This is simply amazing product!!! You can change the cold water and hot side blue and red sign by simply take the plastic out and rotate it the way you need to display the water temperature , the is is useful if some cowboys installed the cold and hot pipes wrong like in my case , and in tha case the termostatic shower mixer won’t work and that’s why you’ll have to go for a manual shower mixer and that will fix the problem without having the needs to replace the pipes where in my case are in the wall under the tiles !! Hope this helps !!
