12.6.2 When a fault is present, controller gives an alarm and fault module number glistens. Pressing the
query key now can show the fault code and the fault can be resolved automatically.
12.6.3 After the fault is resolved, the indication of a serious fault will still display, only after pressing the
“reset/dark” key will the system return to operating condition before the fault occurred. As for restorable
faults, such as temperature sensor fault, when the fault is resolved, the unit restores automatically.
