1. Hold the front/rear central part of the central controller with the both hands and then separate the case by pulling it ahead or behind while lightly pressing the front case. 2. Loose 4 screws anchoring PCB and then separate the rear case and PCB. 3. Anchor the rear case on the installation surface at holes using anchor screws and then join the rear case and PCBs. Method of Installation Hole for anchoring CAUTION: 1. Install the product on flat surface and install anchoring screws at more than 2 places. Otherwise the central controller may not be anchored properly. 2. Do not tighten anchoring screws too tightly. It may cause deformation of the case. 3. Do not deform the case at random. It may cause malfunction of the central controller.

Method of Installation 4. Connect connection wires according to the instructions (See page 12) • To take out connecting wires from back side of case, use the wire hole on the rear case. • To take out connecting wires from front sides of case, puncture the dotted spots as shown in the picture and take out the connecting wires out fo it. 5. Perform the switch setting according to switch setting method. (See page 11) 6. Properly push and insert the front case into the rear case. 7. Check operation after applying power.

installed on the outdoor unit and central controller. 2. To supply power to the central controller, supply it from the terminal block Vcc and GND terminal of PI 485 or supply it through a separate DC 10V power supply unit. • Where more than 2 central controllers are installed, refer to system wiring drawing. (See page 6) Method to Connect Wires ON L1 2 3 4 KSDO4H Central controller Central controller PI 485 10V VCC GND GND BUS-A C BUS-B D Outdoor unit (PI 485) Method to Connect Wires CAUTION: 1. For supplying DC10V power from PI 485, power supply is permitted up to 3 central controllers per PI 485. When supplying power to more than 3 central controllers, failure may occur in operation of the central controller. 2. For expanding and connecting PI 485 communication lines C, D up to 16 central controllers can be connected. (In case if functional controller is also connected, then only 8 controllers can be connected.) 3. Use the 0.75 Square Shield wires for connection wires between PI485 and central controller wires. 4. For length of connection wires, observe the following regulations. - Length of connection wires between central controllers: Less than 1m - Length of connection wires between outdoor unit and central controller: Less than 200m - Length of whole connection wires: Less than 1Km.

For setting of Group/Master, use precise driver [(-) 20mm(W)] and set applied weight to 198N (2kg) or less. When applying unreasonable force, PCB and switch may be damaged due to shock. 2. Do not set more than 2 Masters. Where multiple of Master is set, communication with the outdoor unit is not done and thus it becomes impossible to control the indoor unit. 3. Always initialize power after setting the switches. If power is not initialized, it becomes impossible to recognize the settings of group and master/slave.

When communicating with the product using LGAP, turn on the dip switch no. 2. - The master/slave setting is applied by turn on/off the dip switch no.1. - When installing in connection to the PC/advanced central controller with LGAP applied, simple central controller must be set with the dip switch as slave control with LGAP application. * When installing a simple central controller with LGAP, the dip switch No. 4 of PI-485 must be turn on for normal operation(refer to 14 page). * When using only the simple central controller, it is possible to either apply the LGAP or not apply the LGAP. But the LGAP setting of PI-485 and that of the simple central controller must be the same. * Refer to the PC/advanced central controller manual on how to apply the LGAP for PC/advanced central controller.

Now the system is ready for address checking. 2) Press ON/OFF key once toward the Indoor unit which shows set address on the display.(The address displaying time and its way can depend upon the type of Indoor unit ) 3) Reset the remote controller to use it for normal operation mode. C Some remote controllers may not support above functions according to the production date of wired/wireless remote controllers. As it has no concern with customer's use, use the remote controller available for the address setting during installation. C The remote controller having this function will be given with the purchase of central controller.

Troubleshooting Troubleshooting 1. Cross check again, if all connection are made as per instructions given in the installation manual. 2. In case, if multi products (Multi-V, MPS, Multi etc.) are connected to the controller (to one network), first finish the settings for all products & only then start the system. 3. Dip switch setting of PI 485 pcb as per the product type & the group no. mismatch between controller & its respective indoor units are the most common mistake usually happen. 4. Group no. set at rotary switch of SCC connected to outdooor unit must exactly match with all indoor units connected. Incase any indoor units have same address settings, the system will not take them into its network. 5. Turn on the system & give sufficient time to the system to check the whole network connectivity. In some cases, it takes time to show all indoor units connected on the controller. Also the display can be random. 6. Using PI 485 pcb also, we can check if no. of indoor units connected matches exactly with no. of indoor units installed. Press the refresh button on PI 485. A little later, its red LED (LED01G) would blink no. of times equal to no. of indoor units installed. If the numbers doesn't match, check again the address settings of all indoor units. 7. Never ever change the settings while the system is running. Stop the system & then make the required settings. 8. For new settings to take place, sometimes, it is advisable to turn off indoor units and then the main power. After a short while, restart the system. (This is not a fixed guideline but be considered case by case)
