CONSTITUTION:When a switch 2 is turned ON with a lever 11f of an air amount setting switch 11 at a low speed position 11c, a transistor 7 activates a relay 8 closing its contacts 8c, 8e, 8g, activating a blower 9 at low speed. An electromagnetic valve 14 connects 14b, 14c and an electromagnetic valves 13, 15 connect ports 13a, 15a and vacuum actuators 30, 31. Switching dumper 32 of inside and outside air and a passage switching dumper 19 of heating part 17 are at the position shown by solid lines.
