Spider High-temperature and High-speed Hotend, Simple Installation, Wide Compatibility

Well it's working great at PLA temperatures but I bought this because it claims 500c capability, therefore I want to use it to print nylons on my ender 6. However, after installing the new hotend and thermistor, my ender 6 will still only go to 260c. Realistically I just need 290c to 300c max. But how do I get my printer to let me choose a higher temperature?
