones off.
