P.C.B. & R.D.S. (Removable Data Stick)
(Fig. 64)
NOTE:
Both P.C.B. and R.D.S. are available as spare
parts. The P.C.B. is suitable for any boiler model. An
R.D.S. specific to the boiler model output & gas type will
be required if the R.D.S. from the original P.C.B. is not
being transferred. It is recommended that P.C.B. and
R.D.S. are replaced together.
1. Ensure that the power to the boiler is isolated and wait
10 seconds.
2. Remove the screws securing the control box cover and
release the cover retaining barbs from their slots.
3. Note the position of all plugs and wires on the P.C.B. and
disconnect them.
4. Undo the securing screws and remove the P.C.B.
IMPORTANT:
If only the P.C.B. is being replaced
transfer the R.D.S. from the original board to the new
one. Where both P.C.B. and R.D.S. are being replaced
ensure the new R.D.S. is on new the board.
5. Reassemble in reverse order. Ensure that the ignition lead
is connected correctly.
