Product innovation
With its electronic control, the CEX 7-U ensures an energy-efficient hot water supply. The water is heated directly to the preset temperature as it flows through. The temperature can be selected at the touch of a button on the LCD control panel with two fixed value keys programmed at 35 °C and 48 °C at the factory.

  • 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
  • Two programming buttons for  individual pre-set ­temperatures, optional temperature limitation as well as function indicators
  • Adding cold water is no longer necessary
  • Easy installation under the kitchen sink facilitated by small dimensions and external ⅜" water connectors for closed-outlet or open-outlet installation
  • With power cable for permanent electrical connection
  • Remote control module available as an accessory: FXS 3 (C)
  • Can also be controlled by tablet or smartphone (from iOS 9 / Android-OS 4.4) (this requires an FXE3 (C) radio adapter and the "Smart Control" app)
  • Dimensions (height × width × depth): 29.4 × 17.7 × 10.4 cm
