Why Won't My Ecobee Thermostat Switch Between Heating and Cooling in Auto Mode?

Smart Thermostats • Ecobee Smart Thermostat

Your Ecobee thermostat stays stuck in heating or cooling mode and will not automatically switch between the two when set to Auto. The home may overshoot the cooling setpoint without turning on AC, or the heat runs even when the temperature is above the heating setpoint. Auto mode requires a minimum temperature differential between heat and cool setpoints and depends on correct HVAC wiring configuration to function properly.
