Reverse-Cycle Defrosting
Frost sensing
• The temperature of the heat exchanger remains at or below the L1 line for 3 minutes after the start of HEAT operation.
• The temperature of the heat exchanger remains at or below the L2 line for 120 minutes after the start of HEAT operation.
• Defrosting is carried out every 2 hours regardless of above temperature.
Releasing of defrosting
• Outdoor heating exchanger temp. is over 20°C.
• Defrosting operation lasts 12 minutes (maximum).
Non-Stop Defrosting
•Frosting is assumed according to the outdoor temp.,outdoor heat exchanger temp.,and operation time.
Releasing of defrosting
•Outdoor heating exchanger temp. is over 14° C.
•Defrosting operation lasts 12 minutes (maximum)
