A pre-wet feature provides for engagement of the water pump for a period of time following turn on of the evaporative cooler to permit the cooler pads to become wet before the blower fan is engaged. A plurality of diagnostic visual indicators are provided to allow the user to quickly recognize faults that may occur in various components of the controller.
