ENTRY KEYS

Enter/Adv Key
The ENTER/ADV 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/ADV key is not pressed after a value is changed,
the changes will not be "entered" and the original val-
ues will be used to control the chiller.
Programming and a description on the use of the ↑ (UP)
arrow key, and ↓ (DOWN) arrow, and ENTER/ADV
keys are covered in detail under the SETPOINTS, and
UNIT keys.
