摘要
A closed loop controller and method of operation are provided which allow for configuring the controller with two switches. In one mode of operation, the two switches (22) and (24) are manipulated to increase and decrease the integral time value and the proportional gain, respectively, of the controller (10). In another mode of operation, the first switch (22) is manipulated to select among a plurality of configuration parameters and the second switch (24) is manipulated to select the desired value of the selected parameter. Level shifting circuitry (14) is also provided to permit remote operation of the controller (10) using a modem.
