I wired up one of these a few months ago and was also scratching my head trying to wire it up. Very basic instructions if I remember correctly.

We called the company rep who was very helpful and knowledgeable, and he talked me through it. I seem to recall that it was much simpler than I thought in the end, but unfortunately I can't remember now.

Hi the box connects to the boiler by two black cables with red plugs on in the back left hand corner of the boiler. This enables the boiler to have an input for cylinder. There then needs to be a neutral connected to this box but can remember what terminal. The ho****er control from time clock thro tank stat then this sw live goes in to the box. This is the hot water circuit control. The heating is wired from time clock thro room stat then to the other switched live in bolier near terminal block number 1 if my brain is fully working. Hope this helps
