Every York Predator I’ve worked on with that same board always had about 15 million of those same stupid error messages which most of them don’t really mean anything. Yesterday I did a maintenance on about 15 older York Predators that predate that stupid board with the display. It was so nice. 😆
Simplicity boards suck! Some of those errors can be eliminated if they were disabled during commisioning the unit. The clean coil is stage 1 for C1, the other is for C2
