The on/off adjust are normally left as zero (the default values). You are right that these parameters can be used to fine tune water pressure / reducing hammering problems. I frankly don’t know what are the rule-of-thumb values. I think (I am not an expert on this topic 🙂 controllers that do not provide this as an option just use zero.
