THE HOME SCREEN
This screen will appear each time the Interface Panel has
been powered up (default). It can also be accessed from
the main menu by selecting Home.
Many of the operating characteristics for each zone can
be viewed from here. The upper left hand corner of the
screen tells you which zone is currently being viewed, and
the zone setpoint box allows you to enter the number of
any other enabled zone that you may wish to view.
The square grey box in the lower left hand corner will
contain a red blinking dot if any zone being viewed has an
active alarm condition, or a yellow blinking dot if any zone
has an active warning..
This screen will display basic alarm information for the se-
lected zone, as well as the current temperature and zone
setpoint. At the bottom of this screen, basic status infor-
mation is provided about valves and the fan. The Defrost
box provides information when a defrost is underway.
The four Cooling Mode screens allow each zone to
operate with four separate groups of setpoints. This
screen shows the setpoints available for congura-
tion based upon the selecting mode on the Current
Zone Conguration page. Most importantly, the Liq-
uid On and Off temperatures should be set, as well as
the Fan On and Off temperatures. It is also recom-
mended to set the Alarm High and Low temperatures
for each Mode.
