    Hi so on a different thread I went through the steps to remove the maze and add a wiring center as follows

    Honeywell Cyl Stat - C,1,2 to Wiring centre C,1,2
    Correct

    Honeywell Thermostat - E, 1,2,3,4 - to wiring centre - E1,2,3 (no 4 in the centre) to just use the 3
    Correct; Terminal 4 is used for cooling applications

    Mid Pos Valvel - Grey, Blue, Orange, White to the same on the wiring centre (wiring center has a brown but Valve does not)

    Boiler just has E, N, L wires (as in the 3 of them) so in wiring center assume I just use L N and E
    Correct

    Live feed is obvious
    So it is

    L, N, HW On, Hw Off, CH On - to its counterparts in the wiring centre
    And so is this

    I use the Y plan (mid posn valves) so cut links L4 and L5
    Correct
    and I have read the boiler manual and it does not talk of pump overun anywhere so I guess I ignore that bit
    Correct

    So issue is the CH will not come on, the pump is silent and the valve does not operate when I use the room stat

    So I have bypassed the room stat by linking 1 and 3 in the wiring centre

    Still no good so its not the stat
    What tests can I do, can I bypass the programmer to HW and CH is just on all the time ?

    Help

    I think its the programme, I have bypassed it and made HW and CH perm live and now the heating is working and the hot water is on - I can control the heating via the room stat, hw been on all the time is not an issue

    Not sure how the pump, motorised valve all work together but if its working then I guess I dont need to worry about it to much

    Your obviously not getting a live from the programmer for the heating side.

    On the back of the programmer is a switch. Make sure it is in the P position, not the G position.
