OpenTherm protocol: looking for schematics

Hi,

I'm designing a board that will have to embed the Opentherm interface.

The website www.opentherm.org doesn't say much.

I'm looking for schematics or hardware specifications.

thanks for any help,
Enrico

It says all you need to obtain the protocol: 
http://www.opentherm.eu/pages/protocolsummaryrequest.html

For that matter, it says you have to be a member of the association to 
sell products commercially -- and presumably if you're a member you can 
buy (or get for free) the full spec.

These two things are more or less orthogonal: the specs can be obtained 
free of charge.

The reason why the obtaining of the specs and the licensing are left 
separate is because a lot of the members of this industry may have the 
development of the electronics outsourced and this companies do need to 
become members (although it helps to be in).

hi,

thanks for your answer.

The protocol specifications (version 3.0) I got from the site don't
say much especially about the hardware interface.

It's a 20-page document and I guess they are just a brief summary of
the full documentation.

I browsed the web and couldn't find much, except: http://openingupopenthermprotocol.nl

Hi,

I also found this interesting datasheet: http://www.eu.necel.com/_pdf/U17475EE1V0AN00.PDF

It seems if you "must" use this protocol,  you need to be more closely 
linked to the openthern  community.


You may consider other open protocols like LonWorks etc.
