position<br />
This function controls the air direction of the indoor unit.<br />
• The position is automatically controlled according to the operation mode (COOL/HEAT).<br />
• The set louver position is stored in memory by the microcomputer, and the louver returns to the<br />
stored position when the next operation is performed. (Cooling/heating memory position)<br />
The angle of the louver is indicated as the horizontal angle is 0°.<br />
When the louver closes fully, it directs approx. 49° upward.<br />
