The processor is configured to monitor cooling fluid in the cooling system and cause the system to drain fluid when an amount of dissolved solid in the fluid exceeds a predetermined threshold. The plurality of relays are configured for both wet operation and dry operation. The controller is accessed using a web server on the controller through a communication port. The controller is controller and control parameters are modified via the web server. A relay of the plurality of relays in the controller is configured for either wet operation or dry operation.
