Precise hot water
convenience .
The CEX-U’s electronic controls ensure an energy-efficient hot water supply. The water is heated directly to the preset temperature while flowing though the unit. The temperature is selected by pushing one of the buttons on the LED panel, with factory settings programmed at 35 °C and 48 °C.
- Electronically controlled instant water heater in compact design for installation under the sink
- Push-button operation panel with LED display for precise temperature setting between 20 °C and 60 °C
- In the comfort zone between 35 °C and 43 °C, the temperature can be set in 0.5 degree increments
