Hot tub controls operate in a difficult environment, where frequent splashing and operation with wet hands occurs. Traditional controls often consist of a panel with mechanical membrane switches under a waterproof covering with indicator LEDs or a custom segment LCD/LED display.

These controls can be improved by replacing the panel with a graphical touch display powered by EVE. This allows a wider range of controls to be provided as hot tubs gain more functionality such as lighting and audio, which can be easily customised for different models or updated in future, as we’ll as enhancing user appeal.

By designing in a colour touch display based on EVE, you can

  • Implement a modern and user-friendly graphical user interface
  • Display a wider range of parameters such as ‘set’ and ‘actual’ water temperatures
  • Support different languages and units (Centigrade and Fahrenheit for example)
  • Make controls more user friendly for lighting and audio etc.
  • Display warnings, messages and notifications more clearly
