Operating Instructions
48
The unit is running in Cycle Sentry Mode as
shown by the Cycle Sentry Icon in the upper right
corner of the display. If the Cycle Sentry icon is
not present, the unit would be running in
Continuous Mode.
The USB Icon in the upper left corner of the
display will appear when a USB Flash Drive is
connected to the Flash Drive Only USB Port or a
PC computer is connected to the PC Only USB
Port on the Unit Control Panel.
Pressing the left soft key allows the user to change the
SETPOINT, and pressing the right soft key accesses the MAIN
MENU. The other two soft keys access the GAUGES menu
and the SENSORS menu.
NOTE: The functions of the GAUGES and SENSORS soft
keys may be re-assigned to better suit customer requirements.
The GAUGES and SENSORS functions are always available
from the Maintenance Menu.
The TemperatureWatch Display
The TemperatureWatch Display appears 2 ½ minutes after the
Standard Display appears so long as there is no key activity
and no check, prevent or shutdown alarms are present. The
TemperatureWatch Display will remain on until any key is
pressed or a check, prevent or shutdown alarm occurs.
The TemperatureWatch Display shows the box temperature
and setpoint. The large numbers allow unit conditions to be
checked from a distance. The box temperature is that measured
by the controlling sensor, usually the return air sensor. The box
temperature in Figure 37 is 35.8 F (2.1 C) with a 35 F (1.7 C)
setpoint. The Cycle Sentry icon in the upper right corner of the
display shows that the unit is operating in Cycle Sentry Mode.
If the Cycle Sentry icon is not present, the unit is running in
Continuous Mode. The down-pointing arrow indicates that the
unit is cooling. Pressing any soft key returns the display to the
Standard Display.
