Emerson DE Manuel D’Utilisation

The Operating Status is intended to provide the user with displayed information concerning what the 

control is calling for the system to do. 

For example: The display indicates the chilled water valve is 68% open. On a new call for cooling, it 

takes several seconds for the valve to travel from full closed to 68% open. So when the display reads 

68%, it may take a few seconds for the valve to actually open 68%. Also, if the display indicates a com-

pressor is operating but the compressor has not turned on yet, it may be off because of the short cycle 

Control setpoints can be reviewed and/or changed through the display. The following table lists the 

default setpoints and their allowable ranges.

*Unit will operate at these conditions but will not control to these extremes of conditions.

Selecting SETUP SYSTEM will step to the following menu:

• SETUP OPERATION
• SELECT OPTIONS
• CALIBRATE SENSORS
• CALIBRATE VALVE ACTUATOR
• SELECT CONTROL ALGORITHM
• SELECT HUMIDITY SENSING MODE
• SET STATUS DISPLAY
• CHANGE PASSWORDS

NOTE
There may be some time lapse before a specific component matches the displayed number.
