摘要： A controller for a heating system (1) of a paving screed (2) i ncluding a screed plate (3). The heating system (1) is connected with the screed (2) and configured to transfer thermal energy to the screed plate (3) and includes an actuator (16) configured to adjust thermal energy output of the heating system (1). The controller includes a temperature sensor (12) connectable with the screed (2) and configured to sense temperature of the screed plate (3). The sensor (12) is also configured to generate electrical signals proportional to sensed temperature. An electrical logic circuit (14) is electrically connected with the sensor (12) and is electrically connectable with the actuator (16). The logic circuit (14) is configured to compare a temperature signal from the sensor (12) with a desired temperature value and to automatically operate the actuator (16) such that the actuator (16) adjusts thermal energy output of the heating system (1) so as to maintain screed temperature about the desired temperature value. Preferably, the logic circuit (14) is a microprocessor and the temperature sensor (12) is a thermocouple.
