Breezair Fault Codes:

Code	Fault Description
01	Communications problem. Check the communication cable between the wall control and cooler for damage.
02	Water not detected at the salinity probes. The water supply to the cooler may be turned off, the solenoid valve may be stuck closed and not allowing water into the cooler, the salinity probes may be faulty, the drain valve may be stuck open or not closing (cycling open/closed), or the control module salinity sensing circuitry may be faulty. If you receive fault code 2 within 10-15 seconds of turning the cooler on, then the control module is faulty.
03	EEPROM failure. The control module stores a small amount of data related to settings for the operation of the cooler. If this data becomes corrupt, you will often receive fault code 3. The control module will need to be repaired.
04	The cooler has failed to drain the water from the tank/sump. After waiting 4 minutes for the water to drain, water was still detected by the salinity probes. This suggests either a faulty drain valve (not opening) or a blockage in the drain pipe.
05	Not Documented / Probably Unused.
06	Not Documented / Probably Unused.
07	Mains power supply frequency is incorrect. In Australia, we have a nominal 50Hz power supply frequency. Fault code 7 will be produced if the mains frequency is outside the limits of 46-54Hz. This can be caused by contamination to the circuit board inside the control module (eg. spiders and other insects), generators, a loose/bad connection at the power entry connector or other internal faults. Electrical arcing on the cooler circuit in the premises may generate this fault as well.
09	A brief power failure has been detected.  This fault isn’t displayed as a service code but it’s stored in the fault log inside the control module.  It isn’t anything to worry about in general.

You can determine if a fault is being reported as the wall control (thermostat) should report this when the cooler shuts down due to a fault.  While on the roof, you can still determine if a fault code is being reported by looking at the “DIAG” LED on the front of the control module inside the cooler.  The “DIAG” LED will turn red and flash a number of times with a longer pause between the sequence of flashes.  Count the number of flashes between the longer pauses to determine the fault code.

The “DIAG” LED indicates normal operation by continuously flashing two green flashes between a longer pause.  Do not mistake this for fault code 2.  As mentioned above, the “DIAG” LED will flash red when it is flashing a fault code.

A long green flash means that the command has been received and the cooler should act on the command.

All troubleshooting should be done with the wall control in MANUAL mode.

Note that there aren’t any fault codes for the fan, as there is no way for the fan circuitry to communicate faults other than by flashing LEDs on the front of the control module.  A common fault of these control modules is that everything works except the fan.  To determine if it’s a control module fault, put the cooler into MANUAL and VENT modes and then check if the “POWER” LED on the front of the control module is illuminated.  If it’s not, then the control module has failed and will need to be repaired or replaced.  If you hear the fan motor buzz, groan or occasionally make a clunking noise while the fan is running (one initial “clunk” at startup is normal, but repeated random clunking is not), turn off the cooler immediately and call us, as this is often a sign of a short circuit in the fan motor windings or a damaged inverter module inside the control module assembly.  Continued attempts to run the fan will usually render the control module irreparable.

SAL (Salinity LED) Fault Codes and Status Information – MagIQtouch Models:

Flashes	Fault / Status Description
1	Normal Operation.  Water has been detected at the probes and the salinity is within the set limits.
2	Salinity above the set point.   The cooler will drain some water and re-fill shortly.
3	Salinity control is set for timed drain.  The cooler will periodically drain water to keep it fresh rather than using the salinity probes to determine if the water should be refreshed.
4	Operating without a drain valve (aka. bleed tray mode).  This mode is used when the cooler is set up to permanently hold water and periodically drip water to keep the water from becoming too saline.
5	Thermostatic control operation (no water).
ON (Solid)	No water present or unable to detect the presence of water. When the cooler is in vent mode (fresh air, no cooling) this is normal. When the cooler is in cool mode, the inlet solenoid valve (if fitted) should open and fill the base of the cooler (the tank) with water.  If the solenoid fails to open, the SAL LED will be on solid and you will eventually receive fault code 2 or the DIAG LED will turn red and flash a 2 flash sequence repeatedly. If the cooler is full of water and the salinity probes are immersed in water, then either the salinity probes have failed or the circuitry inside the control module has failed.  The probes can be tested with a multimeter in continuity mode or resistance (Ω) mode.  Each terminal on the bottom of each probe has its own wire.  Each probe should have continuity to one of the wires at the plug on the end of the lead.  Occasionally the probes go open-circuit or high resistance inside the probe assembly, in which case they need to be replaced.  The resistance of healthy probes is typically less than 1 ohm. If the salinity probes test OK and the terminals on the bottom of the probe assembly are immersed in water, but the SAL LED is still on solid, the control module has likely failed and will need to be repaired or replaced.
