Removing tap from 3 dial 2 way thermostatic shower valve

[Aliciacluelessbuttrying]

I need to change the thermostatic cartridge in my shower valve, i have managed to take the other 2 taps off without any problem however the last one (the one that controls the temperature) won't come off, the only difference between this tap and the others is a little button that you press down when you turn it to get hot water.
I am not sure if i need to do something with the button to get the tap off or if i need to be a bit rougher with it. Has anyone got any ideas? ANy suggestions would be greatly appreciated

You need a water plier to twist the pointed handle with cloth protect from scratches anticlockwise, then need a hex allen screw depend on size anticlockwise or different ones bottom of knobs using thin screwdriver take off cover and then hex allen screwdriver
