Basic Controls
This section describes the basic functions of the chiller
control system. We explore this from two vantages:
• Menus
• Data Displays
Menus
This system has three functional menus:
1. Main Menu – persistent across all displays.
2. Devices Menu – persistent across devices functions.
3. Settings Menu – persistent across settings functions.
Main Menu
The Main Menu is part of the banner of all displays:

For debugging purposes, the system provides a
display of raw inputs and outputs.
Displays compressor 1 detail. All the
compressors' pages can be accessed.
Displays Alarm Page.
Displays key process indicators – all fluid
temperatures, suction and discharge pressures
in large format and other parameters. Also, it
displays ambient temperature, condenser fan
speed for air-cooled chillers.
Displays fluid temperatures against system
demand in a 1-hour trend for water-cooled
chillers. Displays evaporator Fluid temperatures,
ambient temperature, and condenser fan speed
for air-cooled chillers.
