Status Codes History
The S9200U1000 stores the ten (10) most recent error
codes. These codes can be recalled for viewing during
troubleshooting and cleared if necessary
Recalling the Status Code History
You may perform the following procedure multiple times to
confirm that you have viewed all the currently stored error
codes.
To recall the error code history and display it via the red
status LED, perform the following:
1.
Jumper the thermostat screw-terminal R/2 to screw-
terminal D/1.
• Within 0.5 seconds, the red status LED stops
normal operation and turns on solid to indicate
that the jumper is sensed.
2.
Keep the thermostat screw-terminals R/2 to D/1
jumpered.
• After a 5 second time-out, the red status LED
turns off, indicating that error code recall is
pending.
3.
Within 10 seconds of the red status LED turning off,
remove the jumper from thermostat screw-terminals
R/2 to D/1.
• This activates the error code recall.
IMPORTANT
If the R/2 to D/1 terminal jumper is not removed
within the 10 seconds, the history is erased.
4.
Each saved error code blinks once on the red status
LED, starting with the most recently stored error
code.
NOTE: If there are no error codes to display, the red
status LED immediately returns to normal
operation.
5.
After last error code displays, the red status LED
returns to normal operation.
Clearing the Status Code History
This procedure erases the entire history of fault (error)
codes.
IMPORTANT
Once this procedure is performed, it cannot be
undone.
To clear the current error code history, perform the
following:
1.
Jumper the thermostat screw-terminal R/2 to
terminal
D/1.
• Within 0.5 seconds the red status LED stops
normal operation and turns on solid to indicate
that the jumper is sensed.
2.
Keep the thermostat screw-terminal R/2 to D/1 jum-
pered.
• After a 5 second time-out, the red status LED
turns off.
• After a 10 second time-out, the red status LED
turns on solid to indicate that the error history is
being cleared.
3.
When the error history is cleared, the red status
LED returns to normal operation.
4.
Remove the thermostat screw-terminal R/2 to termi-
nal D/1 jumper.
EnviraCOM
™
Communication
EnviraCOM™ communication is a standard feature on the
S9200U1000. EnviraCOM™ can be used to control
system operation by way of an EnviraCOM™ enabled
thermostat and perform advanced diagnostics when
connected to EnviraCOM™ enabled diagnostic tools such
as the web based EnviraLNK® remote diagnostics
application, the OnWatch QuickLook™ 72 and the
W8735D Telephone Access Module (TAM). In addition to
alarms, key information such as state and flame current
can be sent over the EnviraCOM™ bus. See Table 14.
