10 System failure protection and code
Controller will judge various failures in system operation automatically and treats them accordingly subject to
failure types. Failure protection can be classified two types subject to failure reason and treatment method:
system recoverable protection and system serious failure protection.

Controller of HAC-FX-AUX
System recoverable protection
While air condition system recoverability occurs, whole system should adopt correlative protection
measurement.
After failure protected recovers to normal condition, system will recover to nomal condition.

AUX Highcool 2007 Series Fault Codes
In the event of a failure a fault code on the controller will usually advise the nature of the problem.
Fault codes are divided into two groups. E codes are major faults and require the system to be manually reset. P codes are minor faults and will reset themselves in the event of the fault condition resolving itself. Sensor Failure P codes will allow the unit to run in emergency mode for 50 minutes with limited functionality before halting operation if the failure is not cleared.
All fault codes should be investigated by an engineer, although Pr03 and Pr08 should be investigated by the user by cleaning the filter and checking the operating temperature first.
