The iComfort® S30. The smart thermostat that adapts to your life. Perfectly.

Your schedule may change. The weather may change. Even the air quality in your neighborhood may change. But the iComfort® S30 thermostat adapts to deliver the ultimate in energy savings, comfort and peace of mind.

Energy Savings

Anytime your routine changes,
the iComfort® S30 smartly adapts.

With a standard thermostat, you pre-select temperatures for the day and week. It stays on a fixed schedule and won’t adjust temperatures when your routine changes.

Save energy when you're away.
But always come home to comfort.

The iComfort S30's Smart Away Mode uses the GPS in your smartphone to detect when you're leaving, and automatically changes the temperature to a more energy-efficient setting. If you or a family member returns home, Smart Away then returns your system to a normal schedule and comfortable temperature.

The iComfort® S30 does the
thinking and scheduling for you.

With the Schedule IQ feature, you only need to program the thermostat once. Whenever there's a change in your routine, the thermostat adapts heating and cooling to match.

The iComfort S30's Allergen Defender monitors the air quality and pollen levels in your area, according to your zip code and automatically turns the fan on to clean your home's air when outdoor levels are high.

Balanced Temperature and Humidity

The iComfort S30's Feels Like feature creates the temperature you want to feel, not just the temperature you set—much like "Feels Like" temperature in a weather report. So when you set it to 72˚F, it feels like 72˚.

Part of the Ultimate
Comfort System

As part of a communicating system, the iComfort S30 can get more performance out of every piece of equipment.

  • The iComfort S30 can adjust the cooling capacity of premium Lennox® equipment to fine-tune energy efficiency and comfort with even greater precision.

  • When paired with premium Lennox furnaces, the iComfort S30 can increase or decrease heat output in increments as small as 1%, so you always use just enough fuel to stay warm.

  • Since it monitors the air quality in your neighborhood, the iComfort S30 knows when to turn on the fan to clean the air in your home. When combined with PureAir, it cleans the air in your home better than any single system you can buy. The thermostat also alerts you when it’s time for a filter change.
