Watlow programming question
I am rewriting some programs on my furnace controller. There is an option " wait for process crossover value (WPr)" that applies to soak steps. Reading the manual it seems that this says wait until the previous step value / temp is reached before starting the soak. So if I am reading this correctly if step 1 is get to 500 degrees in two hours and then step 2 is soak for an hour Wif Pr set to true will only start the soak step after it reaches 500. If step 1 is 450 after 2 hours the soak timer won't start but once the furnace reaches 500, even if that is 5 hours later then the soak step will start. Is this correct? Many thanks.
