Control Center
The YORK OptiView™ control center LCD Graphic
Display and keypad is the interface for starting, stop-
ping, configuring, monitoring, and commanding the
chiller controls. The control center is a microproces-
sor based system for centrifugal chillers. It controls
the LCHLT and maintains safe operation. It is factory-
mounted, wired and tested.
The graphic display allows the presentation of operat-
ing parameters in logical groups on screens and can
trend data to present a graphical representation of pres-
ent or historical operation of the chiller. The locations
of various chiller parameters are clearly and intuitively
marked. Instructions for specific operations are provid-
ed on many of the screens. The screens and navigation
are shown in the Optiview™ Control Center Functions
and Navigation section of this manual.
Eight buttons are available on the right side of the
panel, and are primarily used for navigation between
the system screens. At the base of the display are 5 ad-
ditional buttons. The button functions are redefined
based on the currently displayed screen. The area to
the right of the keypad is used for data entry with a
standard numeric keypad provided for entry of system
setpoints and limits.
The Decimal key provides accurate entry of
setpoint values.
A +/- key has also been provided to allow entry
of negative values and AM/PM selection dur-
ing time entry.
In order to accept changes made to the chiller
setpoints, the Check key is provided as a uni-
versal ‘Enter’ key or ‘Accept’’ symbol.
In order to reject entry of a setpoint or dismiss
an entry form, the ‘X’ key is provided as a uni-
versal ‘Cancel’ symbol.
Cursor Arrow keys are provid-
ed to allow movement on
screens which contain a large
amount of entry data. In addi-
tion, these keys can be used to
scroll through history and
event logs.
The graphic display also allows numerical information
to be represented in both English (temperatures in °F
and pressures in PSIG) and Metric (temperatures in °C
and pressures in kPa) mode. It also has the ability to
display many languages.
