I have to rejig my plumbing to get the VRV to stay closed by getting more pressure on the return side .
I should be able to put a valve on the return solar pipe before it goes to the normal pool returns BUT.....
I have notice that the deep reurn in solar mode is not working , when I block one of the surface returns air will start coming from the deep return .
So I wish to put a two way actuated valve at the spot shown to direct all the water to the deep end . This valve will operated with the solar valve .
This give me enough pressure to close the VRV direct warm water to the bottom where its coldest and when solar is not on the VF intelliflo will still have it full flow .
I want to do this in solar only mode , I have a intellicom2 to operate the VF on external control so I use the VF menu instead of scrolling thru the Suntouch menu .
Can this be done / can I use Valve A or B in Solar only mode .
