  • Ventilation control:The control of ventilation refers to the physiological mechanisms involved in the control of breathing, which is the movement of air into and out of the lungs, ventilation facilitates respiration.
  • humidity/dehumidifier control:Humidity control systems add or remove water vapor from indoor air to stay within proper humidity ranges.

The differences

Apart from the main differences that we have gathered in the table below, there are a couple of differences in the core features that gives Ecobee 3 Lite an upper hand over Honeywell Lyric Round 2nd Generation.

The first one is the too much reliance of the Honeywell relic features on the smartphone app. In Honeywell Lyric thermostat, many features work solely on the installation, use, and customization of the smartphone app. On the other hand, the Ecobee has occupancy sensors and remote sensors that provide accurate signals and inputs for the thermostat to make better decisions.

The second one is about the Geofencing technology. The Honeywell Lyric relies on its servers to operate Geofencing. This means that any fault in the Honeywell’s servers results in the failure of the Geofencing feature in the Honeywell’s thermostat.
