The terms “Group,” “Block,” and “EC” used in this manual are defined as follows: Group: Group is a group of air conditioning units and controllers and is the smallest unit that the AG-150A can control. The maximum number of units and controllers that each group can contain is 16.
3. Product features The controller described in this manual is a centralized controller that can be operated over the Web. Any connected air conditioning systems can be operated or monitored directly from the controller or over the Web using browser software. Refer to the Web browser operation manual (separate volume) for how to use this functions.
This function is used to make the basic settings for the floor layout and display position Floor Layout of the groups. Up to 384 errors can be stored in memory. (128 errors per AG-150A or expansion Error history monitor controller (64 unit errors, 64 communication errors))
*1: The item and range that can be operated or monitored depend on the function of the indoor unit. *2: The maximum number of the controllable units varies, depending on the indoor unit. *3: “Air To Water” on the AG-150A screen indicates Booster unit group and Water HEX unit group. * Main and Sub system controllers The controller described in this manual can only be used as a Main controller, not as a Sub controller.
