Main check items
(1) Is the relay connector of the header unit connected after address setup?
(2) Is the relay connector of the follower unit removed?
(3) Is the end resistance (SW30-bit 2) of the header unit with the smallest line address
number in the central control turned on? (Setup is unnecessary for follower units.)
(4) Is the terminal resistance (SW30-bit 2) of the header units, except for the line with the
smallest central control line address, turned off? (Setup is unnecessary for follower units.)
(5) Are addresses in the line address (SW13, SW14) not duplicated in each refrigerant line?
