Kona, the P1 program is as follows:
C01 235 e01 F F01 195 (Box temp of 235, triggered by internal temp, to 195)
C02 140 e02 t t02 4.0 (Box temp of 140, for 4 hours time).
If you probe was exposed to box temp, it would have triggered the "hold" temp, step 2. Not sure if it was, just thinking out loud. When you put the meat in, do you remember what the readings were in the left and right windows? Left being box temp, and right being meat temp.
