9-6. AUTO VANE OPERATION 1. Horizontal vane (1) Vane motor drive These models are equipped with a stepping motor for the horizontal vane. The rotating direction, speed, and angle of the motor are controlled by pulse signals (approximately 12 V) transmitted from indoor microprocessor. (2) The horizontal vane angle and mode change as follows by pressing VANE CONTROL button.
(11) LONG MODE ( ) (MSZ-GE60/71/80) By pressing LONG button indoor fan speed becomes faster than setting fan speed on the remote controller, and the horizontal vane moves to the position for LONG mode. The remote controller displays “ ”. LONG mode is can- celled when LONG button is pressed once again or VANE CONTROL button is pressed or ECONO COOL button is pressed in COOL mode.
PROGRAM TIMER • OFF timer and ON timer can be used in combination. The timer of the set time that is reached first will operate first. • “ / ” and “ / ” display shows the order of OFF timer and ON timer operation. (Example 1) The current time is 8:00 PM.
