    control board that does nothing

    had a customer want this removed from unit. tennent had sold him one to save power somehow and saw no difference, so asked me to take it out.

    there was no way for this board to control anything, since just wired to the tstat connections in ah, not breaking any connections. had 3 sensors.

    don't really see a pn, has some randon looking numbers in one corner, but thst's it. 0521, ptc-1v-0, or 94v-0 take your pick.

    the only tstat connections are y,c,w2

    So, all it does is turn on and off a red and green LED. That is brilliant!

    A few random parts on a circuit board that is sold for 20x the cost to produce.
    It's an upside down world we live in.
