Undo a couple screws, remove old unit and pop this into place. Doesn't require any plumbing skills, no need to replace the whole zone valve body unit. Second failure I've had with the electronic box on the zone valves in my home. But, I guess with 5 zones valves over 20 years that is reasonable reliability. I think I'll order another to have just in case I have another winter breakdown.
