information and specific use of the ↑ (UP) and ↓

safety set points, chiller options, and setting the clock.
ENTRY KEYS
Enter/Adv Key
The ENTER/ADV key must be pushed after any change
is made to the cooling set points, daily schedule, safety
set points, 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 SET POINTS, and
UNIT keys.
