Data Transfer Between PCB’s
If a new PCB needs replacing, you can transfer data (gas type, model type, gas
pressure and error history) from the existing PCB to the new one by doing the
following:
1. Check the current settings and note them on a piece of paper.
2. Adjust the dip switch settings on the new PCB according to the old one.
3. Unplug the power supply and remove the existing PCB.
4. Fit the new PCB and connect all the wiring harnesses
5. Ensure it is earthed correctly.
6. Connect the new board to the old board using the data transfer cable provided
with the new PCB.
7. Reconnect the power supply and push PB1 button of the new PCB.
8. The LED goes green: it means that the data transfer was successful. This will

10.
If the data transfer was not successful set the PCB manually according to the settings copied at the beginning of this
procedure. If manually set, the max and min gas operating pressures must be checked. Contact Rinnai UK if any assistance
is required.
