Abstract
The temperature controller employs a single thermistor temperature sensor providing an analog signal indicative of engine system temperature. The analog signal is compared with a plurality of separate threshold temperatures to produce a multiplicity of separate temperature signals representing different temperature ranges across the operating temperature spectrum of the engine system. These separate temperature signals are processed through digital logic gating circuitry to provide sequentially occurring outputs on parallel output leads. The sequentially occurring outputs sequentially activate different heat dissipating mechanisms within the engine system to maintain a substantially constant temperature.
