System Status And Error Codes; Reading The Led Flash Sequence - Smith BTF-80 SERIES 210 Installation And Operating Manual

SYSTEM STATUS AND ERROR CODES

The micro-controller inside the gas control monitors the fl ammable vapour 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 "Troubleshooting Guidelines" to diagnose the problem
before attempting corrective action. See also "Flammable Vapour Sensor".

READING THE LED FLASH SEQUENCE.

The LED indicator light is active when the gas valve/thermostat is in operation. The light will normally show a fl ash
sequence of a short fl ash once every four seconds or a "Heartbeat" of alternating bright/dim. Multiple fl ash codes indicate
an error and can be read as follows:
Example: Corrective Action Number 9, Six-Two Flash, three second pause. For this code, the LED indicator light will
make six bright fl ashes, pause for one second and then make two more bright fl ashes. The LED will pause for three
seconds and repeat the six-two cycle of fl ashes.
