Abstract
An electronic climate control system for an automotive vehicle comprises a by-pass passage for delivering cool air flowing through an evaporator core directly to discharged-air ventilators, a by-pass door provided at a communication inlet of the by-pass passage for adjusting a flow rate of cool air through the by-pass passage, a hot-water valve provided for adjusting a flow rate of hot coolant to a heater core, and an actuator being common to the by-pass door and the hot-water valve for adjusting a bypass-door opening and a water-valve opening. The actuator acts to fully close the water valve when the by-pass door is fully opened. Also provided are a climate control panel for selecting one of discharged-air outlet modes, a by-pass PBR for monitoring the bypass-door opening, and a control unit for limiting the bypass-door opening to a value less than a maximum opening equivalent to a full-open position of the by-pass door when a predetermined discharged-air outlet mode except VENT mode is selected by the control panel.
