The present invention relates to a porous toner particle with encapsulated metallic flakes. The thermal bypass valve is located in the header and is configured to restrict the flow of fluid through the cooling tubes of the heat exchanger below a target fluid temperature. The interference signal is modulated using P MCSs, where P is an integer greater than or equal to 1. Each rule includes one or more of the actions, and at least one of the rules includes multiple actions and a guard condition for enabling and disabling some of these actions.
