Smart Away
Flair will use the Away Temperature Minimum and Away Temperature Maximum to control the home temperature. If Set Point Controller is Thermostat, Flair uses your smart thermostat Away values to control the home temperature.
Off Only
Flair will turn off systems when your home is set to Away. If Set Point Controller is set to Thermostat, Flair will turn off mini splits, and use your smart thermostat Away values to control the home temperature for Smart Vent operation.
