Have successfully installed 3.0 Extreme and is working fantastic. However I would appreciate an idea of what the icons mean as well as some assistance with manual settings. i.e. what is too fast or too slow for the pump as I do not want to over stress it and same applies to the fan speed? and how do I set the speeds, acceptable temps etc. I have to say that lack of even a simple manual, even an on line manual, is a tad disappointing for what is a great product.
