Braemar 628585 Smart Control (BSC) 4-5 STAR PCB

No Longer Available. Why?

Common faults:

  • False overheat fault (Code 10 or Code 19),
  • False ignition failure fault (Code 7),
  • False EFS shutdown fault (Code 11),
  • Incorrect thermistor temperature,
  • False thermistor faults (Code 4, 5, 15, 16),
  • Fan starts at full speed,
  • Fan speed not adjustable,
  • False condensate detected at start fault (Code 18).

Braemar Smart Control Fault Codes (4-5 STAR Models):

Code Fault Description
01 Pressure switch P-55 closed at start.  This fault is usually caused by a faulty Fenwal ignition module.
02 Pressure switch P-55 failed to close.

Check the following:
  • If the combustion fan does not start shortly after the thermostat is turned on (and the thermostat is set to a temperature higher than the current room temperature), there are two main causes:
    1). The Fenwal ignition module may be faulty.
    2). The combustion fan resistor may be open-circuit.  Disconnect the resistor and check the resistance of the resistor.
  • If the combustion fan does start shortly after the thermostat is turned on, but this fault code occurs, it may be due to a faulty pressure switch or condensate (water) buildup in the vacuum hose going to the pressure switch.  Disconnect the hose from the pressure switch end and blow through it to make sure it is clear of water or other blockages.  If there is water in the vacuum hose, the pressure switch may have a crack or hole in the internal diaphragm, and the pressure switch will need to be replaced, otherwise the hose will continue to accumulate water.  If the combustion fan is running and the pressure switch is working, the cause will most likely be a faulty BSC PCB.
03 Pressure switch P-55 open during run.  Check everything as per fault code 02.
04 Thermistor temperature higher than 70C during run.

Check the following:
  1. Check for air flow issues – too many closed vents/outlets, too many closed doors in the premises.
  2. Check that the return air filter is not blocked.  If fitted, it should be located behind the return air grille in the premises.
  3. Check that the room fan motor run capacitor is within 10% of its rated capacitance.
  4. Check that the fan blades are not clogged with dust and that the fan blades can move freely.

If overheating issues can be ruled out, the BSC PCB may be faulty.
05 Thermistor not connected or short circuit.

Check the resistance of the thermistor while disconnected from the BSC PCB.  The thermistor should measure around 3.3KΩ at 25C.  If the thermistor is shorted or open-circuit, replace the thermistor.  If the thermistor tests OK, then this will most likely be due to a faulty BSC PCB.
06 Over temperature switch OT4 open (5-star models only).  Check for overheating conditions as per fault code 04.
07 Ignition failure – Possible faulty/dirty flame sensor or false fault due to BSC PCB fault.

Check the following:
  • Ensure that all burners ignite during ignition.  If only some burners ignite, try cleaning the edge of the burner manifold closest to the heat exchanger with a small wire brush.  Be careful not to drop the brush into the heat exchanger.
  • Check that when the ignition module starts producing ignition sparks that the “GAS” LED on the BSC PCB is illuminated solidly, and is not pulsing or flickering.  If the “GAS” LED is off, pulsing or flickering, it will likely be due to a faulty BSC PCB.
  • If the burners ignite and the ignition spark stops within a second or so, you can assume that the ignition module is probably working correctly, and is not likely to be the cause of the fault.
  • If the Fenwal ignition module is producing sparks but the burners don’t ignite (or the gas valve doesn’t open), this will usually be caused by a faulty BSC PCB, however, there is also an over-temperature switch above the burners that has a manual reset button between the two terminals.  If this switch has tripped (open-circuit), there is a potential safety issue (rollout) and the heater must be serviced by a qualified gasfitter to ensure it is safe to use.
08 Condensate detected at start (5-star models only).

Check that the condensate drain is not blocked and that the heater is sitting on a level surface.

To troubleshoot models that use a condensate probe, try disconnecting the condensate sensor from the BSC PCB.  If the fault goes away, the heat exchanger may be full of water, or the condensate probe may be touching some debris inside the heat exchanger, allowing current to flow to earth, which will be detected as condensate.  If the fault persists with the condensate probe disconnected, the BSC PCB is most likely faulty.  Note that disconnecting the condensate sensor will not work on models that use a pressure switch for condensate sensing.

For models that use a pressure switch for condensate sensing, check that the vacuum hoses are clear of condensate buildup (water) and other blockages.
09 Internal memory failure – This is due to a faulty BSC PCB.
10 Over temperature switch HX OT1 open (tripped) – Can be a faulty over-temp switch or BSC PCB fault.  Check for problems that may cause overheating (refer to code 04).
11 EFS shutdown – The Fenwal ignition module has shut down or the BSC PCB may be faulty.

This fault can be produced by a number of causes.

Check the following:
  1. Clean the flame sensor.
  2. Ensure that all burners ignite during ignition.  If not, try cleaning the edge of the burner manifold closest to the gas jets with a small wire brush.  Be careful not to drop the brush into the heat exchanger.
  3. If this fault code occurs in addition to intermittent code 7 faults, this may be due to a faulty Fenwal ignition module or faulty BSC PCB.  If the burners ignite and the ignition sparks stop approximately 1 second after the burners ignite, the fault will most likely be the BSC PCB.
If the ignition pack is producing sparks but the burners don’t ignite (or the gas valve doesn’t open), this will usually be caused by a faulty BSC PCB, however, there is also an over-temperature switch above the burners that has a manual reset button between the two terminals.  If this switch has tripped (open-circuit), there is a potential safety issue (rollout) and the heater must be serviced by a qualified gasfitter to ensure it is safe to use.
12 Pressure switch P-100 closed at start.  This fault is usually caused by a faulty Fenwal ignition module.
13 Pressure switch P-100 failed to close.
14 Pressure switch P-100 open for more than 30 seconds during run.
15 Thermistor in cool location in duct – If the heater previously worked, it may be a faulty thermistor or faulty BSC PCB.  Check the resistance of the thermistor (refer to code 05).  If the thermistor tests OK, it will most likely be due to a BSC PCB fault.
16 Thermistor not installed in outlet duct – If the heater previously worked, the thermistor may be faulty, the BSC PCB may be faulty, the fan may not be running at the correct speed, fan run capacitor may be degraded.  Test the thermistor (refer to code 05) and then run through the over-temperature checklist to rule out airflow issues (refer to code 04).
17 Condensate detected during run – Blocked condensate drain, heater not level, faulty BSC PCB.
18 Condensate detected at start.

If this fault occurs on 4-star models that don’t have a condensate sensor, this fault is due to a faulty BSC PCB.

If this fault occurs on a 5-star model, refer to code 08 for possible solutions.  If no cause is found, the BSC PCB is likely faulty.
19 Over temperature switch HX OT2 open at start – Usually due to a faulty BSC PCB but can be caused by overheating issues.  Check for possible causes of overheating (refer to code 04).
