Hot Tub Controller

Overview

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 the future, as well as enhancing user appeal.

By designing 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, audio etc.
• Display warnings, messages and notifications more clearly

​Key Features:​

The following key features of EVE make it ideal for a hot tub control application:​

• Resistive or Capacitive touch screen options
• Custom Touch on capacitive models allows use of touch panels which can operate with water splashes
• Full colour graphics for creating a unique and eye catching user interface
• Comprehensive image support for background images, buttons and logos
• Touch screen support includes tagging/tracking for simple button, colour picker and slider implementation
• Low resource usage on the host MCU (ideal for adding a display to existing and new designs)
• Range of screen sizes supported including 3.5” up to over 10”
• Custom fonts allow multi-language support and symbols
