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.

Field Startup

The Field Startup Group password is + + - - + +
<Enter>. The Field Startup Group contains items that
are primarily associated with Field Commissioning of
the chiller as well as the fundamental control and
protection of the chiller subsystems. If the field
startup password is entered, the display goes to the
menu defined below. If a key is not pressed every 10
minutes in this password protected menu, the display
returns to the Chiller Operating Mode display of the
Chiller Report, and the password must be entered
again to return to this menu.
