What you want to do is to decouple your water molecule, that is scale all non-bonded interactions between your water molecule and the environment while preserving the internal bonded and non-bonded (water doesn't have any) interactions. All you need to do is to set both ti/scmask1 to the water molecule in question and ti/scmask2 will both be an empty string.
