I have the following setup. Is there a simple(ish) process for setting up the pump speed and bypass valve settings? Would you first set the pump speed and then adjust the valve to suit the pump speed or does it not matter? Is a lower speed better than a higher speed? Why are there different speeds - why not just one? Should the bypass valve need readjusting if you changed the pump speed - presumably there’ll be more pressure to open the valve at higher pump speeds so should the valve be tightened a little? Or loosened off on a low speed?
Another question, is it common for the valve to make a noise when it opens? The reason I ask is that after I have my shower go to bed at night, about 15 minutes later I hear a funny one-off farty/groany squeak. I just got the exact same noise when I loosened off the valve so I assume the noise that I’m hearing is the valve opening when the hot water has reached temperature, the zone valve closes and the pump overruns. Is that normal or does the bypass valve need changing - it’s only about 15 months old. Or is just good old trial and error. Thanks.
