As of 2015, Honeywell makes one round programmable thermostat model that is called the Lyric thermostat. The company also offers several round digital and manual nonprogrammable thermostats.
The Lyric thermostat is a sleek device with a round temperature display and minimal controls as most of the thermostat's functions are controlled via smartphone. The mobile app-based installation takes just minutes, and shortcuts at the bottom of the app allow for quick temperature changes. The thermostat's Geofencing feature detects when no one is home using the smartphone's location to save energy. It also features Smart Cues that send alerts concerning filter changes and temperature warnings to the homeowner's smartphone. The device includes a Fine Tune feature that creates an ideal environment based on both temperature and humidity.
The Lyric is compatible with most heat pump, heating and cooling systems, but it does not function with electric baseboard heat. The thermostat app works with Android and iOS platforms, while the router must be set up for dynamic host control protocol. The seven-day programmable thermostat calls for professional installation, and it is available for purchase online, from a Honeywell contractor and at select retailers. To meet the needs of a diverse range of homeowners, a number of other square and rectangular programmable thermostats are also available from Honeywell.
