An optional module allows the user to select the maximum temperature wanted in the dryer cabinet, the minimum temperature needed for effective drying is set at the factory. Control is exercised via a microprocessor over the heater and the fan of a heater/fan unit, a recirculating blower, and the blower of an optional HEPA filter assembly if that assembly is present.
