I live in an apartment with communally heating supply which is fed into a heat exchange unit in my apartment which uses the communal feed to heat hot water for taps and underfloor heating.
I have one of these v5012 things fitted which I believe regulates flow between input heated communal feed (rising right) and communal return (horizontal left), have tried to indicate in picture. This was recently adjusted when the unit was serviced, but we have a problem where the water does not stay warm enough. I believe adjusting this could help us achieve warmer water as this is what engineer previously adjusted, but apparently not to sufficient level.
Does anyone know is this something I can adjust myself without too much fuss? What do the numbers on the blue thing mean? Thanks in advance!
