How does Flair switch between heating and cooling? – Flair

Overview

When Mode is set to Auto Heat/Cool, Flair will intelligently switch between heating and cooling. This is often called auto changeover.

Flair's mode switching feature can be used with the following types of systems:

Systems with mini splits
Systems with integrated smart thermostat(s) with Flair as the Set Point Controller
Systems with mini splits and integrated smart thermostat(s) with Flair as the Set Point Controller
Systems using Flair Puck Pros as integrated controls: Flair will switch between heating and cooling when mini splits are running

Mode switching is not available for these types of systems:

Systems with an integrated smart thermostat with the thermostat as the Set Point Controller: Flair follows the mode and set points read from the thermostat
Systems using Mirror Mode: Flair follows the mode and set points read from the thermostat
Systems with a non-integrated thermostat: when Flair’s Mode is set to Auto Heat/Cool, Flair will follow the thermostat by reading the duct temperature to determine if the system is in heating or cooling

Please note the following:

Flair does not use the Auto Heat/Cool mode on a smart thermostat. Flair will set a smart thermostat to either Heat or Cool mode.
Flair does not use a dead band. Flair will continue to make adjustments to a smart thermostat when Mode is Auto Heat/Cool.
