Abstract
Improved timing circuits (205), charge dispensing circuits (213,215), and methods and systems (100) for operation of warewashing equipment. According to one aspect of the invention the system operates on both door and conveyor types of machines. The system dispenses both an initial charge amount and a dose amount during normal operations. In door types of systems, only a single power/signal connection (109) needs to be made to the dispensing system; in one embodiment the warewash rinse power connection. Further, the system can dispense detergent at an interval of greater than once per cycle or operation.
