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
jumpered.
• 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
terminal 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.
