  • Patent number: 7572080
    Abstract: A control system for heating a screed assembly of a paving machine is provided. The control system includes a plurality of resistive heating elements positioned adjacent to a screed plate of the screed assembly. An electrical power supply is selectively connected with the resistive heating elements via switches operated by a controller. The controller is responsive to inputs from at least manual switches and temperature sensors. The controller is configured to automatically adjust the temperature of the screed plate by selectively energizing fewer than all of the resistive heating elements at a time.
