In the the "History of Ghl" article referenced this (https://www.aquariumcomputer.com/me....rch-institute/) from the website.
It talks about using the Dynamic Value feature to vary temperature throughout the day, and other things, I have looked through the advanced programming module for the P4, and other manuals and nothing references how to do this. So I thought I would ask, how do we do this?
Thank you
