QUOTE One thing that is bugging me though. Why do my photos always get reduced in size??

A worthwhile question. The reason is that you are uploading the images directly to the post as attachments. These appear in the post as thumbnails, hence the reduction. If you want the photos to appear in the post itself, you are back to having to upload the images somewhere on the internet and reference them via a URL but as a Plus member you can upload the images to a photo gallery in the Forum and fetch them from there. That's what I do. I think this is more flexible as you can use the photo again in the future in another post. In the case of illustrative photos such as the ones you have just posted, you are almost certainly going to use them again, as someone will ask a similar question.

I hope this helps.

QUOTE It does indeed David and I will now place photos in my album, before posting them into a topic.

Thanks very much.

You're welcome.

I should have added that you can see the attachment at its full size by clicking on it, but you all knew that didn't you

Model Signal Engineering (MSE) stock the Viessmann mechanism to go with their kits, so yes it is. They have quite a selection of operating mechanisms listed on this website page
