Advanced Microprocessor with Graphics Control Setup

4.5Main 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.

NOTE

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

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).

4.6Main 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.
