When iHarmony® zoning is installed in your home with iComfort®-enabled equipment from Lennox and an iComfort S30 ultra smart thermostat, every family member can have individualized temperature control for their own part of the home.


Year-round energy savings

iHarmony zoning isn’t just about customized comfort and precision. It can also help you use less energy every day. An iHarmony zoning system lets you reduce heating and cooling to unused rooms, so you don’t waste energy conditioning air that nobody will feel.

Use your phone to control zones remotely

Each zone in an iHarmony zoning system can have its own individual schedule, so your heating and cooling can more closely match your routine and lifestyle. You can control the zones with an iComfort S30 ultra smart thermostat or iHarmony in-zone thermostat. You can also adjust the temperature in any zone remotely with your smartphone, tablet or other web-enabled device.
