During the following procedure, NEVER PUSH the ON/OFF (Enable operation) Button on the zone controller.

For Indoor Units That Are NOT Being Controlled as a Group

1. Verify the zone controller cable is plugged into CN-REMO socket on the indoor unit PCB.
2. Using the controller, go to the setup function 02 (icons are different for each controller. Refer to the controller user’s manual for more

information.)

3. Type in the Hex Central Control address that has been designated to the unit.
4. Repeat Steps 1 through 3 for each indoor unit in the building.

For Indoor Units That Are Being Controlled as a Group

1. Before attempting to assign a central control address to an indoor unit controlled as a group, identify which unit in the group will be identi-

fied as the Master indoor unit and which indoor units are going to be identified as Slave units.

2. Go to the Master indoor unit, and access the PCB.
3. Verify a group control pigtail cable is plugged into the CN-REMO socket on the indoor unit PCB. If it is not, do so now by plugging the

communications cable pigtail into the CN-REMO socket.

4.  If the group control extension cable between the indoor units is plugged into the Y-cable, unplug the extension cable from the Y-cable.
5.  If not already present, plug the zone controller communications cable into the pigtail cable.
6.  Using the controller, go to the setup function 02 (icons are different for each controller. Refer to the controller user’s manual for more

information.) Type in the Central Control address designated for the Master indoor unit.

7. Disable power to the Master indoor unit. Do not restore Power to the Master indoor unit at this time. It shall be restored in step 18.
8. If the zone controller and associated communications cable has already been permanently mounted in place, plug the Y-cable back into

the pigtail and obtain a loose zone controller with a communications cable to continue programming the Slave indoor units.

9. Go to the first Slave indoor unit and disconnect the Y-cable from the pigtail.
10. Plug the zone controller communications cable into the socket on the pigtail cable. Do not push the ON / OFF button or enable indoor unit

operation.

11. Using the controller, go to the setup function 02 (icons are different for each controller. Refer to the controller user’s manual for more

information.) Type in the Hex address assigned to the unit.

12. Change DIP switch No. 3 on the indoor unit PCB to the “ON” position.
13. Disable power to the indoor unit using the disconnect switch. Wait one (1) minute.
14. While power is off, unplug the zone controller cable from the pigtail socket.
15. Plug the group control Y-cable back into the pigtail.
16. Restore power to that Slave indoor unit, and go to the next Slave indoor unit.
17. Repeat Steps 9 to 16 for each Slave indoor unit except the last one in the group. At the last Slave indoor unit, the process is the same

except unplug the group control cable from socket CN-REMO on the indoor unit PCB board and plug the zone controller cable into the

same socket.

18. After all Slave indoor unit have addresses assigned, go back to the Master indoor unit and restore power.
