Description of the appliance

The E-convenience instant water heater DEX Next S is a fully electronically controlled instantaneous water heater graphics-enabled e-paper display and sensor keys for a convenient and efficient water supply to one or more tap outlets.
Its electronic control regulates the power consumption depending on the selected outlet tem-perature, the respective inlet temperature and the flow rate, thus reaching the set temperature exactly to the degree and keeping it constant in case of pressure fluctuations. The required out-let temperature can be entered via the sensor keys within a range between 20 °C and 60 °C and can be read off the e-paper display. Alternatively, the appliance can be conveniently controlled via the Bluetooth® remote control or with the CLAGE app via smartphone and tablet.
The DEX Next S has an intuitive menu guide where different user profiles can be set up and where collected data can be read out

The inlet temperature can be up to 70 °C so that operation in connection with reheating, e.g. in solar systems, is possible.
It is possible to use the instantaneous water heater in combination with an external load shed-ding relay for electronically controlled instantaneous water heaters (refer to installing instruc-tions).
As soon as you open the hot water tap, the instantaneous water heater switches on auto ma ti cally. When the tap is closed, the appliance automatically switches off. The water heater is operated at the device itself or with an optional wireless remote control.

How to use

Main control
The e-paper display changes automatically to main screen approx. 60 seconds after activation or operation.

Venting after maintenance work
This instantaneous water heater features an automatic air bubble protection to prevent it from inadvertently running dry. Nevertheless, the appliance must be vented before using it for the first time. Each time the appliance is emptied (e.g. after work on the plumbing system, if there is a risk of frost or following repair work), the appliance must be re-vented before it is used again.

  1. Disconnect the instantaneous water heater from the mains (e.g. via deactivating the fuses).
  2. Unscrew the jet regulator on the outlet fitting and open the cold water tap valve to rinse out the water pipe and avoid contaminating the appliance or the jet regulator.
  3. Open and close the hot water tap until no more air emerges from the pipe and all air has been eliminated from the water heater.
  4. Only then should you re-connect the power supply again (e.g. via activating the fuses) to the instantaneous water heater and screw the jet regulator back in.
  5. The appliance activates the heater after approx. 10 seconds of continuous water flow.

Cleaning and maintenance

  • Plastic surfaces and fittings should only be wiped with a damp cloth. Do not use abrasive or chlorine-based cleaning agents or solvents.
  • For a good water supply, the outlet fittings (e.g. jet regulators and shower heads) should be unscrewed and cleaned at regular intervals. Every three years, the electrical and plumbing components should be inspected by an authorised professional in order to ensure proper functioning and operational safety at all times.
