You won't get a your desired carbonation level force carbing at room temp. There are calculators out there that will help you determine where to set your regulator at a certain degree.
If you natural carb I would set the lid by hitting it with 20-30 psi then disconnect the co2 an turn down to 12. Purge the 20-30 psi to remove the oxygen from the head space and connect the gas again and purge the head space by pulling the relief valve a few times for a few seconds then take the gas off and let it prime for a few weeks. All this of course after adding the priming sugar.
I have not yet tried the natural carbing in a keg but have been planning on trying it because my keg fridge recently has been used as a fermentation chamber.
