P.C.B. & R.D.S. (Removable Data Stick)
The same P.C.B. is used for Combi and System models.
The R.D.S. is a removable data stick that determines the model type and also gas valve settings for that particular boiler. The
P.C.B. will not work without the R.D.S. and the display will be blank.
The R.D.S. will store in its memory the Calibration settings for that particular boiler and also the boiler type and output.
If changing a P.C.B., simply swap the existing R.D.S. over to the new P.C.B.
If the R.D.S. is damaged and a new one fitted then a Calibration is required (go to page 11) to calibrate the system.
