POSITIONS 4, 5, 6, 7 and 8 RESET THE INDOOR UNIT TO FACTORY DEFAULTS – THESE
RESETS ARE TYPICALLY ONLY USED ONCE

ADJUSTABLE PARAMETERS IN NON-VOLATILE MEMORY IN THE INDOOR UNITS). IF
CHANGES ARE MADE TO THE CONFIGURATION PARAMETERS AND THE USER DOES NOT
WANT THESE TO CHANGE WHEN A UNIT IS RESET, THE INDOOR UNIT CAN BE POWER-
CYCLED OR POSITION ‘3’ MUST BE USED E.G. THIS TECHNIQUE IS USED IF THE IP
ADDRESSES ASSOCIATED WITH THE NETWORK INTERFACES ARE ADJUSTED – THE

BLANK – THEN, START AGAIN (OPTION AVAILABLE WITH RELEASE 2+ OF IU FIRMWARE).
