The present disclosure is directed toward a control system for controlling a heater that includes at least one heating element. The control system includes a power converter operable to supply an adjustable voltage output to the heater, a sensor circuit that measures an electrical characteristic of the heating element of the heater, a reference temperature sensor that measures a reference temperature of a reference at the heater, and a controller. The controller is configured to calculate a primary temperature of a heater element based on the electrical characteristic and determines the voltage output to be applied to the heater based on at least one of the reference temperature and the primary temperature. The controller is configured to operate in at least one of an operation mode and a learn mode, and execute protection protocols when voltage is being supplied to the heater.
