The Wizard 4000 ARC provides chemical usage and feed rate data that the standard Wizard offers, plus the added ability to control the refill of the chemical day tank. Three refill modes are offered: Auto mode requires no operator input, Semi-auto requires an operator to initiate the refill event and Batch mode adds a preset amount of water for diluting powdered chemicals. Monitor and control up to four separate tanks with a single Wizard 4000.
