Operator Settings Group Heading
Important! FACTORY DEFAULT SETTINGS: Menu
items that are programmable using the keypad may
have a selectable choice that is listed as Factory
Default. This Factory Default setting is the software
default that is initially factory-programmed for a new
module assembly and may NOT be the correct
setting for a specific operating chiller. Always review
all settings when any module is replaced to verify
that the settings agree with the desired settings that
were selected at initial startup or programmed at the
factory.
The Operator Settings Group sequence follows.

keystrokes will be echoed to the screen as a visual

“Invalid Password”.
If the password status is unlocked, the password
message will be “Press (Enter) to Lock”. Pressing
