1. General This booklet briefly outlines where and how to install the system controller. Please read over the entire set of instructions for the indoor and outdoor units and make sure all accessory parts listed are with the controller before beginning. NOTE Give these instructions to the customer after finishing the installation. Part Name Figure Q’ty System Controller 1 Rubber bushing (7/8 in.) 4 Screws for fixture (1-3/16 in.
Installation procedure (1) Remove the flat-top screw on the bottom of the back case. When you open up the decorative cover, you will see two notches under the controller. Inset a coin or other flat object into these notches and pry off the back case. (Fig.1) (2) Connect the wires to terminal base of the system controller (see next page). (3) Attach the back case with the 2 screws (1-3/16 in.) provided.

5. Mode setting According to function of each system controller, set SW1 as Fig. 7. (1) Central control/Remote control mode Central control mode System controller is used as central control equipment. Individual setting by remote controller can be inhibitted by system controller. Remote control mode System controller is used as remote controller. Setting by system controller is inhibitted by other central control equipments. (2) ALL/ZONE mode ALL mode All indoor units can be controlled by system controller.
6. How to perform zone registration To operate the system controller properly, zone registration is required after finishing the test run (and after setting all indoor unit addresses) using one of the following methods.
ZONE registration table ZONE 1 2 GROUP Central address 1 Indoor unit address (UNIT No.
(a) Zone registration using the remote controller (Determination of central address) In this case, after confirming which indoor unit is connected to the remote controller and that the air conditioner in the OFF state, you set the central addresses one at a time. If the system has no remote controller, connect a remote controller to the system temporarily. Then follow this procedure. NOTE The indoor unit address must already have been set before performing zone registration.
(b) Zone registration using the system controller In this case, you set all Central addresses by system controller at once manually. and buttons at the same time (1) Press the for more than 4 seconds. and CODE No. C1 will flash. (2) After confirming that CODE No. C1 is displayed, button. Once in this mode, a change press the takes place as Fig. 10. (3) Select the zone and group No. which you want to set with and (GROUP) buttons. buttons. If already set, press the (4) Set the unit No.
(c) Automatic zone registration using the system controller and buttons at the same time for more than 4 (1) Press the seconds. and CODE No. C1 will flash. and ( ) button and (2) Select CODE. No. C2 by pressing press the button. C2 changes from flashing to ON state and automatic zone registration will start. (3) Registered GROUP No. will be disappeared all. (4) Central address will be assigned from small indoor unit address to large one in numerical order automatically.
7. How to check overlapping of central address no. (1) Press the and buttons at the same time for more than 4 seconds. and CODE No. C1 will flash. (2) Select CODE. No. C3 by pressing , ( ) button and press the button. C3 changes from flashing to ON state and will flash. Then auto. overlap checking will start. (3) If C3 changes from ON to flashing and stops flashing and disappears, there is no overlapping. Then finally, complete the auto overlap checking mode by pressing the button. (4) If some of GROUP No.
8. Memory back up switch ON OFF Check the back up switch is ON for back side of system controller PCB. Back up switch Back up battery 9. Test run (1) Power on for all indoor units. Next, power on for system controller. will flash, checking the indoor unit address automatically. (2) If group No. displayed on system controller is not same as indoor unit No.* which is connected, see Fig. 7 and setting again. *In case of group control, main unit No. only. 18 CZ-64ESMC1U_eng.
