Hi, I have purchased a new Viessmann 100-W WB1B 26kw open vent gas condensing boiler and want to connect it to my existing `S` plan system using cylinder and room stats with Honywell zone valves. I have also brought the digital 2x channel timer. The pipework is stright forward but i cannot see where the switched 240v lives are connected from the boilers control panel to feed the stats/valves and the live return to make the boiler run?? or am i missing something? The wiring connection page 42 of the installation manual X1 shows 3 possible room stats but it is not clear if these are timed outputs and it has a capacitor and a link across the terminals are these removed? Connection 5 shows two wires 9 and 10 for cylinder damand but again are these timed, do they just need to be closed to make the boiler run and if so how does the cylinder stat get 240v to make the valve operate?? Any help please.
