Fault Code Retrieval

To retrieve fault codes, push and release ERROR button on control board. The LED will flash the
last five error codes, beginning with the most recent. If there are no fault codes in memory, the LED
will give two green flashes. To clear the fault code memory, push and hold the ERROR button for
at least five seconds. The LED will give three green flashes when the memory has been cleared.

Notice - Only a qualified service technician should use this feature.

Fault code retrieval functions will work only if there are no active thermostat signals.

NOTES:
1. Si l'un des fils d'origine fourni avec ce four doit filage doit être remplacé,
il doit être remplacé avec le fil ayant un degré de température d'au
moins 221 degrés F (105 degrés C ).
2. Seulement des marettes pour fil de cuivre.

NOTES:
1. If any of the original wire as supplied with the furnace must be replaced,
it must be replaced with wiring material having a temperature rating of at
least 221 degrees F (105 degrees C).
2. Connectors suitable for copper conductors only.
