The UCM will determine which screen will be displayed after looking at the
current Operating Mode. If the Operating Mode is “Ice Making” or “Ice
Making Complete”, ACTIVE ICE TERMINATION SETPOINT will be displayed.
Otherwise, ACTIVE CHILLED WATER SETPOINT will be shown.
The flowcharts also list the setpoint ranges, default options and a brief
description of the item, when necessary. This information is shown in the
lefthand column of the page, adjacent to the appropriate display.
Auto/Stop Keys
The chiller will go through a “STOPPING” mode when the Stop key is
pressed if a compressor is running. This key has a red background color
surrounding it, to distinguish it from the others.
If the chiller is in the Stop mode, pressing the Auto key will cause the UCM to
go into the Auto/Local or Auto/Remote mode, depending on the Setpoint
Source setting. The Auto key has a green background color.
When either the Auto or Stop key is pressed, Chiller Operating Mode
(Chiller Report Menu) will be shown on the display.
Power Up
When power is first applied to the control panel, the Clear Language Display
goes through a self-test. For approximately five seconds, the readout on the
display will be:
SELF TEST IN PROGRESS
During the self-test, the backlight will not be energized. When the tests are
successfully complete, the readout on the display will be
6200 xxxx-xx [TYPE] configuration
Updating Unit Data, Please Wait
When updating is successfully completed, the system will default to the first
display after the Chiller Report header:

and the backlight will be activated.
