SYSTEM STATUS AND ERROR CODES

The micro-controller inside the gas control monitors the
fl ammable vapor safety features, the ignition sequence,
temperature settings and overall operation of the heater.
If any of these parameters does not operate properly the
controller will shut down the water heater, diagnose the
failure and fl ash an error code. The table below lists the
System Status Codes for the Honeywell control. Refer to
it and to the "Trouble Shooting Guidelines" to diagnose
the problem before attempting corrective action. See also
"Flammable Vapor Sensor".
