Abstract
A thermal control system includes first and second components. A plurality of coolant conduits fluidly couple the components to define a coolant circuit. A pump is operable to circulate coolant among the conduits. Within the coolant circuit, the first component is upstream of the second component and the pump is upstream of the first component. A controller is configured to selectively operate according to a circuit heating mode, wherein the controller controls the pump at a first speed and controls the first respective component as a thermal source, and a local heating mode, wherein the local heating mode the control controls the pump at a second speed and controls the first respective component as a thermal source. The second speed is less than the first speed. The controller operates in the local heating mode in response to a heating request associated with the second respective component.
