6-1. Batch operation/Stop (error reset) switches

• Before performing a test run, check that the group setting and interlock settings from the AG-150A and other controllers have been properly made.

• The batch operation function on the PAC-YG50ECA cannot be used to change the operation mode of the connected indoor units (including the test run mode). Units will be operated in the mode they are set to operate in. The PAC-YG50ECA does not have the function to automatically stop the test run in two hours as the remote controllers do.

1 Turn on all units and the PAC-YG50ECA. 2 Set the switches as follows. SW601: All set to OFF; SW606: “0”; SW607: “0” 3 Check that LD5 on PAC-YG50ECA is unlit (SW601: All set to OFF; SW606: “0”; SW607 “0”).

LD5 will be lit if the group setting and interlock setting from the AG-150A and other controllers have not been completed. LD5 will blink while M-NET is starting up (takes approx. 10 minutes to complete).

Turn SW603-1 from the OFF position to the ON position. The operation signal will be sent to the groups that are registered.

4 5 LD3 (SW601: All set to OFF; SW606: “0”; SW607 “0”) will be lit when the units are in operation. 6 Check each unit for proper operation (e.g., supply air comes out of the indoor unit outlet.). 7 Turn SW603-2 from the OFF position to the ON position to bring the units to stop. 8 Turn SW603-1 and SW603-2 to OFF at the completion of the test run.

When making the group setting for K-control units, make the setting only for the indoor units that belong to a given group. The group number given to a group of K-control units should be the same as the lowest address of the indoor units that belong to

the group.

If the K-control Y series units and other types of units (K-control Mr. Slim) are used in combination, a relay board is required.

The K- control Y series units cannot be connected to the same transmission lines as the other types of units.

Depending on the number of K-control units and transmission line length, a relay board may be required. Refer to the System

Design/Manual (control version) for details.

LOSSNAY units cannot be connected if they are connected to the K-control kit. Remote controller addresses do not need to be included in the group setting for a group of K-control units.
