When you slice an object the slicer normally defines temperature and sets it there. So you need to change the temperature in Filament description and reslice using that filament to get a new version with that temperature.
You should check in temperature view how high the output is. When you say 220 and it is all 100% and does not go over 200 that heater can not go higher. If it is not 100% then firmware is limiting it.
