Quiet Night™/Sleep cycle
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 .
Self-flushing
At the completion of the 20 minute time delay, the machine checks for a cumulative one hour of ice making time
since the last off-cycle flush . If the cumulative ice making time exceeds one hour, the machine will energize the
drain valve P19 for 60 seconds to drain the evaporator . It will then refill with water, flush again, refill and begin
making ice if the
LOW BIN LED is on . If the ice making time is less than 1 hour, the machine will start and begin
making ice without draining the evaporator .
