The Entry Keys allows the user to view, change pro- grammed values. The ENTRY keys consist of an UP ARROW key, DOWN ARROW key, and an ENTER/ADV key.
UP AND DOWN ARROW KEYS
Used in conjunction with the OPER DATA and HISTORY keys, the UP and DOWN arrow keys allow the user to scroll through the various data screens. Refer to the section on “Display/Print” keys for specific information on the displayed information and specific use of the UP and DOWN arrow keys.
The UP and DOWN arrow keys are also used for pro- gramming the control panel such as changing cooling
setpoints, setting the daily schedule, changing safety setpoints, chiller options, and setting the clock.
ENTER/ADV key
The ENTER key must be pushed after any change is made to the cooling setpoints, daily schedule, safety setpoints, chiller options, and the clock. Pressing this key “enters” the new values into memory. If the EN- TER key is not pressed after a value is changed, the changes will not be “entered” and the original values will be used to control the chiller.
Programming and a description on the use of the UP and DOWN arrow and ENTER/ADV keys are covered in detail under the SETPOINTS, and UNIT keys.
