Only the addresses are preset before shipment (All other switches are set to OFF.) Unless otherwise specified, leave the
switch to OFF where indicated by "-," which may be set to OFF for a reason.
To set the address of the models equipped with a single fan, set only SW1-3 to ON (= address 5). For the models equipped
with two fans, set SW1-3 to ON (= address 5) on the fan board on the right when seen from the front of the control box, and
set SW1-4 to ON (= address 6) on the fan board on the left.
Leave SW1-1 to OFF during normal operation. Setting this switch to ON will disable the error detection function and may result
in equipment damage.
