control board that does nothing

[billygoat22]

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.

Those are 2 relays on the board. What is a board PN?

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

Hmmm looks like more than three sensors.

Only thing I can imagine .... it could turn off the strips now n then ?

IF hooked up correctly

What did those sensors monitor ?

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.
