3.2.3. Connections
If you have many air conditioners, use iTM plus adaptors to connect them. It is a fact that the number of indoor groups you can control
using a single intelligent Touch Manager is limited to 64. By using iTM plus adaptors, however, you can connect additional 64 groups of
indoor units per iTM plus adaptor. Moreover, considering that the intelligent Touch Manager can be connected with a maximum of seven
iTM plus adaptors, you can control a total of 512 groups of indoor units at a maximum using a single intelligent Touch Manager.
WARNING
• Be sure to perform this procedure with the power supply turned off. Not doing so may cause
an electric shock.
• Do not clamp the cables with high-current lines such as a power cable.
