    1 Installation and Commissioning For Touch Screen: In this section, it is explained about how to install the hardware of CCM-270A/WS in the wall and also what are the various connections that are required to be done between the centralized controller and the VRF units to use the centralized controller to control the units.
  • Page 20 CCM-270A/WS 1.1.2 Install the Metal Parts Make sure that the hooks of the metal parts face upwards. Use 4 screws ④ provided as accessories to secure on the installation base. Note: Make sure that appropriate force is exerted to secure the metal parts with the screws. Excessive force may lead to deformation of the four screw holes for the metal parts, which would make it hard to mount the metal mounting board.
  • Page 21 CCM-270A/WS 1.1.3 Install CCM-270A/WS Once the connections are done, place the main unit vertically into the installation base. A magnetic force would attract the controller. Exert downward force to mount the controller on the metal part. There are hooks which are attached on the installation base and the controller can be mounted on these hooks.

  • Page 22: Topology Modes

    1.2.1 Auto Topology Mode This is the basic mode of connection while using the CCM-270A/WS centralized controller. This type of topology does not require the user to upload any topology file. The user simply needs to connect the units with the controller and on searching the information about the air conditioning units through the “Install”...
  • Page 23 In case of using the manual topology mode, we need to supply the complete information about the connections between the ODU and IDU to the CCM-270A/WS in the form of a topology document. This document can be uploaded into the controller with the help of the USB disk.
  • Page 24 The imported system bus exceeds limit. Please CCM-270A/WS port is not within 0-5. confirm it before search The imported refrigerant system exceeds limit. Refrigerant system address is not within 0-7.

  • Page 25: Flow Chart

    Before we discuss in detail about the various steps that need to be followed for successful installation and commissioning of CCM-270A/WS device, below is listed a flow chart of all the events that need to be followed. In this flow chart, is given a sequence of actions that need to be followed to successfully finish the installation and commissioning of the CCM-270A/WS gateway device both for touch screen and computer website.
  • Page 26 CCM-270A/WS 1.3.2 For Computer Website The following flow chart describes the installation steps required while we need to use only the computer website of CCM-270A/WS. Connections between ODU &IDU Power cable connection LAN/Network connections Pre Installation(IP) Settings Set the ODU to auto addressing mode & adjust ENC4 switch* Open the website;...

  • Page 27: Connections Between Odu And Idu

    1.5 Power Cable Connections We need to make sure that the power supply has been provided to the CCM-270A/WS. If the power supply is not there we cannot perform the further operations such as searching the units. The power cable is not provided as a standard accessory with the box.

  • Page 29: Network Connections

    CCM-270A/WS For Power Indication: Look at the back side of the CCM-270A/WS gateway device and check whether the red colored system lightings are blinking inside the back panel of the device. If the LEDs are blinking, it means power is being received by the CCM-270A/WS gateway device.
  • Page 30 CCM-270A/WS Important Points: 1. The default Ethernet IP of the CCM-270A/WS is 192.168.100.40:8000 2. When more than one gateway devices are connected to LAN in a project, configure different IPs for the gateways 3. The centralized controller obtains static IP.

  • Page 31: Pre Installation Settings

    1. Configure Single IP Address: For the CCM-270A/WS gateway, to connect with the computer it needs to be verified that it is in the same IP segment as the computer. To make this happen, we need to make sure that proper IP Configuration settings have been done. Following are the steps that need to be followed to complete the IP settings: Default IP of CCM-270A/WS is 192.168.100.40:8000;...

  • Page 33 CCM-270A/WS After you finish this IP configuration, try to visit the website of the CCM-270A/WS by typing the IP address (192.168.100.40:8000) in any of the web browser (preferably Google Chrome version 52.0 or above) if the website of CCM-270A/WS is getting opened, it means that the IP configuration setting is successful.
  • Page 34 CCM-270A/WS Enter "ipconfig" above to display the local dynamic IP address. Use this address as the IP address in TCP/IP properties to complete the static IP address configuration. Consult the local network administrator for details. Once the static IP address has been configured, open the Internet Protocol TCP/IP Settings page again. Select "Advanced..." to go to the TCP/IP advanced settings page, as shown in the figure below.
  • Page 35 3. Local LAN Access: As long as the computer or other similar equipment in the LAN is in the same segment as the CCM-270A/WS, you can use the address bar in the browser on its operating system to enter the address to link to the webpage of the CCM-270A/WS (for example: http://192.168.100.40:8000) to directly access, operate and control the air conditioners.

  • Page 36: Auto Addressing Mode

    Let’s discuss the settings for this switch. In case, there is only one system in each port of CCM-270A/WS, there is no need to set the ENC4 switch for this situation. We can keep the network address of the outdoor unit as 0 as the outdoor units would be distinguished from each other on the basis of settings of ENC1 switch.

  • Page 37: Booting Up Of Ccm-270A/Ws

    3. If the equipment does not get started after some time, you need to check the red colored system lightings inside the back panel of the CCM-270A/WS are blinking or not. If not, it means that the equipment is not energized. Check the power supply and wiring.
