Deltasol relays help to identify which is which

[wbuchan]

Hi,

Can you help identify which relay is which in the following photo please.

There's a simple white one - schrack v23092 a1012 a302

and, I think, a more complicated looking one - resol r-ssr [10]

Which controls the solar variable speed pump?

Any help much appreciated.

Thanks,
Walt
