In winter, set to heat once set temp is reached. The heat pump will slow down and idle along or stop. Set your louvre to point on the floor ½ way into your room and the fan on auto this will heat the cold on the floor first and it will rise to the ceiling. The heat pump will suck it up and send it to the ground again. In summer set to cooling. Point the louve up in the air and auto fan. This will give you nice even cooling as cold air drops. Set the fan on Auto mode. This will quickly heat/cool the room and will then slow down and maintain the required temperature which will be energy efficient. Auto mode for heating and cooling uses more power as it constantly switches between both modes to maintain the set temp and the heat pump is constantly running using more power.
