Larry,
Sometimes it's less embarrassing to replace something rather than admit to an installation problem. This MAY be the case here. I think it's important to note that IOTA is not involved in the recall. I suspect if their product was proven defective they would be involved and would have to replace ALL suspect product. On IRV2 one person reported loose connections that resulted in the connector, not the relays, over heating. I have yet to hear of a relay failing; I just saying...
