Ductless Heat Pump Modes
Because the “Auto Temperature” mode automatically switches between heating and cooling based on indoor temperature, the system could start heating on a cool summer night or cooling on a sunny winter afternoon. It could also lead to heating and cooling battles between HVAC systems. Residential customers should set the heat pump mode to “Heat” in the winter and “Cool” in the summer, rather than using the “Auto Temperature” mode. Your installer may suggest the “Auto Temperature” mode in some commercial settings.
