BLOWER OFF DELAY SELECT

LED CODE	STATUS

CONTINUOUS OFF - Check for 115VAC at L1 and L2, and 24VAC at SEC-1 and SEC-2. CONTINUOUS ON - Control has 24V power.

RAPID FLASHING - Line voltage (115V) polarity reversed. If twinned, 24V power to one furnace may be out of phase with 24V power to other furnace.

EACH OF THE FOLLOWING STATUS CODES IS A TWO DIGIT NUMBER WITH THE FIRST DIGIT DETERMINED BY THE NUMBER OF SHORT FLASHES AND THE SECOND DIGIT BY THE NUMBER OF LONG FLASHES.

11NO PREVIOUS CODE - Stored status codes are erased when power (115V or 24V) to control is interrupted or 48 hours after each fault is cleared.

12BLOWER ON AFTER POWER UP (115V OR 24V) - Blower runs for 90 seconds, if unit is powered up during a call for heat (R-W closed).

13LIMIT OR FLAME ROLLOUT SWITCH LOCKOUT - Auto reset after three hours. Flame rollout switch requires manual reset. Refer to #33.

14IGNITION LOCKOUT - Control will auto-reset after three hours. Refer to #34.

21GAS HEATING LOCKOUT - Control will NOT auto reset.

Check for: - Stuck gas valve relay on control or miswire to gas valve circuit.

22ABNORMAL FLAME-PROVING SIGNAL - Flame is proved while gas valve is de-energized. Inducer will run until fault is cleared.

Check for: - Stuck-open gas valve or leaky gas valve.

23PRESSURE SWITCH DID NOT OPEN Check for:

- Obstructed pressure tubing. - Defective pressure switch (stuck closed).

24 SECONDARY VOLTAGE FUSE IS OPEN

Check for: - Short circuit in secondary voltage (24V) wiring.

31PRESSURE, DRAFT SAFEGUARD, OR AUXILIARY LIMIT (when used) SWITCH DID NOT CLOSE OR REOPENED - If open longer than five minutes, inducer shuts off for

15 minutes before retry. Check for:

- Proper vent sizing and condensate pitch. - Inadequate combustion air supply.

- Vent restriction or high winds. - Low inducer voltage.

-Defective inducer motor or start capacitor.

-Defective pressure switch or connections. If it opens after trial for ignition period, blower will come on for 90 second recycle delay.

-Disconnected or obstructed pressure tubing.

33LIMIT OR FLAME ROLLOUT SWITCH IS OPEN - If open longer than three minutes, code changes to #13. Check for:

- Defective blower motor or start capacitor. - Dirty filter or restricted duct system.

- Loose blower wheel. - Defective switch or connections.

-Inadequate combustion air supply (flame rollout switch only).

-Open flame rollout switch, manual reset.

34IGNITION PROVING FAILURE - Control will try three more times before a lockout #14 occurs. If flame signal lost after trial for ignition period, blower will come on for 90 second recycle delay.

Check for: - Oxide buildup on flame sensor (clean with fine sandpaper).

- Proper flame sense microamps (.5 microamps D.C. minimum).

- Gas valve turned off. - Manual shut-off valve.

-Green wire MUST be connected to furnace sheet metal.

-Inadequate flame carryover or rough ignition.

-Low inlet gas pressure.

COMPONENT TEST

To initiate the component test sequence, shut OFF the room thermostat or disconnect the "R" thermostat lead. Briefly short the TEST terminal to the "C" terminal. Status LED will flash code and then turn on the inducer motor, hot surface igniter, blower motor-heat speed, and blower motor-cool speed for 10-15 seconds each.
