When the task of site adjustment is subdivided into smaller tasks as shown in the figure below, the tasks can be broadly grouped into 3 steps. The benefit of following these 3 steps when carrying out the tasks of site adjustment is that if troubles do arise, it will be clear which step caused the problem. This makes it easier to solve problems and these results in a more efficient execution of site adjustment tasks.

Carry out site adjustment, by following the step-by-step instructions shown below.

Step 1 G-50A test run

Check that the air conditioners and controllers are correctly configured and that the air conditioner works.

Step 2 PC connections and settings

Connect and set up the software and hardware on the PC with BACnet IF installed.

Check that it is ready for operation.

▪For the test operation method of the air conditioner and centralized controller G-50A, refer to the relevant installation manuals.

▪Check that only the air conditioner test operation has been completed before starting Step 1.

▪See Chapter 5 in this booklet for details.

Step 3 BACnet IF system test run

Check that the Building Automation System can correctly operate air conditioner units of all the managed systems by issuing BACnet IF commands.
