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- |

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.
