Fitting temperature stop concealed shower

[Matt0029]

How do you set this on a concealed shower cartilage is it ment to be so that when the shower is at its hottest the knob is at the 12 o'clock position. Then you have to press the button on to move it further. So the shower goes hotter then 38degrees c.

It's a a line on the splines wondered if this was anything to do with it?

Use a thermometer to set the temp before putting the dial on eg 38c set dial to 38c etc

It has a plastic over clip like this should it be lined up so you cant move it past 38c without pressing the button down?

Figures it out the stop on these are a total stop unlike a bar shower where you can press the button in at 38c to make it go hotter
