摘要:
A temperature control door (27) controls air flow through a duct (12) and is positioned in accordance with the output of a sensor (41), (42). A slider (74) of a potentiometer (72) is connected to the door (27) so that the slider (74) is in a central position when the temperature control door (27) is in a central position. A switch (86) connects the slider (74) to one end of a resistance element (73) of the potentiometer (72) when the temperature control door (27) is on one side of the central position and the apparatus (11) is in a cooling mode and to the other end of the resistance element (73) of the potentiometer (72) when the temperature control door (27) is on the other side of the central position and the apparatus (11) is in a heating mode. The speed of a blower (16) which forces air through the duct (12) is controlled in accordance with the resistance of the potentiometer (72). A switch (87) controls the blower (16) to run a maximum speed when the apparatus (11) is in a maximum cooling mode.
