hi i would like to add a drayton programmer lp711, to worcester bosch 30 condensing combi boiler, any help with the wiring would be very much appreciated,
drayton programmer lp711
- Thread starter nello
- Start date
You don't say what model of Worcester Bosch 30 you have, so if the terminals described below which are for a 30HE don't correspond to what you have, please advise.
First of all, if there is a link between terminals Ls and Lr at the boiler, remove it, then connect the programmer as follows:
Boiler terminal Ns (Neutral supply) this should be connected to the N (Neutral) terminal of the LP711
Boiler terminal Ls (Live supply) this should be connected to the L (Live) terminal of the LP711
Boiler terminal Lr (Live return) this should be connected to terminal 3 of the LP711
Finally, link terminals L & 1 of the LP711 together

sorry about that it is a worcester 30cdi
That's OK, the terminals of the 30CDI are still marked Ns Ls & Lr, so the above connections are still correct.
