Patent ID: 8568058

Claim:
A heating control system for a screed, the screed including a plurality of screed plates including first and second screed plates, and a plurality of temperature sensors, each temperature sensor coupled to one of the plurality of screed plates, the heating control system comprising: a controller; the first screed plate coupled to a first temperature sensor and at least one first heating element, the first temperature sensor and at least one first heating element being linked to the controller, the at least one first heating element heating the first screed plate under control of the controller and according to a first algorithm; and the second screed plate coupled to a second temperature sensor and at least one second heating element, the second temperature sensor and at least one second heating element being linked to the controller, the at least one second heating element heating the second screed plate under control of the controller and according to a second algorithm; wherein if the first temperature sensor fails, the controller selects a sensor signal corresponding to another temperature sensor operating with a similar heating algorithm as the failed first temperature sensor and the controller uses data from the another temperature sensor to operate the at least one first heating element according to the similar heating algorithm.
