---Defrosting Conditions
Starting Of Defrosting Condition (meet one of the following is ok):
(1)Accumulated time when temperature of outdoor heat exchanger coil T3 is below 3°C
reaches to 40 minutes, then consecutive 3 minutes less than -5 degrees (Just for the
AC is turn on , whether or not the heating mode the temperature was detected, start
to statistical time when reach the temperature condition . Shut down or defrosting
calculate time again).
(2) Accumulated time when temperature of outdoor heat exchanger coil T3 is below 3°C
reaches to 60 minutes, then consecutive 3 minutes less than -4 degrees (Just for the
AC is turn on , whether or not the heating mode the temperature was detected, start
to statistical time when reach the temperature condition . Shut down or defrosting
