In heating mode, if the room temperature is already higher than the set temperature, the outdoor unit stops operating, and the indoor unit fan rotates at a very low speed.
Click steps to track your progress.
Check the current room temperature and compare it to the set temperature on the remote controller.
This indicates the unit is efficiently maintaining the desired temperature and does not need to run at full power.
Adjust the set temperature higher if more heating is desired.
