Hi all,
I've been asked to wire up this new boiler which is on an existing y-plan system. It should be a simple case of giving it a permanent live...apparently. However on the existing y- plan the over run pump ( in airing cupboard) live comes off the oranges, which I believe to be the s/l... So I've taken a perm live to 230v term at boiler easy bit, then separated live to pump at wiring centre away from oranges and gave a perm live(refer to 3rd paragraph)
I know end result should be LP is live to pump... Np is neutral to pump then lr is S/l from oranges.
The existing cores being used at old boiler was s/l and N with a spare core so used this temporarily to attach on to separated pump live to give perm live and at boiler term LP believing that LP is automatically linked as a perm live within boiler this should give the pump its perm L and use the neutral within wiring centre.
The problem I have is that the pump is not cutting out after 5 mins why? Is it a case of wiring as I know the end result to be?
New to y- plan any help would be great.
