17. Electronic Configure To Order (ECTO) Control Parameters
Description
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.
BACnet MAC Address. A value of 0−127 sets the BACnet MAC ad-
dress to that value; 128 sets the MAC address to the unit address set
on the ADDRESS DIP switch.
Discharge Air Control Cooling total reset limit. This limits the total DACC
reset allowed. Also used to reset free cooling setpoint (6.23).
Discharge Air Control Cooling return air reset setpoint. Also used to
reset free cooling setpoint (6.23).
Discharge Air Control Cooling return air reset proportional band. Also
used to reset free cooling setpoint (6.23).
Discharge Air Control Cooling return air reset adjustment band. 0
disables return air cooling reset. Also used to reset free cooling setpoint
(6.23).
Discharge Air Control Cooling outdoor air temperature cooling reset
setpoint. Also used to reset free cooling setpoint (6.23).
Discharge Air Control Cooling outdoor ambient temperature cooling
proportional band. Also used to reset free cooling setpoint (6.23).
Discharge Air Control Cooling outdoor temperature ambient cooling
adjustment reset band. 0 disables outdoor air cooling reset. Also used
to reset free cooling setpoint (6.23).
Discharge Air Control Heating reset limit. This limits the total DACH
reset allowed.
Discharge Air Control Heating return air heating reset setpoint.
Discharge Air Control Heating return air heating reset proportional
band.
Discharge Air Control Heating return reset adjustment band.
0 value disables return air heating reset.
Discharge Air Control Heating outdoor temperature reset setpoint.
Discharge Air Control Heating temperature reset proportional band.
Discharge Air Control Heating outdoor temperature reset adjust-
ment band.
0 disables outdoor temperature heating reset
