Dave, does your controller look like the one on page 14?

Yes - similar. It's called a Vitotronic 200 - the one with weather
compensation mode.

The external temperature sensor appears to connect to pin 1+2 on
connector X3 and not directly to the the Vitotronic unit so it
shouldn't make any difference.

The weather compensation kit comes with a replacement 'programmer' so
there must be more to it.

I have every faith that if you just find pins 6+7 on connector X3,
extend them to wherever you would like the control panel and reconnect
them, it should work.

I'm just curious about why they'd combine the DC with the data when
there's no need. And why the controller has a four pin connector.

The official manufacturers part would be nice because it gives you a
proper mounting but I can't see it being necessary from a technical
point of view.

The mounting and blank plate will certainly make things easy so I'll order
it up tomorrow.
