Abstract:
1. A thermal system comprising: a plurality of thermal elements; a control system having a plurality of nodes, the control system having at least one switching device in communication with the plurality of nodes, the at least one switching device configured to selectively apply power to at least one of the nodes and a return to another of the at least one of the nodes; wherein each thermal element is connected between the plurality of nodes and the control system is configured to provide power to at least one of the nodes via the at least one switching device and a return to another of the nodes via the at least one switching device; the control system being configured to calculate a time period for each mode of a plurality of modes, wherein each mode of the plurality of modes represents a different combination of at least one node of the plurality of nodes being provided power and/or return via the at least one switching device, index through each mode by providing power to at least one of the nodes via the at least one switching device and a return to another of the at least one of the nodes via the at least one switching device for the corresponding time period to provide power to the plurality of thermal elements according to the mode.
