Will my Lyric work with my dual fuel heating system?

Currently only the Lyric Round and the Lyric T6 Pro (TH6320WF2003) thermostats are compatible with most dual fuel heating systems. These are heating systems that combine a heat pump with a gas furnace. Your Lyric app will walk you through configuring your Lyric Round or Lyric T6 Pro thermostat to work with your heating system.
