A likely cause of the excessively high temperature is the lack of inadequate convergence of the energy equation. Please try the "Stiff Chemistry Solver" that can be selected from the dropdown list under "Chemistry Solver".

The Temperature Threshold is to save computational cost by assuming the reaction rate is zero for temperature values below the threshold.
