Vulcan Gas Ducted Heater Fault Codes:

Fault Code	Fault Description
0	No faults present in the fault log.  This would normally be seen only on digital remote controls/thermostats that are connected to appliances that are fairly new or that have never logged any fault codes.
1	Blocked Flue.
2	Pressure switch fused closed.  The electronic control module is sensing that the combustion fan pressure switch is closed-circuit when it should be open-circuit.  The pressure switch may be faulty, but in most cases, this will be caused by an electronic control module fault and the control module will need to be repaired or replaced.
3	Combustion fan or combustion fan pressure system fault.  The combustion fan pressure switch has opened during operation.  If the heater has run for approximately 10 seconds and then shuts down with this code, it is likely that the thermistor is faulty (shorted or disconnected) or the control board has an electronic failure.  The thermistor is usually a small green electronic component located near the hot air outlet of the ducted heater.  The thermistor is only present on modulating heaters (4-5 star).  This fault can also be caused by a loose connection somewhere in the pressure switch wiring.  Note that these heaters run the pressure switches at 240V AC, so the heater must be switched off and unplugged before any diagnostic or remedial work is performed.
4	Supply Air Over-temperature.  The over-temperature thermostatic switch near the hot air outlet of the heater has tripped.  The heater may be overheating, the over-temperature switch may have failed or there may be a loose connection in the wiring going to the over-temperature swirtch.  Check that the switch has continuity with a multimeter when the heater is cool/cold and that there are no loose connections.  If no fault is found, the issue is likely related to poor air flow through the heater. If air flow issues are suspected, check the following items: Check that the return air filter is not blocked (if installed, it will most likely be found behind the return air grille). Using a multimeter, test the capacitance of the room fan motor run capacitor to ensure it hasn’t degraded.  The capacitance should be within 10% of the rated value (uF/MFD) printed on the capacitor. Check that the room fan motor has not seized and can rotate freely. Check for excessive dust build-up on the room fan blades. Check that there is no collapsed/crushed ductwork. Check that there are sufficient registers (vents) open in the premises. Check that there is no air flow obstruction in the premises (eg. closed doors preventing air reaching the return air vent).
5	Electronic malfunction.  An electronic malfunction has been detected in the control module.  The control module will need to be repaired or replaced.
6	The control module has detected that the gas valve is slow to close.  This can be a real fault (faulty gas valve) or a control module fault.
7	Ignition failure. Check the following: Clean the flame sensor.  Remove the flame sensor from the heater and clean it with a wire brush or sandpaper. Check that the gas supply to the heater is turned on. Check that the burners are all igniting after ignition.  If not all burners ignite, try cleaning the edge of the burner manifold closest to the gas jets/nozzles with a wire brush. Check that there is an ignition spark present when the gas valve opens.  If there is no ignition spark, the control module will need to be repaired or replaced. Check that the gas valve is opening.  In most cases you should be able to hear or feel the gas valve open, or check for the smell of unburnt gas near the flue.  If the gas valve isn’t opening, check that the control module is supplying approximately 240V AC to the gas valve during ignition.  If there is no output from the control module, the control module has failed and will need to be repaired or replaced. If the burners all ignite and then the heater shuts down with this fault code, check that the flame sensor has continuity from the flame sensor terminal at the control module and the tip of the flame sensor.  If there is continuity, the control module flame sensing circuitry has likely failed and the control module will need to be repaired or replaced. 5-Star models: Check for a blockage in the condensate drain or flue.
8	Gas interruption.  The control module has sensed that the burners have lit and then extinguished unexpectedly. Clean the flame sensor using a wire brush or sandpaper.  If the problem persists, it is most likely a control module fault in the flame sensing circuitry.  On 5-star models, this fault may also be caused by a blocked condensate drain or blocked flue.
9	EEPROM failure.  This is an electronic malfunction and the control module will need to be repaired or replaced.
11	Communication failure (wireless remotes).  This fault mostly occurs when a wireless remote control is controlling the heater and then goes out of range.  Try replacing the batteries in the remote control or keeping the remote control closer to the heater.  It can also be caused by a faulty remote control transceiver module, or a damaged communications cable.
12	Communication failure (touchpad controller).  If the heater was working previously, the most common reasons are either a damaged communication cable or faulty touchpad controller.  The touchpad controllers can fail, usually due to an electronic component leaking electrolyte onto the circuit board.  The electrolyte is corrosive, which damages the circuit board and surrounding components.  If the communication cable is not damaged, the touchpad controller will most likely need to be replaced.  Due to the corrosion issue, the touchpad controllers aren’t generally repairable, and any repair won’t usually last long.
13	Security Lock.  This is usually the result of an electronic malfunction of the control board, which has caused this feature to activate itself.  This feature was intended to be used by installers, so that appliances that have been installed, but not paid for, can be locked by the installer until payment is made.
14	Unreadable/scrambled EEPROM. This is an electronic malfunction and the control module will need to be repaired or replaced.
15	No fault present.

Terms & Conditions – Repair/Exchange:

• All products come with a standard 12 month warranty, that can be extended at the time of sale.  Extended warranties are available at a rate of $44.00 per every additional 6 months.  The warranty period is limited to a maximum of 24 months.
• The warranty covers all parts used in the repair as well as the labour provided by LOGISENSE.  The warranty does not cover the labour of yourself or any third party.
• The warranty does not cover damage caused by faulty accessories, power surges, lightning, water ingress, wiring faults or incorrect installation.
• The customer pays all postage costs (where applicable) and should ensure that all items posted are adequately protected with bubble wrap or similar.
• Items that have been tampered with (eg. items that have been previously repaired/worked on by yourself or any 3rd party), cleaned with chemicals, damaged by water/liquid/moisture ingress, fire, power surges/spikes, lightning or that are in otherwise poor physical condition are not eligible for exchange, but a repair may be offered depending on the extent of the damage.  Items that meet this criteria need to be assessed on a case-by-case basis and may attract an additional fee, as they typically require more labour and components than usual to complete the repair.  It is also possible that the repair request may be declined.
• There is an assessment fee of $44.00 if the item you bring/send for repair is not faulty.
• There is no charge in the event that the repair is unsuccessful or the item sent in for repair is deemed to be unviable to repair, other than return postage (if applicable).  Such items can be disposed of via e-waste recycling.
