Then when I go back to the setting I then select the boiler control and select wireless relay box and it asks me to bond it again. So I'm presuming this is where the double bonding comes in. I have played around with different selections and at the moment I have got it back to square one where I am getting a boiler relay fault coming up but at least the heating is not coming on with the water.
