Mira excel shower

We have just had a new central heating boiler installed (open vented) with tank in the loft. However, the shower now only pumps luke warm water and the temperature will not adjust to hot or cold.

Can you please advise on whether there is problem with the central heating installation or do I need to change the cartridge?

Try resetting the back of the cartridge to the high pressure setting.
