★Example: If one IDU is 5 HP and the address code is set to 1, then the query address at the centralized
controller side or wired controller side is 1. If one IDU is 20 HP and the address code is set to 5, then this
IDU has four address codes, which are 5, 6, 7, and 8, but the query address at the centralized controller
side or wired controller side is 5.
