Furnace bump timer

amdx · 2011-01-09T15:50:16+00:00

I put this circuit together over twelve years ago.I have it installed on my furnace/air condition control.I have a momentary switch near the thermostat, when Ipush the switch the furnace or air will come on for about4 minutes (plus or minus). I move an alligator clipdepending on season, you can put in a switch.I use it rather than turning the heat/air up and down,for a short comfort adjustment. It runs from a 9 volt battery and has very low standby current,about 80 nanoamps. The battery lasts two or three years. Others can modify for different purposes. If you think of anotheruse, please post it. MikeK

Yes. Other examples abound.

In a way, yes. I let the drill and the saw cut all the way through both paper layers and the 'rock.

It's fast and it works a treat.

A utility knife takes about 15 seconds start to finish. The scrap is in a couple pieces and is easy to clean up without power tools.

You can't fix stupid. You can't even put a band-aid on it, because it's Teflon coated.
