It's possible to change a DeHaardt Range Extender or Timing Host to a different voltage (230v to 115v or vice versa).
You will need:
- Soldering iron
Then follow these steps.
1. Open up the box and remove the screws
There are 6 traditional screws on the circuit board, and 2 more black mounting plastics, indicated by arrows on the image below.
2. Flip the circuit board over
You'll need to work on the back side of the circuit board, so deconnect the cables and flip it over. The area you need is indicated in the image below.
In the example below, the circuit board has been configured for 230v.
3. Change the soldering
To change it, desolder the original connection, and solder the connections as indicated in red on the images below.
