END OF CYCLE

AFTER DELAY-TO-FAN--ON PERIOD ENDS, CIRCULATING AIR FAN IS ENERGIZED AT HEATING SPEED. THE (OPTIONAL) ELECTRONIC AIR CLEANER AND HUMIDIFIER ARE ENERGIZED.

WHEN THERMOSTAT IS SATISFIED, CONTACTS OPEN AND THE GAS VALVE IS DE-ENERGIZED. AFTER PROOF OF FLAME LOSS, INDUCER STARTS 5 SECOND POST SURGE AND (OPTIONAL) HUMIDIFIER IS DE-ENERGIZED. THE DELAY-TO-FAN-OFF PERIOD BEGINS (180 SECONDS)

AFTER THE DELAY-TO- FAN-OFF PERIOD ENDS, THE CIRCULATING AIR FAN AND (OPTIONAL) ELECTRONIC AIR CLEANER ARE DE-ENERGIZED.

THE RETRY SEQUENCE PROVIDES A 60 SECOND WAIT BEFORE IGNITION RETRY. RETRY IS ATTEMPTED WITH AN ADDITIONAL 10 SECONDS OF IGNITOR WARM-UP TIME.

IF IGNITION ATTEMPT IS

UNSUCCESSFUL, ONE

MORE RETRY WILL BE

MADE BEFORE THE

CONTROL BOARD GOES

INTO SYSTEM LOCKOUT.

IF FLAME IS DETECTED, THEN LOST, THE CONTROL BOARD WILL REPEAT THE INITIAL IGNITION SEQUENCE FOR A TOTAL OF SIX RECYCLES. AFTER SIX UNSUCCESSFUL RECYCLE ATTEMPTS, THE CONTROL WILL GO INTO SYSTEM LOCKOUT.

IF SYSTEM IS IN LOCKOUT, THE MODULE WILL RESET ITSELF AFTER 60 MINUTES OR MAY BE MANUALLY RESET BY INTERRUPTING THE POWER TO THE FURNACE AT THE DISCONNECT OR INTERRUPTING THE CALL FOR HEAT AT THE THERMOSTAT. IF THIS DOES NOT RESTART THE SYSTEM,
