horizontal crosswater shower/bath with 3 controls

The central control has a red button. Shower is too hot, bath side unable to get cold water. Is the thermostat a CP0000250 or a a GP 0000250? Are these interchangeable? System bought from Bathstore about 5 years ago.

First check that the cold check valve at the shower is not blocked or the filter on the cartridge is not blocked.

CP0000250 and  GP0000250 are the same part, the manufacturer just changed the first two letters.
