•
In case of a central control, operation ON/OFF can be done separately by each zone. (In this case, zone
interlocked setting must be kept as the factory setting (17.08.01).)
•
Structure without a remote controller cannot be accepted because the remote controller group is
controlled within a VKM-GA(M) model. (i-Touch controller, central remote controller)
