The most important information about the selected zone is
displayed here:
ZONE SELECTED – This setpoint box allows the user to
enter the ID number of the Evaporator zone that they wish
to view on this screen. When a different zone number is
entered and submitted, the screen data will be updated
with the information from that zone. This same setpoint
box appears on many of the screens.
DATE - The actual date will be displayed in this box.
The date must rst be set correctly on the Conguration
screen. The primary use of the date feature is to provide
a date stamp for Warnings and Shutdowns. Refer to the
section entitled Setting the Date and Time for further in-
formation.
TIME - The actual time will be displayed in this box.
The time must rst be set correctly on the Conguration

locations which observe Daylight Savings Time. The pri-
mary use of the time feature is to provide a time stamp
for Warnings and Shutdowns. Refer to the section entitled
Setting the Date and Time for further information.
