sirrus 1850 running cold

I have just fitted a new thermostat and seal kit to my shower and it is still only running cold, hot water is getting to the shower under good pressure and if I turn the cold feed off it will go hot but as soon as the cold feed is back on it runs ice cold. any help would be much appreciated.

This cartridge runs best when the incoming water is balanced, and it would appear that the cold is overpowering the hot and needs to be reduced. There maybe a restriction in the hot elbow.
