Vaillant eCOTEC external control wiring connections

[CES]

Didn't know where to post this but if anyone is installing a "new" ecotec pro/plus then this may help if you are connecting an external room stat/ programmable room stat.

they must have had so many calls, ive rung them twice, about this. the instructions are not clear in the mi's
Actually i found the mi's very poor in parts, what we as installers need is a definative list for comisioning not refer to 3 chapters back then refer to table of codes page 67 or what ever
we need it in easy to follow format with the instructions to carry out the necessary test on the same page

I agree Steve. The Vaillant manuals were not really the best to begin with anyway. I got this after doing their one day ecotec course. Why they didn't include it in the installation paperwork I do not know.

the vaillant instructions are so full of whaffle getting to the info you need is just frustrating
