When receiving the signal for defrosting completion, the opening of the heating thermo-ON indoor unit is 240P for 500P-
Opening EEV and 960P for 2000P-EEV. It will remain like this for three minutes, and then go to normal control.
The thermo-OFF or fan mode indoor unit will recover standby or fan mode control after defrost completion.
