s plan heating system with pump in boiler not out side what do i do ?????

[lukesparky123]

Iv done a few heating systems now but no where near an expert yet but im a bit stuck because all the s plan systems iv done in the past have an external pump but this system is a vaillant boiler with an internal pump. So just need to know how to alter the wiring from external pump to internal.

any help would be great.
thanks alot luke

Manufacturers instructions should cover it. If it helps draw a box round the pump portion of your S Plan and have another look.

just delte wiring pump when stat opens pump starts in boiler,some boilers need perm feed for pump overrun (basically pump runs on for few minutes when no call)
