ideal isar boiler

[carl150]

Hi just replaced the pcb on my ideal isar boiler the problem is H 5 is flashing up no hot water or heat ! Looked on a few sites and they talk about jumpers if these are the connection that push in then they all seem pushed in. Any replies would be greatly appreciated. Thanks

Have you used them into the right jumper pins though? Those PCBs do several different boilers and need setting up accordingly.

Hi Dan no haven't set up the jumper pins , just bought replacement box of E Bay. Any ideas how I would set them up ? Thanks

 

[Dan Robinson]

By reading the pcb manual and cross referencing with your specific boiler.

We had no manual Dan with the pcb . The chap of ebay must have sold 40 + all with positive feedback I thought it was a case of swapping over. Which pins need setting up ?

 

[Dan Robinson]

It depends. That's why there is a manual. Probably also why these things are going on eBay cheap
