Got it, will give that a go

Thanks @JohnMo for the quick response So reason for the question is I found the mixer valve adjustment cap on the floor and reattached it thereby changing the setting I assume, have no idea what to adjust to or to be honest the theory behind it Assume the thermostatic value temperature is correct at 40 ?

Hi Would I be right in thinking that the gauge in the highlighted red circle should be matched to the blue highlighted Thermostatic Head temperature by using the blending valve ? Thanks in advance
