Well the boiler got installed and eventually the electrician returned to
wire up the system.

Without much thought or any advice, I had opted for W plan. The circuit
diagram looked simple enough:-(

Using heatmiser manifold controls is not at all simple. Basically they
don't tell you what is inside the box only a dumbed down version of what
to connect to which terminal.

After several hours of try this, try that, the electrician claimed to
have a working set up and went home.

I have not yet had an opportunity to check:-(

Anyone done this? Or pointers to some suggested arrangements?
