    I'm looking to replace my fixed boiler control unit with a wireless thermostat (so that i don't manually have to switch boiler on & off). Need some help in understanding how to rewire my existing control unit (Drayton LP111) with the wireless thermostat (Center BDR91). I've added all the images i have of the wiring. Hopefully i can get some help on this

    LP111 - BDR91

    Brown - L
    Blue - N
    Connect jumper wire from second L terminal to A
    If there is another wire in terminal 1 - also connect it to A
    Wire in terminal 3 - B

    If you have an existing wired thermostat, the wires will have to be linked.
