Controller Communications Limitations
Each type of Controller device is designed to communicate with a
limited quantity of indoor units. The quantity of indoor units that can
be connected to a single control communications cable, therefore,
will be defined by the control device on that cable with the smallest
Maximum Indoor Unit Quantity as shown in the tables at right.
Group Number
If the building operator wants to know which indoor units are on each outdoor unit, and multiple systems serve a building:
• Assign a Group Number to each system. If there are more than 16 indoor units on a system, multiple Group Numbers may be necessary.
If the building owner wants to know which indoor units are on each floor:
• Assign a different group number for each floor. If there are more than 16 indoor units on a floor, multiple Group Numbers may be
necessary.
Member Number
Can be assigned at will or for example, can follow the room layout on each floor.
For each LG Central Controller product provided on the project, devise a central control address schedule and assign a central control
address to each indoor unit(s) Hydro Kit(s), and ERV(s) units. Record this central control address for each component in the column provided
on the Pre-commissioning Device Configuration Worksheet.
Upload Central Control Address to the Indoor Units
For all ducted, vertical and floor standing indoor units, the central control address must be assigned using a wired zone controller. Wall-
mount, ceiling cassette, ceiling suspended, and the wall / ceiling convertible indoor units, the central control address can be assigned using a
wireless handheld controller or a wired zone controller.
