WATER PAN CLOSES/FREEZE: When the water pan closes and the hall IC turns on the water valve opens to supply ice making water for a specific time. The supply time varies between startup, reset, and end of bin control cycle between partial flush and full drain.

NOTE Full drain flush: After a freeze cycle ends the unit drains all remaining water out of the tank and refills for the next freeze cycle.

Partial drain flush: (default setting) After a freeze cycle ends, the unit leaves remaining water in tank and adds water for the next cycle.

After water has been supplied the pump motor starts, after 30 seconds the thermistor senses the temperature that will be added with a predetermined offset value and used as the water temperature for the freeze cycle, pan opening, defrost, and pan closing cycle. The freeze cycle is considered to be 100% complete when the predetermined target and the integrated values are reached. To reduce ice forming on the water pan when the freeze completion rate reaches 100% with an ambient temperature below 86º F (30ºC), the hot gas valve opens and closes two times to raise the water pan temperature and the actuator motor starts to open the water pan. The freeze cycle is not considered complete and the pump motor and fan motor continue. The unit will continue to cycle between freeze and harvest until the bin control opens, signaling a full bin or until power is interrupted
