3 minutes when the Operation Switch at the Remote Control or Main Unit (Touch Control Panel) is turned ON.
 
    • 
• •  • W hen the setting temperature is reached during cooling operation, the compressor stops and it will not start for 3 minutes.
 
    • 
• •  • Protection of compressor to balanc e the pressure in the refrigerationcycle for 3 minutes.
9.2.2. 7 minutes Time Saved Control
 
    • 
• •  • The compressor will start automatically if it has stopped for 7 minutes even if the room temperature is between the compressor
ON temperature and OFF temperature.
9.2.3. Starting Current Control
