Harmony III™ Zoning System

Four-Zone System
 
Room to room temperature control for multi-stage variable capacity equipment. When paired with advanced heating and cooling systems from Lennox®, Harmony III™ zoning can regulate temperature to as little as one degree* of the thermostat setting. Harmony III divides your home into as many as four areas, giving you more options for controlling your family’s comfort. So your home is perfect from room to room and floor to floor.
 
With Harmony III™ zoning, you don’t have to waste energy by heating and cooling unused or little-used parts of your home. So, you stay as energy smart as you do comfortable. Harmony III™ delivers its best performance when combined with advanced Lennox equipment, but it can work with most any home comfort system. It can be an ideal solution if you have:
 
Top floor that’s always warmer than lower floors
Large windows in your home
Family members with different temperature needs
High heating and cooling bills
