keyword=HPH for loop3Reduced the flow for loop 3 down to 100W, after some time the flow suddenly drop which caused the target temperature to rise. Get the flow back, now HPH is around 220W. It seems that the flow is not stable when HPH is below 100W, and the feedback from the change of JT valve may be slow. Keep the step size at 0.5!
