    Hi All,

    Whilst having my kitchen updated the programmer accidently got broke from its back panel meaning i have to hold it together for it to work!

    I brought a Salus EP200 from ebay hoping it would be a straight swap however that isnt the case....

    This is my current box:

    L
    N
    3 - NO (HEATING)
    4 - NC (HEATING)
    5 - COM (HEATING)
    6 - NO (HW)
    7 - NC (HW)
    8 - COM (HW)

    L is Live but also feeds 5 & 8 Directly
    4 has nothing attached,
    Im also assuming the colour of wire means nothing for 3,6,7

    New box has this back plate:

    L
    N
    1 - HW OFF
    2 - CH OFF
    3 - HW ON
    4 - CH ON

    Do you have any ideas if it is possible to do a straight wire swap to the new programmer or will it need further work done for it to work?

    Thanks

    Ian
