As per subject, is there any definite way to check that regenerator is working and not in pass through?
I own older P3 and reason I am asking, I no longer notice sonic difference between multiwave (MW) and not. Additionally, in the past MW mode used to show drop in wattage, but now both modes show same consumption. When toggling between the two, I notice a temporary wattage drop, but it returns to same value. In other words, both modes show same consumption. To be precise, MW mode showed about 100W consumption and normal about 120W idling.
However, when I login to the web interface, I do see THD out lower than in. Still not sure it works correctly as before. Could someone please advise?
Thanks in advance
