Press the mode key on the remote control and select the icon with the sun for heating.

As shown below: according to the primary mode of cooling, and then according to the primary heating.

Air conditioning and heating will use freon, which has the characteristics of condensation, liquefaction, exothermic evaporation and gasification and heat absorption.

When the air conditioner is heating, the compressor will pressurize the gas Freon, making it a high-temperature and high-pressure gas, and then condense and liquefy it through the heat exchanger of the indoor unit, releasing a lot of heat and raising the indoor air temperature.

The fifth icon in the above picture is heating.
