Thanks Ron, more question...if we set the PID to the manual mode,and we set the output % value to the any value, and in the same time we turn the potensiometer up and down, what's happend with CV, following values from potensiometer or value from that we set on the output % value? because as I knew in manual mode, output CV will follow from the value that we write in output % value.
And is it right function of tieback is use for bumpless transfer from manual to the auto mode to avoid any transient from manual to the auto mode?
