7. MAINTENANCE 7-1 Changing Address of Remote Control Unit in Indoor Unit If you are installing more than 1 indoor unit (up to 2) in the same room, it is necessary for you to assign each unit its own address, so each can be operated by its own separate remote control unit. You assign the addresses by matching the remocon address on the PCB of each indoor unit with the switch positions of its remote control unit. - Page 32 R.D. 28 Reyrieux BP 131 - 01601 Trévoux CEDEX France Tél. 04.74.00.92.92 - Fax 04.74.00.42.00 R.C.S.
