Understanding when the HOME screen appears
NOTE:
This section only applies to i.Series models.
The monitoring system displays the HOME screen if the HOME button is pressed from any other screen.
If another screen is displayed, and there is no interaction for two minutes, the monitoring system returns to
the HOME screen. The only exceptions are the screens used to enter a password.
6.2.5
Understanding the temperature graph and when it appears
NOTE:
This section only applies to i.Series models. For instructions to enable or disable
the temperature graph, see Section 4.5, “Enabling and disabling the temperature
graph.”
HOME screen with temperature graph (circled)
While there is power to the monitoring system, temperature data from the upper temperature probe is
collected real-time, and the past 24 hours of collected data is stored. The temperature graph displays the
temperature data for the past 24 hours of operation.
When this feature is enabled, this graph appears on the bottom of the MAIN screen whenever the buttons
have not been pressed for one minute, and there are no active alarms. The graph clears if a button is pressed
or an alarm activates.
The vertical axis represents the temperature, while the horizontal axis represents time.
The screen displays the previous 24 hours of readings from the upper temperature probe. The current
temperature always appears on the right side of the screen. Each four hour period is separated by a vertical
line. As time progresses, the display changes so the most current reading is always on the right.
The horizontal line at the top of the graph indicates the High Alarm setpoint, while the line at the bottom
indicates the Low Alarm setpoint. If the temperature goes outside the limits, that section of the graph flashes.
If the AC power fails, the monitor continues to collect and display temperature data on the graph so long as
there is backup power. If the AC power is restored before the backup power fails, there is no interruption
in data collection: the temperature that is displayed on the graph for eight hours earlier was the temperature
eight hours ago.
If the backup power fails, the monitor stops displaying temperature data and stops collecting new
temperature data. However, the past 24 hours of data are retained. When the power is restored, the stored
data is displayed, and the monitor resumes collecting and displaying real-time temperature data. In this
case, there is an interruption in data collection: the temperature that is displayed on the graph for eight
hours earlier was actually the temperature at eight hours before the backup power failed.
