iHarmony® 4-Zone System

A major advance in precision climate control.

An environment exactly how you want it

Used in combination with premium Lennox^® equipment, iHarmony^® zoning puts heating and cooling where you want it, redirecting airflow to specific areas of your home as needed. So your temperatures stay consistent, from floor to floor and room to room.

Change the temperature throughout the house, or change it in specific areas

Every zone has its own independent thermostat that maintains your set temperature. Adjustments to zone temperatures can be made at each thermostat, and you also have the option of adjusting every zone at your main thermostat.

Smarter comfort and energy use

With iHarmony^® zoning, your comfort isn’t just more customized—it’s also more energy efficient. By redirecting heating and cooling away from unused or little-used rooms, you aren’t wasting energy on comfort nobody will feel.

Use your phone to control zones remotely

When you combine an iHarmony^® zoning system with an iComfort^® thermostat, you can adjust the temperature in any zone remotely with your smartphone, tablet or other web-enabled device.
