Batboard

Does anyone know how to convert a astro w5 local to HHCH (w3)?
What would be required?
Cheers

You need the W3 HHCH obviously, and the W3 interconnect board. There are other small parts you'll need too, like rubber gaskets, the flange that covers the KVL port, and some assorted screws.

A W3 s-record would also be quite useful.

If you plan on doing an extended remote install, you will also need the control head extension cable.
