When the dwell time of 20 minutes has expired, the TIME DELAY LED goes off. If 5 seconds of ice has been
dispensed and the SLEEP CYCLE LED (Symphony Plus only) is off, the ice machine will go through the normal

The board monitors ice dispensing through a line voltage input to P15. If the ice dispense has not be initiated for
more than 5 seconds during the 20 minute time delay, the SLEEP CYCLE LED comes on. The machine will stay
off for 12 hours unless 5 seconds of dispensing is seen. After 12 hours, the SLEEP CYCLE LED goes out and the
ice making will resume if the bin thermostat is closed. The sleep cycle dispense duration is adjustable using the
DIP switches on the control board.
