What does it mean if the code H1 appears on my Inverter air conditioning unit, heat pump during use for heating?

The code H1 that appears on your air conditioning unit means that your appliance is performing an automatic defrosting cycle due to the temperature and humidity of the outside air. The cycle protects the outdoor unit from the formation of ice, from possible breakage of mechanical parts and it improves output in the room when operation resumes, which will take place automatically after a few minutes, during which time the air conditioning unit will not produce any air.
