Display
The display presents information to the operator. This
information includes setpoint and temperature, unit operating
information, gauge readings, temperatures and other
information as selected by the operator.
The Standard Display of box temperature and setpoint is
shown here. The CYCLE-SENTRY Icon in the upper right of
the display shows the unit is running in CYCLE-SENTRY
(Start-Stop) Mode. The unit has a setpoint of 2 C, and an actual
box temperature of 2.1 C. The down-pointing arrow at the left
side of the display shows the unit is cooling.
The four keys under the display are termed "soft" keys. The
functions of these keys change depending on the operation
being performed. The function of each soft key is shown by
labels in the display located directly above each soft key. In
the example shown above, pressing the left soft key accesses
the SETPOINT and pressing the right soft key accesses the
MAIN MENU. The other two soft keys access the GAUGES
menu and SENSORS menu as shown by the labels above the
keys.
