7.25
Load_Shed_
Option
0 0 15 Option
Load shedding option used to disable half of available mechanical
cooling.
Select the load shedding input signal source:
0− No load shedding.
1− Special case. Shed all compressors when DI−3 opens. M2 v7.07
and later.
2− EM1 GLO (A55_P265−3) (economizer DIP NOT set to global
mode).
4− DI1 (A133_P194−1, DIP set to GP)
6− DI2 (A133_P194−2, DIP set to GP)
8− DI1 (A133_P194−1, DIP set to MGV).
10− DI2 (A133_P194−2, DIP set to MGV)
12− DI1 (A133_P194−1, DIP set to VAV)
14− DI2 (A133_P194−2, DIP set to VAV)
These options select load shedding that will round up (fractional com-
pressors on).
1 compressor unit – compressor is not disabled.
3 compressor unit – only compressor 3 is disabled.
Add one to any option to select load shedding that will round
down (fractional compressors off).
1 compressor unit – compressor is disabled.
3 compressor unit – compressors 2 and 3 are disabled.
7.26 BACnet_MAC 0 128 128
Address /
Option
BACnet MAC Address. A value of 0−127 sets the BACnet MAC ad-
