Very much appreciated. Thanks for bearing with me!

Ok thanks, Jim. I'll give it a go in the morning and see if I can make any headway. Much appreciated.

I've posted a few photos of the transformer and the EIM. I wasn't exactly following your lead ;) I'm a carpenter by trade so bear with me. Can I run an 18-3 wire from point A to point B to accomplish the goal? Thanks!

Hi, I would appreciate any help on this. I have a 130 yr old house with a 5 yr old Buderus boiler running 3 zones. Two of the zones are fine and working on basic stats. The 3rd zone (upper floor) had a new wire run during recent renovation (by me) and I have since discovered that the wire is...
