When you start figuring out what these variables mean, it would be a good idea to create a table on paper, or speadsheet the same size as EC table 16 by 16 and cross out the regions that do not interest you.
For example, if you are looking for fan control, then you don't care about the variables that you know store battery charge information. Here is how I figured it out how to control the fan on TG: Nothing was found.
Found a few very brief remarks and incomplete guides. Gave me a general direction to go to.
