3 Initial Settings

[Notes on using the TC-24A with the AG-150A controllers*]

In addition to making the group and interlock settings on the TC-24A, the same setting information must be entered on the AG-150A 

controllers. Also, enter the M-NET address for the TC-24A in the System Controller field on the Group Setting screen. Register the 

M-NET address of the AG-150A on the TC-24A's Group Setting screen.

When combining TC-24A with the AG-150A controllers, the Setback, Hold, and External Input Function settings should be made 

only on the TC-24A. If using the Hold function on the TC-24A, schedule settings should not be made on the AG-150A controllers. 

To prohibit the operation of local remote controllers, set the prohibition settings either from the TC-24A or AG-150A, but not both.
