22. DEFROST OPERATION CONTROL
01-17
1. CONDITION OF STARTING THE DEFROST OPERATION
The defrost operation starts when the outdoor heat exchanger temperature sensor (Tn) detects
the temperature lower than the values shown in Table22.
2. CONDITION OF THE DEFROST OPERATION COMPLETION
Defrost operation is released when the conditions become as shown in Table 23.
( Table 23 : Defrost Release Condition )
Release Condition
Outdoor heat exchanger temperature sensor value is higher than +16°C.
or Compressor operation time has passed 15 minutes.
