2 x new mira sport 9kw overheating

I have 2 new showers which seem to have good flow when on the coldest setting but when set on high and main dial turned up they both overheat. All valves are fully open. I suspect a pressure problem but am confused as there is good flow when cold.

As long as they are connected to the mains water supply then I would expect this to happen.

The shower should run properly with the temperature control normally just past the midway position
