Title: Simple and likely a waste of time
Review: If you can wire a front and back doorbell with a transformer then you don't need this book to tell you how to wire hydronic controls. The control panels themselves will give you the same information in their installation notes and on the inside cover of the panel if you have lost the installation notes or can't find them online (as if). If you can't follow those instructions, you shouldn't be diddling with these things anyway.
