Instrument Panel Control Assembly

Consists of two units as follows: 1)  Temperature Dial which permits selection of desired in-car temperature (65°F, to 85°F. in 5° graduations) and positions temperature dial rheostat accordingly (see SENSORS & TEMPERATURE DIAL RHEOSTAT above). 2)  Selector Lever which operates the Vacuum Control Valve to "program" the system for desired operation. The vacuum control valve is mounted on the instrument panel control assembly and linked directly to the selector lever (no adjustment required). A 2-stage DC amplifier provides a voltage output proportional to the input signal from the sensors to control the transducer.

NOTE: The In-car sensor is included on the instrument panel control assembly.
