Hi,
I have purchased a new Viessmann 100-W WB1B 26kw open vent gas condensing boiler , viessmann reccommend it ideal for `y` and `S` plan systems and i 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 2 timed 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 14 says remove jumper x1 when connecting a room stat (assume remove link between 1 and L) page 42, of the installation manual shows 3 possible room stats but it is not clear if these are timed outputs when the timer is fitted.
Connection 5 shows two wires 9 and 10 and on the boiler these are two fly lead connectors both marked 5 for cylinder damand but again are these timed? 24vdc? 240v? or do they just need to be closed to make the boiler run, if they are timed 24vdc i can fit a 24vdc relay.
Thanks for the earlier reply, but there is no terminal block 96, that may be on another model, no frost protection is required and this boiler does Not need pump overrun, i just need to know the 2 timed output channels and what makes the boiler run when the programmer is fitted.
Thanks anyone, or if you have a link to viessman technical.
