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 increases system efficiency. 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.

Get Allergy Relief Exactly When You Need It

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 the “Feels Like” temperature in a weather report. So when you set it to 72 F, it feels like 72.

Home Comfort, Made Perfectly Simple

Set the iComfort® S30’s Perfect Temp, and your system will heat or cool as needed to maintain your temperature in any weather, year round.
