A thermal system includes a thermal control unit adapted to supply temperature controlled fluid to one or more thermal pads. The thermal pads may include an interior chamber for fluid circulation, an inlet and an outlet, and first and second temperature sensors positioned adjacent the inlet and outlet, respectively. Some pads include a valve adapted to control an amount of fluid flowing through one or more channels within the pad. The thermal control unit may include a controller that controls the fluid temperature based upon temperature readings from first and second temperature sensors positioned remotely from the thermal control unit. The thermal control unit may also include a valve that selectively controls the amount of fluid exiting the thermal control from one or more outlets based upon one or more temperature readings. The system may include one or more thermocouples with conductors placed on or in the thermal pads.
