• Adjust the address of digital switch of transmitter mounted. (Adjust the address of transmitter
mounted in chamber “A” to “0” and “B” to “1”... continue the adjustment up to “F” to “F”)
• Connect the terminals O1 and O2 of the terminal board mounted on the centralized controller to the O1
and O2 of the terminal board installed in chamber “A”.
• If the wired remote controller is installed, be sure to put off the SW2(DS01) of PCB option switch.
• Remove the centralized controllers installed at chamber “B” to chamber “F” if any except the A
chamber.
• Adjust the address of digital switch of indoor unit PCB to “0”.
• Connect O1 and 02 of terminal board installed in chamber A to O1 and 02 of terminal board installed in
chamber B.
• Continue to connect O1 and 02 of terminal board mounted on indoor unit in chamber B ~ F to O1 and
O2 of terminal board of centralized controller(recommended).
2. Setting at centralized control side

Caution :
• The communication between centralized controller and transmitter is modem method and there is no polarity but connect “O1”
terminal to “O1” terminal and “O2” terminal to “O2”terminal.
• The address of transmitter mounted on each indoor unit shall not be duplicated.
• After the resetting of operation level of centralized controller, it is not necessary to reset the power differently from that of wired
remote controller. In other words, the operation level can be reset even during the operation if required.
