(Protection of compressor)
• 5sec… Vertical air flow direction control louvers open in 5 seconds to prevent noise between louvers and wind.
• 30sec… The 4-way valve is ceased for 30sec. to prevent the refrigerant-gas abnormal noise when the Heating
operation is OFF or switched to the other operation mode while compress is off.
While compressor is running, it takes 3~5 seconds to switch.
