3.1 GENERAL
Pressing the ‘STATUS’ key displays the current chiller
or individual refrigerant system operational status. The
display will show the ‘highest priority’ information as
determined by the microprocessor.
For individual refrigerant system status or fault mes-
sages, the display shows information for up to two re-
frigerant systems.
The main categories of messages are:
• General Status Messages
• Unit Warnings
• Anticipation Control Status Messages
• Chiller Fault Status Messages
• System Fault Status Messages
These messages are described in detail below, with ex-
amples of each display. In each example ‘#’ is used as
applicable to represent the system number where mes-
sages apply to individual systems.
Each display is followed by a brief description of the
message.
