temperature by controlling conventional or iQ Drive compatible components within the heating and air

conditioning system. Easy-to-use operating modes (HEAT, COOL, AUTO, or E HEAT) activate cooling

electric heater, gas furnace or heat pump/electric heat combination) when the temperature gets colder.
