Lifeless constructs shouldn't be able to utilize regeneration.
However, they are repaired if in a province with a lab ... so maybe what you observed wasn't the effect of the regen ring (that would only work during combat) but of being at a lab (what works turn-wise)?
Or did I get something wrong here again - don't think so but with DOM you'll never know
