1. For use with an ice-making apparatus having at least one icing site for forming ice and a closed loop water circulating unit for circulating a flow of water to the at least one icing site of the apparatus, a method for electronically controlling the location of the formation of ice, the method comprising:

  • starting the flow of water through the closed loop water circulating unit to the at least one icing site;

    cooling the water at the at least one icing site as it flows through the closed loop water circulating unit;

    sensing a temperature of the water as it circulates through the closed loop water circulating unit;

    comparing the sensed temperature to a first predetermined temperature threshold;

    if the sensed temperature is below the first predetermined temperature threshold, generating a signal;

    stopping the flow of water to the at least one icing site upon receipt of the signal, to generate an ice seed at said at least one icing site;

    restarting the flow of water to the at least one icing site to form ice at the at least one icing site;

    sensing a parameter related to completion of ice making, andinitiating a harvest cycle in response to sensing said parameter.
