Auto fill and flush Gas Furnace

1 IC chip, 1 Button, 1 Dial, 2 Volume Pumps, 1 Gas Mixer, 1 Gas Furnace​.. This is the first chip you will need, and it will control the input of gasses to a setpoint by pressing the activate button on your wall. Once it has filled, The Furnace will auto ignite. I have my input gas mixer set to 70/30! For the full automated experience, you will need the entire collection found below. Note: My N2 gas for flushing the furnace is always cooled below 20c, and if your gas is not that cool, change line number 66 to whatever temp you would like to close the N2 (nitrogen) pump. You can have the dial in any position except number 6, as that is the flush setting on the dial. Inputs on the Chip: D0 = GasFurnace D1 = Mixer D2 = OutputVolumePump D3 = Button D4 = Dial (set max 6) D5 = N2 VolumePump The dial will have 0 - 6 if you use all the IC chips.. 0 = No auto control 1 = steel , will need the Steel auto control IC download 2 = electrum, will need the electrum auto control IC download 3 = Invar, will need the Invar auto control IC download 4 = Constantan, will need the Constatan auto IC download 5 = Solder, will need the Solder auto IC download 6 = Flush, will flush out the furnace with Nitrogen (gas of choice), and cool it down. Be sure to get the entire collection of IC's for the full furnace build: https://steamcommunity.com/sharedfiles/filedetails/?id=1542347661 Folow the alias names to know which pins go to which devices, and it should be all good to go. I hope there are not any bugs I have not found yet. This is a work in progress. Want to see it in action??
