4.5 Main Menu (AG)—Operating Status
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 (see 5.3.1 - Short Cycle Control).
4.6 Main Menu (AG)—View/Set Control Setpoints
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.
