Once the emergency stop input signal is turned on, all air conditioners stop and do not
restart until the emergency stop input is cleared. When the manual reset is specified for
the resetting method, you need to clear the emergency stop using the intelligent Touch
Manager.
2.6 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, you can add 64 indoor unit groups 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 the operation during power-off conditions. Not doing so
may cause an electric shock.
• Do not clamp high-current cables together with low-current cables.
