Differential Temperature Controller

Former Member
Former Member over 11 years ago

What is the best way@ to control a whole house fan to run when the temperature outside is less than the temperature inside?

    Folks, does this really have anything to do with Single-Board Computers ? If not, then perhaps move it to a more appropriate area ? element14jamie might be able to help with that if necessary

    I would look for an SSR that features dual SCR rather than TRIAC output.  Except for rubber feet, I don't modify the box, just the lid.  I use calipers and a drawing program program to make footprints of where everything goes.  Then I print a sticker on a laser printer.  I check everything twice before I undergo the irreversible step of drilling holes.  If you can use roll-form taps rather than store-bought ones, you will have far less little shavings running around your box.  You might get away with slightly, slightly smaller holes than the tap manufactures recommend.  They are thinkin' Fe, you are using Si Al.

    Thank you!  As an old school programmer (Fortran, C, Visual Basic, ...) I thought someone might have an SBC solution for this application.  Looks like this "analog computer" is the way to go.  Thanks again, Don.
