the controller.
A.  REGULAR TIME DEFROST (TIM)
  If controller is preprogrammed for “TIM”, press and 
release the Manual Defrost button until “dEF” appears.
B.  REAL TIME CLOCK (RTC)
  If controller is preprogrammed for “RTC” press the and 
hold the Manual Defrost button for 5 seconds until 
“dh1” appears. Release the Manual Defrost button 
and then press and hold for an additional 5 seconds 
until “dEF” appears.
DEFROST WILL ONLY TERMINATE ONCE A SPECIFIC PRESET 
TEMPERATURE OR A PRESET TIME DURATION IS REACHED.
