Address Switches - Sanyo C0951 Technical & Service Manual

7-3. Address Switches

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
remote control unit. You assign the addresses by
matching the switch positions of each indoor unit with
the switch positions of its remote control unit. The
switches of the remote control unit are shown in Fig. 8.
For instance, to set up 2 indoor units, switch Unit A's
address switches. Then switch Unit B's address switch-
es. It is important that you match the switches of the air
conditioner unit with the switches of its remote control
unit.

NOTE
An indoor unit cannot be remote controlled if its remote
control unit is too far away (more than 26 ft.). If the
remote control unit does not seem to work correctly,
bring it closer to the unit being operated and try again.
For this reason, if the remote control unit is to be used
from a fixed position, operation should be checked at
that position before mounting.
