UPGRADING YOUR CONTROL PAD
When replacing control pads you MUST replace with the same pad as the connections from the pad can be different to those on the steam generator or electronics. Additionally the data communication to and from the generator must correspond (think of it like pointing a television remote at a different Make/Model of television, the remote would not control the television correctly)

If you wish to upgrade your control pad to a later generation, then you MUST purchase a corresponding steam generator system. This may require modification to the tower panel of your shower to house the control pad that may be a slightly different shape or size.
