NOTE: OptiView
™
Control Center Screens shown may NOT represent the exact screens according to the software version utilized.
OVERVIEW
This screen displays a cutaway view of the chiller
evaporator. All setpoints relating to the evaporator side
of the chiller are maintained on this screen. Animation
of the evaporation process indicates whether the chiller
is presently in a RUN condition. Animation of the liq-
uid flow lines indicate chilled liquid flow.
DISPLAY ONLY
Chilled Liquid Flow Switch (Open/Closed)
Displays whether the liquid flow is present in the evap-
orator.
Chilled Liquid Pump Start Contact (Open/
Closed)
Displays the status of the contact on the I/O board used
to control the Chilled Liquid Pump Motor Starter.
Evaporator Pressure
Displays the present refrigerant pressure in the evaporator.
Evaporator Saturation Temperature
Displays the present saturation temperature in the
evaporator.
Return Chilled Liquid Temperature
Displays the temperature of the liquid as it enters the
evaporator.
Leaving Chilled Liquid Temperature
Displays the temperature of the liquid as it leaves the
evaporator.
Chilled Liquid Flow
Displays the rate of chilled liquid flowing through the
evaporator. This text and data field only appears if
