be turned off. The unit and all zones are turned On and Off
simultaneously using the On and Off hard keys at the left side of the
display.
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 present. The TemperatureWatch Display (
Figure 31, p. 47 )
will remain on until any key is pressed or a Check, Prevent, or Shutdown
alarm occurs.
The TemperatureWatch Display shows the return air temperature and
setpoint for each zone. Tenths of a degree are not shown by the
TemperatureWatch display. The large numbers allow unit conditions to be
checked from a distance. Pressing any soft key returns the display to the
Standard Display.
Figure 31. Two Zone TemperatureWatch Display
If an alarm condition (other than a Log Alarm) is present, the
TemperatureWatch Display will not appear. If an alarm condition occurs
while the TemperatureWatch Display is present, the display will return to the
Standard Display.
If the Defrost Key or Cycle Sentry Key is pressed, the display will return to
the TemperatureWatch Display immediately after the defrost cycle is
initiated or the operating mode is changed.
In the Three Zone TemperatureWatch display, the Menu soft key label covers
the Zone 3 label as shown (
Figure 32, p. 48 ).
