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. Also, it is discussed that there are two ways to install the units into the
centralized controller depending up on the type of indoor units and outdoor units combination that is by Auto Topology
mode and Manual Topology mode. This has been discussed in detail below.
For Computer Website: In this section, we will take a look at the various connections and configurations that need to be
done between the CCM-270A/WS & computer to make the CCM-270A/WS and higher devices (in case connected with
IMMPRO) run successfully. Similar to touch screen, there are two ways in which we can install the units in the
CCM-270A/WS website i.e. the Auto Topology and Manual Topology. Here, we will have a look at both these also in
"Topology Modes" section1.2.
