Attentions: The water temp sensor (CN9) and indoor
temp sensor (CN24) are unuseful now. The fourth bit
of 4 position dial switch is used to choose the
different speed of indoor fan under heating mode.
"ON" means that the speed of indoor can be choosed
from middle and low."OFF" means that the speed of
