Product Overview

The iComfort E30 Wi-Fi enabled smart thermostat is a universal thermostat that works with non-iComfort-enabled and non-Lennox products. Introducing four new features to the iComfort E30 that help control a home’s environment. The iComfort E30 now pairs with any Google Assistant device, a perfect addition to the already compatible Alexa and Siri devices. If This, Then That (IFTTT) can help program the iComfort thermostat around a homeowner’s schedule. It brings home automation apps together for the ultimate comfort experience. To display a more personalized custom backdrop, the new picture upload capability allows a personal photo to be uploaded via a smartphone and the iComfort App. The iComfort E30 universal smart thermostat outperforms the rest by monitoring system operation in real time, with ventilation control the dealer gets alerted when it’s time for a filter change or repair, making sure the system always performs at its best and eliminating the need for a separate ventilation control panel.
  • Feels Like™ Setting:  Similar to the “Feels Like” temperature in a weather report, this takes into account temperature and humidity, making your home feel exactly like you want.
  • Allergen Defender: Monitors the air quality and pollen levels in your local zip or postal code and automatically turns the system fan on as needed to clean your home’s air.
  • Perfect Temp:  Allows you to set the ideal temperature. The system then automatically adjusts heating and cooling to maintain that setting.
  • Smart Away™ Mode: Uses the location services in your smartphone to detect when you’re leaving, and automatically changes the temperature to a more energy-efficient setting.
  • Schedule IQ™ Technology: Allows you to program your thermostat once. Whenever there’s a change in your routine, the thermostat adapts heating and cooling to match.
  • Performance Reports: Provides you with historical data on your system’s operation and performance. It tracks temperature ranges, how long the system runs each day and more. Daily and hourly reports are available via the homeowner portal site, Monthly reports are emailed to you directly.
  • Alexa Integration: The iComfort E30 smart thermostat is an Amazon® Alexa-enabled, smart-home-compatible thermostat. It works with Amazon Echo, Echo Dot and Tap devices allowing the homeowner to ask Alexa to adjust the temperature.
  • Weather-On-Demand: Live up-to-date weather data and seven-day forecasts.
  • Emailed Alerts and Reminders: Notifies you and your dealer of any service or maintenance needs.
  • Peace-Of-Mind Protection: Five years in residential installations and one year in non-residential installations. Refer to Lennox Equipment Limited Warranty certificate included with unit for specific details.
