Access Level Required: VIEW
The OptiView Panel restricts certain operations based on
access level and password entry by the operator. Three
different access levels are View, Operator, and Service.
The access levels are listed in hierarchial order beginning
with the lowest level and proceeding to the highest level.
Users logged in under higher access level may perform
any actions permitted by lower access levels.
VIEW: The panel defaults to the lowest access level
which is termed VIEW. In this mode, the chiller op-
erating values and setpoints can be observed, but no
changes can be made.
OPERATOR: The second access level is termed OP-
ERATOR and will allow the customer to change all of
the setpoints required to operate the chiller system. The
OPERATOR access level reverts to the VIEW level
after 10 continuous minutes without a keypress.
SERVICE: In the event that advanced diagnostics are
necessary, a SERVICE access level has been provided.
Only qualified service personnel utilize this access level.
This level provides advanced control over many of the
chiller functions and allows calibration of many of the
chiller controls.
