[QUOTE="Nick14, post: 520073, member: 34181"] Well there is a possibility, but I think the chances are very slim. So that’s why Im more focused on the electrics at the property. Honestly I really dont know. I’ve wired this without the pump connected, ive wired it up with NO neutral between the neutral wiring center terminal and the control neutral (that’s when I can take a reading of 180v at the control neutral at the same time Ive then checked the voltage at the neutral wiring central and get 0v. So the voltage is coming from the boiler control N. so simply I see it, it receives 240v on the R of the control terminal and 180v come back on the N. So to me It points to the boiler/PCB. They only other idea I could think of was the N on the main supply to the boiler has a loose connection somewhere and the coming out on the control N? Or would that never happen? If not what throws me is surely not 2 boilers? by the way thanks for your reply’s [/QUOTE]
