New here for forgive me if my search didn't turn up the answers. I've got 2 York Predator RTU's with Intellicomfort and the simplicity linc boards. Have been having an issue where one unit will stop mechanical cooling and throw a code 129 (pulled via some monitoring software over bacnet and simplicity linc). I can't seem to find any alarm codes greater than 43. Anyone have any links or ideas on what a code 129 is? Or does York protect that information and limit it to authorized dealers? Was hoping to have a general idea before the vendor gets out here to investigate.
