What this code means

This alarm occurs when there is a short circuit on an on/off valve coil.

Applies to: ZAPI ACE0 / COMBIAC0 controller.

Possible causes / checks (from the source)

A) If the fault is present at start up, it is very likely that the hw overcurrent protection circuit is damaged, it is necessary to replace the controller. B) If the fault is present when the controller drives the outputs, the problem is located in the harness and in the coils.
