Heating control system for a screed
CAFCFirst Claim
1. A heating control system for heating a single screed plate selected from among a plurality of screed plates included on a paving machine screed, comprising:
- a first heating element operatively positioned with respect to the single screed plate;
a second heating element operatively positioned with respect to the same single screed plate as the first heating element, the first and second heating elements both being configured to appy heat to the single screed plate; and
a controller configured to selectively energize the first heating element and the second heating element such that there is at least some period of time when heat is applied to the single screed plate from only one of the first heating element and the second heating element.

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.
