Abstract
An ice bank control system for a beverage dispenser for preventing the unnecessary erosion of the ice bank when the dispenser is idle or inactive, and for thus increasing the draw capacity of the dispenser. The control system includes a pair of ice bank sensors for sensing first and second locations of the surface of the ice bank, the second sensor being spaced further from the cooling coils than is the first sensor. Each sensor generates an electrical signal which, through appropriate electrical control circuitry, controls the on/off mode of the electrical motor that drives the water agitator and also the electrical motor that operates the refrigeration unit.
