ENERGY STAR certified to help save energy, track your heating and cooling and send personalized tips on reducing energy use.

SAVE ENERGY AND GET REWARDED by checking with your energy provider about available energy savings rebates to save on your purchase. Plus, eligible customers can enroll in their local Utility's "DEMAND RESPONSE PROGRAM" which can reward you for allowing the utility to slightly adjust your AC or furnace temperature settings when there is high energy demand.

CONTROL FROM ANYWHERE by using the app or compatible smart home partners including AMAZON ALEXA, GOOGLE ASSISTANT, MICROSOFT CORTANA, and more. Flexible programming options are also available if you'd rather set it and forget it but still benefit from energy savings.
