this isn't hard
..but its got me down! .(.I rode the short bus to school /when I didn't have walk, uphill both ways!) I'm trying to get my reset ratio right it sayz 72 /72 on the paper work/pic....(btw 72 would be a miserably hot day) so lets say my outdoor temp for the next few months is going to be 10 degs or more like zero I figured 10' f is a lot closer to actual's, then 72 would ever be ! and my indoor temp > I have it set for 70 (wifes feet ) simplify the math to get to my reset ratio number ...beers to ya
