Connecting iTM plus adaptors
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 Man-
ager 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. Doing so
may cause an electric shock.
•
Do not clamp the cables with high-current lines such as a power cable.
