Operate the inverter in the open phase operation with the conditions including the preheating
command from the indoor, the outdoor air temperature and discharge pipe temperature.
Detail
Preheating ON Condition
When outdoor air temperature and discharge pipe temperature are below 51ºF, inverter in open
phase operation starts.
