simple math help ,with 4way valve/outdoor reset pic!

[atvalaska]

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

So whats the supply temp?

If Im reading this right.. assuming a supply temp of 140

140-72=68
72-10=62
68/62=1.09 or rather 1.1

boiler supply is 180 to the 4way ...i have the 4way valve set to knock the supply temp to the.... none/110.... at the manifold

I would think that the are referring to the manifold supply temp 110 but I don't know. I am sure that someone here does...

Assuming that they want the supply at the manifold temp...

110-72=38
72-10=62
38/62=0.6
