Silent Mode Operation
Silent mode operation is that the unit works at reduced capacity so that the noise produced by the
unit drops. 
This implies that the heating and cooling capacity will also drop. Beware of this when a
certain level of heating or cooling is required.
Silent mode operation may not work while  the product is proceeding higher priority
operation such as defrost operation, anti-freezing operation, and etc.
(When this mode is not operated by the priority order, ONLY display   .)
