• Before performing a test run, verify that the group setting has been performed and the startup sequence for the interlocked
operation setting has been completed.
• It may take approximately 10 minutes from power on until the local remote controller becomes operable. By pressing the operation/
Stop button on the touch panel on AG-150A the remote controller will become operable right away.
Test run procedure
1 Turn the AG-150A and all air conditioning units on.
2 Select the group to be tested on the Monitor/Operation screen and run the test.
3 Check for proper operation of each air conditioning unit during test run (e.g., check to see if cold (or warm) air comes out of the
supply air outlet on each indoor unit)
4 After confirming that all units are operating properly, stop the units either from AG-150A or from the remote controllers.
* Please refer to the Install Manual that came with the indoor unit for further details on the test run method.
1. To control a K control model
* Set AG-150A address to “000” when a K transmission converter is
connected. Always set to the main system controller when the
address is “000”.
* Set the address of the K-control indoor units to a larger number
than those of the M-transmission models of indoor units.
* When using a group setting for the K control model, set only the
indoor unit that belongs to that group.
* Set the minimum indoor unit address in the group for the K control
model group number.
1. External signal input function
* External signal input requires the external I/O adapter (PAC-YG10HA) sold separately.
