The control board in my furnace will not turn it on unless I manually turn the blower on. But when I do that the blower stays on until I manually shut it off.. So I built this to turn the blower on and off and also to override the thermostat.
I built this a while back out of necessity. I have not intended to make it an instructable so I did not do a step by step build. If you have any questions, please feel free to let me know, this is my first instructable.
