3.8 FUNCTION KEY
Pressing the Function key only displays the same mes-
sage as pressing the Status key. Pressing the Function
key followed by another display key will scroll through
all the data available under that key once. E.g., pressing
the Function key followed by the System 1 Data key will
result in scrolling through the 5 displays shown in Sec-
tion 3.3 without the need to press the System 1 Data key
to scroll to the next display. After scrolling through the
data, the display returns to the status message.
The following keys can be scrolled using the Function
Key: Chilled Liquid Temps, System # Data, Motor Cur-
rent and Options.
