Please Note:  This is the new ZA3P, which replaces the ZA3 - the board has extra inputs and 

functions.  There are some minor changes to the wiring and dipswitch settings, but retains all 

functionality of the ZA3 PCB.

This circuit board is a replacement for repair purposes. Please note, despite the image, this product does not come with connectors. Use the connectors in your existing installation.
