Abstract
In order to provide a controller which is readily adaptable for use with a plurality of different heaters, an arrangement is provided for storing a plurality of control and regulation programs for the operation of a plurality of different heaters. Based on selection instructions identifying a particular heater, an appropriate control and regulation program can be selected from among said plurality of programs. The controller then provides suitable control and regulation signals to said heater in accordance with the selected program.
Claims16
A controller for controlling the operation of a heater comprising:
- means for storing a plurality of control and regulation programs for the operation of a plurality of different heaters, wherein said storage means includes various preselectable parameters for running of said stored programs;
- means for selecting one of said plurality of control and regulation programs for a particular heater from among said plurality of different heaters in accordance with selection instructions identifying said particular heater;
- means for providing control and regulation signals to said particular heater in accordance with the selected control and regulation program;
- and
- means for receiving distrubance variables indicative of heater operation and environmental conditions pertaining to heater operation;
- wherein said means for providing control and regulation signals includes a programmer for receiving said disturbance variables and providing said control and regulation signals in accordance with said disturbance variables and said selected program, wherein said heater is a vehicle heater and wherein a vehicle supply voltage is input to said programmer as a disturbance variable, said means for providing control and regulation signals providing such signals to preheat said vehicle prior to starting an engine of said vehicle.
A controller for controlling the operation of a heater comprising:
