Thermal system control for a vehicle

A thermal control system comprising:

• a plurality of thermal components including a first respective component and a second respective component, the first respective component being selectively operable as a thermal source;
• a plurality of coolant conduits fluidly coupling the plurality of thermal components to define a coolant circuit;
• a coolant disposed in the plurality of coolant conduits;
• a pump operable to circulate the coolant among the plurality of coolant conduits, wherein within the coolant circuit the first component is upstream of the second component and the pump is upstream of the first component;
• and
• a controller configured to selectively operate according to a circuit heating mode and a local heating mode, wherein in the circuit heating mode the controller controls the pump at a first speed and controls the first respective component as a thermal source and wherein in 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 being less than the first speed, and wherein the controller is configured to operate according to the local heating mode in response to a heating request associated with the second respective component.
