Control Assembly: Description and Operation
With the Ignition Switch in "RUN," voltage is applied through the IGN Fuse to the Heater Control Assembly. The operating mode of the system is determined by push button switches on the front panel. Voltages from the Heater Control Assembly determine which
air valves are to be operated as well as the position of the Air Temp Valve.
