⚙️ Functionality

The Duoetto MK2 heats and stores 10 litres of water using either a 12V or 240V power source. On 12V operation, the digital controller allows accurate temperature selection up to 70°C. On 240V power, the thermostat offers a wider adjustment range up to 75°C for higher-demand use.

Automatic voltage detection switches between power sources without user input, ensuring continuous hot water availability. Integrated safety systems protect against over-temperature conditions, pressure build-up and dry operation.
