Defrosting
When this symbol is lit, the outdoor unit is in defrosting mode. This
is an automatic process to remove the ice from the evaporator. It
takes about 17 minutes and the heat pump will resume working
afterwards. Depending on the ambient temperature and humidity this could
occur several times.
