I had one of those on an O-200 and Jeff is right, there are 4 CHT/EGT channels in total (plus two more for oil or water temp and oil pressure). I had mine hooked up to monitor EGT and CHT on cylinders 1 and 4 on the basis that the other two cylinders were likely to be in between whatever temps I was seeing on 1 and 4.
As I recall, the unit can be used for any combination of CHT and EGT ranging from 4 EGT and 0 CHT to 0 EGT and 4 CHT. I had some difficulty getting the tach function working right, but it was always solid for temps.
