6 X340989P17

Service FactsSequence Of OperationThermostat call for heat (2-stage thermostat)Call for 1st stage only: R and W1 thermostat contacts close signaling the control module to run its self-check routine. After the control mod-ule has verified that the 1st stage pressure switch contacts are open and the limit switch(es) contacts are closed, the draft blower will be energized.

As the induced draft blower comes up to speed, the pres-sure switch contacts will close and the ignitor warm up period will begin. The igniter will heat for approx. 17 seconds, then the gas valve is energized in 1st stage to permit gas flow to the burners. The flame sensor confirms that ignition has been achieved within the 4 second ignition trial period.

As the flame sensor confirms that ignition has been achieved, the delay to fan ON period begins timing and after approx. 45 seconds the indoor blower motor will be energized at low speed and will continue to run during the heating cycle.

Call for 2nd stage after 1st stage: R and W2 thermostat contacts close signaling a call for 2nd stage heat. After a 30 second delay, the induced draft blower will be energized on high speed and the 2nd stage pressure switch contacts will close allowing the gas valve to be energized in 2nd stage and the indoor blower motor in high speed.

2nd stage satisfied, 1st stage still called: R and W2 thermostat contacts open signaling that 2nd stage heating requirements are satisfied. The induced draft blower is reduced to low speed allowing the 2nd stage pressure switch contacts to open and the gas valve is reduced to 1st stage. After approx. 30 seconds the indoor blower motor is reduced to low speed.

1st stage satisfied: R and W1 thermostat contacts open signaling that 1st stage heating requirements are satisfied. The gas valve will close and the induced draft blower will be de-energized. The indoor blower motor will continue to run for the heating fan off period (Field selectable at 90, 120, 150 or 180 seconds), then will be de-energized by the control module.

Thermostat call for heat (1-stage Thermostat)R and W thermostats close signaling a call for heat. 1st stage sequence of operation remains the same as above. 2nd stage delay will be reflective dip switch S7-1 and S7-2.

Reference the back of service facts for delay options.

Thermostat satisfied (1-stage Thermostat): Contacts open signaling the control module to close the gas valve and de-energize the induced draft blower. The indoor blower motor will continue to operate at high heat speed for approx. 30 seconds after the flames are extinguished and then is switched to low heat speed for the remaining FAN-OFF period.

Should overheating occur, or the gas supply fail to shut off, shut off the gas valve to the unit before shutting off the electrical supply. Failure to follow this warning could result in property damage, personal injury, or death.

▲ WARNING!

Indoor Blower TimingHeating: The ECM Fan Control controls the variable speed indoor blower. The blower “on” time is fixed at 45 seconds after ignition. The FAN-OFF period is field selectable by dip switches S7-3 and S7-4 on the Integrated Furnace Con-trol at 90, 120, 150, or 180 seconds. The factory setting is 90 seconds (See unit wiring diagram).

Cooling: The fan delay-off period is set by dip switches on the ECM Fan Control board connected to the Integrated Furnace Control. The options for cooling delay off is field selectable by dip switches S4-1 and S4-2.

The following table and graph explain the delay-off set-tings:

COOLING OFF - DELAY OPTIONS

* - This setting is equivalent to BAY24X045 relay benefit

** - This selection provides ENHANCED MODE, which is a ramping up and ramping down of the blower speed to provide improved comfort, quietness, and potential energy savings. See Wiring Diagram notes on the unit or in the Ser-vice Facts for complete wiring setup for ENHANCED MODE. The graph which follows, shows the ramping process.

BODILY INJURY CAN RESULT FROM HIGH VOLTAGE ELECTRICAL COMPONENTS, FAST MOVING FANS, AND COMBUSTIBLE GAS.

Service FactsPeriodic Servicing Requirements

▲ WARNING!Disconnect power to the unit before removing the blower door. Failure to follow this warning could result in person-al injury from moving parts.

1. GENERAL INSPECTION – Examine the furnace installation annually for the following items:

a. All flue product carrying areas external to the fur-nace (i.e. chimney, vent connector) are clear and free of obstruction. A vent screen in the end of the vent (flue) pipe must be inspected for blockage annually.

b. The vent connector is in place, slopes upward and is physically sound without holes or excessive corro-sion.

c. The return air duct connection(s) is physically sound, is sealed to the furnace and terminates out-side the space containing the furnace.

d. The physical support of the furnace should be sound without sagging, cracks, gaps, etc., around the base so as to provide a seal between the support and the base.

e. There are no obvious signs of deterioration of the furnace.

2. FILTERS – Filters should be cleaned or replaced (with high velocity filters only), monthly and more frequently during high use times of the year such as midsummer or midwinter.

3. BLOWERS – The blower size and speed determine the air volume delivered by the furnace. The blower mo-tor bearings are factory lubricated and under normal operating conditions do not require servicing. If motor lubrication is required it should only be done by a qualified servicer. Annual cleaning of the blower wheel and housing is recommended for maximum air output, and this must be performed only by a qualified servicer or service agency.

4. IGNITER – This unit has a special hot surface direct ignition device that automatically lights the burners. Please note that it is very fragile and should be han-dled with care.

▲ CAUTION!Do not touch igniter. It is extremely hot.

5. BURNER – Gas burners do not normally require scheduled servicing, however, accumulation of foreign material may cause a yellowing flame or delayed igni-tion. Either condition indicates that a service call is required. For best operation, burners must be cleaned annually using brushes and vacuum cleaner.

Turn off gas and electric power supply. To clean burn-ers, remove burner box cover (6 to 8 screws) and top burner bracket. Lift burners from orifices.

NOTE: Be careful not to break igniter when removing burn-ers.

Clean burners with brush and/or vacuum cleaner. Re-assemble parts by reversal of the above procedure. The burner box must be resealed when replacing box cover.

NOTE: On LP (propane) units, some light yellow tipping of the outer mantle is normal. Inner mantle should be bright blue. Natural gas units should not have any yellow tipped flames. This condition indicates that a service call is required. For best operation, burners must be cleaned an-nually using brushes and vacuum cleaner.

NOTE: On LP (propane) units, due to variations in BTU content and altitude, servicing may be required at shorter inter-vals.

▲ WARNING!CARBON MONOXIDE POISONING HAZARD

Failure to follow the service and/or periodic maintenance instructions for the furnace and venting system, could result in carbon monoxide poisoning or death.

6. HEAT EXCHANGER/FLUE PIPE – These items must be inspected for signs of corrosion, and/or deteriora-tion at the beginning of each heating season by a quali-fied service technician and cleaned annually for best operation. To clean flue gas passages, follow recommen-dations below:

a. Turn off gas and electric power supply.

b. Inspect flue pipe exterior for cracks, leaks, holes or leaky joints. Some discoloration of PVC pipe is nor-mal.

c. Remove burner compartment door from furnace.

d. Inspect around insulation covering flue collector box. Inspect induced draft blower connections from recuperative cell and to the flue pipe connection.

e. Remove burners. (See 4.)

f. Use a mirror and flashlight to inspect interior of heat exchanger, be careful not to damage the igniter, flame sensor or other components.

g. If any corrosion is present, contact a service agency. Heat exchanger should be cleaned by a qualified service technician.

h. After inspection is complete replace burner box cover, burners, and furnace door.

i. Restore gas supply. Check for leaks using a soap solution. Restore electrical supply. Check unit for normal operation.

7. COOLING COIL CONDENSATE DRAIN – If a cooling coil is installed with the furnace, condensate drains should be checked and cleaned periodically to assure that condensate can drain freely from coil to drain. If condensate cannot drain freely water damage could oc-cur. (See Condensate Drain in Installer’s Guide)

▲ CAUTION!Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.

Verify proper operation after servicing.

▲ WARNING!NEVER USE AN OPEN FLAME TO TEST FOR GAS LEAKS. AN EXPLOSION COULD OCCUR, CAUSING INJURY OR DEATH.

▲ WARNING!

The following warning complies with State of California law, Proposition 65.

This product contains fiberglass wool insulation!

Fiberglass dust and ceramic fibers are believed by the State of California to cause cancer through inhalation. Glasswool fibers may also cause respiratory, skin, or eye irritation.

PRECAUTIONARY MEASURES

● Avoid breathing fiberglass dust.

● Use a NIOSH approved dust/mist respirator.

● Avoid contact with the skin or eyes. Wear long-sleeved, loose-fitting clothing, gloves, and eye protection.

● Wash clothes separately from other clothing: rinse washer thoroughly.

● Operations such as sawing, blowing, tear-out, and spraying may generate fiber concentrations requiring additional respiratory protection. Use the appropriate NIOSH approved respirator in these situations.

FIRST AID MEASURES

Eye Contact – Flush eyes with water to remove dust. If symptoms persist, seek medical attention.

Skin Contact – Wash affected areas gently with soap and warm water after handling.

Service Facts

W2 staging time delay options with single stage statThe auto mode can be used when employing a single stage heating thermostat. This mode allows the furnace to move into second stage based on the past three hour duty cycle of the furnace.*A furnace running in mild conditions will have a low duty cycle and a second stage delay of 10 to 12 minutes.*A furnace running in normal conditions will have an average duty cycle and a second stage delay of 5 to 7 minutes.*A furnace running in cold conditions will have a high duty cycle and a second stage delay of only 1 to 3 minutes.

Leave S7-1 & S7-2 to the off position when using a 2-stage thermostat.

The 50V51 Control board uses a 115 Silicone Nitride Igniter. This control board does not reduce the voltage to the igniter as other boards do. Do not use lower voltage igniters as replacement options. Only use the OEM igniter for replacement.

Fault Code RetrievalThe IFC has the ability to store fault codes in memory. To retrieve previous faults, push and release the last error button for 1 to 5 seconds. The LED will flash up to five stored fault codes beginning with the most recent. There is a two second delay between the faults displayed. The LED will flash two green flashes if there are no fault codes in memory.

Fault Code ResetPush and hold the last error button between 5 and 10 seconds to clear all faults from memory. The LED will flash three green flashes to confirm that memory has been cleared.

BK FeatureEnabling the BK feature is done through the S5-2 switch on the IFC. The switch comes in the de-activated “ON” position from the factory. Move this switch to the “OFF” position to enable the BK function of the board. Do not cut any jumpers on this board.The BK feature is used for blower modulation when us-ing a humidistat for de-humidification, a two step scroll compressor system, a 402 thermostat (with BK enabled), or residential zoning.A jumper must be placed between R & O on the low volt-age terminal board to engage the BK circuit
