Touch Controller is for exclusive use as a Main system Controller and cannot be used as a Sub system controller. The system cannot
be configured as shown in the examples below.
Note
►Groups
that are not controlled by a main controller cannot be
controlled from a sub controller.

►Each group cannot be controlled by two or more main
controllers.
►Sub controllers cannot be controlled by two or more main controllers.
*Exception:
Although AG-150A series and TC-24A are both designed for use as the main system controllers, they can be used in combination
with each other. When using them in combination, make the group settings from both controllers. Enter the address from each
controller in the field for registering the address of the system controller in each group.
Address setting
Assign the lowest address to the main indoor unit in the group, and assign sequential addresses
to the rest of the indoor units in the same group.
Note: The following models require two addresses: PEFY-AF1200CFM and PEFY-AF1200CFM-R
Assign an address that equals the lowest indoor unit address in the same refrigerant system plus
50.
Assign an address that equals the address of the outdoor unit in the same refrigerant system
plus 1.
Assign an arbitrary but unused address to each Lossnay unit after assigning an address to all
indoor units.
Same rules as for the indoor units apply. An M-NET adapter (sold separately) is required.
Same rules as for the indoor units apply. An M-NET interface (sold separately) is required.
Assign an address that equals the address of the main indoor unit with the lowest address in the
group plus 100. Add 150 instead of 100 to set a sub-remote controller.
Assign an address that equals the lowest number of the group to be controlled plus 200.
Assign an arbitrary but unused address to the controller after completing the address setting for the units
with an address between 1 and 50. The number of controllable units depends on the number of channels
used. (1 channel = I unit)
Address setting is not required. The connection of two remote controllers requires the main/sub setting
for each controller to be made.
