d2 is the code symbol for delay after central heating. and is not a fault code.. however if this is coming on then stopping the operation of the boiler then it usually points to a sticking diverter valve.

Setting time is not in manual that we received, however, we did get a separate sheet:
Buttons top left-right are
A - Clock adjustment
B - Operating Mode selecting
C - Override
Buttons bottom left-right are:
D - -
E - Programmes
F - +
To set clock: 1 - Push A 2 - When the DAY and the CLOCK icons on the LCD are flashing use + and - (D and F). You should set the day of the week (1 = Monday, 7 = Sunday). To confirm the day press A. 3 - The HOUR and CLOCK are flashing use + and -. Confirm with A. 4 - MINUTES and CLOCK are flashing use + and -. Confirm with A.
My LCD is not working correctly, so I have to press the screen gently to see what icons are displaying. Annoying.

there is just two screws holding divertor valve in remove these screws (do not touch painted screwheads) then twist left to right and pry gently were the two screws were fitted. best bet is to replace diverter valve head to stop noise
