Abstract:
A control for operating a beverage dispensing machine, the beverage dispensing machine having a refrigeration system including a compressor for cooling an evaporator positioned in a water bath for forming an ice bank thereon, the control comprising:a voltage sensing circuit for determining the voltage of an incoming line providing power to the compressor, an ice bank sensing system including conductivity probes positioned within the water bath and a conductivity sensing circuit for determining the conductivity between the probes and the compressor operated to provide for cooling of the evaporator for forming ice thereon when the voltage sensing circuit determines that the incoming line voltage is within design limits of the compressor, and when the ice bank sensing system determines that further formation of ice is required and when a predetermined time delay has timed out since the compressor last operated.
