Fireplace Control Circuit

Create a better and safer version of the fireplace. For the gas valve to remain on, all four sensors needed to output a registered flame. During field testing it was discovered that variations in gas pressure and humidity cause the thermal sensors to occasionally output no flame even when a flame was present. This caused frequent unnecessary shut downs and constant customer dissatisfaction. We need to install an indicator will be used by the service technician to diagnose whether a faulty sensor are present to see if a faulty sensor is present.

The main thing I would recommend to someone doing this project is turn the correct pins on in multi-sim to help avoid half the headache I went through. Otherwise just when you cut wires for your breadboard leaving a little extra to allow it to breathe a little, this will allow you to plug them in fully and not worry about wires not fully being plugged in which is far harder to find and fix.
