Honeywell Sola Controller Diagnostics - Ace Heating Solutions Atlas A050 Operating And Maintenance Manual

Each status variable displayed in the trend analysis is represented by a different colored line, as follows:
x
First status variable: Green
x
Second status variable: Yellow
x
Third status variable: Red
x
Fourth status variable: Blue
No more than two different measurement units (such as degrees), are allowed for the status variables selected in the
trend analysis graph. Attempts to add a status variable with a third measurement unit are rejected.
Status older than the sample time period is dropped from the right end of the curve as newer status appears on the left
end of the curve.
Trend data can be viewed in one-second (most recent 60 second time period), 15-second (most recent 15-minute time
period), and hour (most recent 24 hour time period) intervals.
Pressing the Stop button will pause trend data updates of the graph. The graph freezes the view when stopped. However,
trend data sampling from the Honeywell Sola Controller continues regardless whether the graph update is stopped or not.
Restarting the updates causes the graph to be refreshed with the latest data samples.
Pressing the Clear button will clear the trend sample data for a Honeywell Sola Controller. All trend data for the Honeywell
Sola Controller is cleared including status variables that are not included in the graph. The user is asked to confirm this
action before proceeding.
Trend Analysis Snapshot
The trend analysis snapshot file is stored in Comma Separated Value (CSV) format in the System Operator Interface so it
can be imported into a spreadsheet program such as Microsoft Excel.
The trend analysis snapshot file can be viewed in graph form on the System Operator Interface. It is also accessible in an
Ethernet FTP session with the System Operator Interface. This FTP session can be used to export the trend analysis
snapshot file.

4-36 Honeywell Sola Controller Diagnostics

The diagnostic page displays analog and digital I/O status of the Honeywell Sola Controller. The digital I/O data is
displayed as LEDs that are either on (green) or off (red). Not all digital I/O can be displayed at the same time on the page,
so a horizontal scroll bar is used to move the view left and right to show all digital I/O data.
Temperature sensors also display the current sensor state, i.e., whether there is a fault condition or the sensor is in a
normal monitoring state. The user can toggle between displaying the Honeywell Sola Controller digital and analog I/O.
The Digital or Analog button on the bottom of the diagnostic page changes the I/O displayed to the type indicated by the
button. The following data is displayed on the Honeywell Sola Controller diagnostics page.
