Sanyo CH0952, CH1852 Finding the Address Switches, Switch Positions for Up to 2 Units

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	Address
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.
