Request connection details of the Siemens central heating controller RWB2E?

There's a compatibility chart on page 2 of this PDF...

http://www.heatweb.com/pdf/Invensys/Programmer%20Compatibility%20Chary.pdf

It does not mention Siemens RWB2E but does show a Landis & Staefa RWB2E which I believe equals Siemens. It shows..

N = Neutral
L = Live
1 = H/W off
2 = C/H off
3 = H/W on
4 = C/H on

I would expect the voltage to be either 0V or 230V (in the UK) depending what the programmer is calling for.

Good luck...
