®
interface [BAC-HD150]
CITY MULTI can easily combine into a Building Management System (BMS) via the BACnet
®
and M-NET adapter BAC-HD150.
BACnet
®
is an opened transmission protocol widely used at BMS, and related equipment control.
CITY MULTI is therefore compatible with large-scaled BMS management via BACnet
®
.
BAC-HD150 can control up to 50 units/groups (including LOSSNAY). Up to 150 units/groups (including LOSSNAY) can be controlled
from one BAC-HD150 with three expansion controllers PAC-YG50ECA. (50 units/PAC-YG50ECA)
When the dual set point function is used, no expansion controllers can be connected, and only up to 50 units/groups can be
controlled from each BAC-HD150.
