Hi,

Can anybody offer any advice please?

I am installing my own simple central heating system - with just a
gravity fed DHW supply and a single pumped radiator system.

I am trying to figure out how to connect the 10/12 terminal box - The
only systems that have come with the contraols pack [from Danfoss
Randall] cover 2x2 ports and 3 port systems - I just need a single 2
port - if anyone could give me a bit of advice, please reply,

Best Regards

Gavin.
