3. Appliance description
The appliance switches on automatically as soon as you open the
hot water valve on the tap. When you close the tap, the appliance
switches off again automatically.
The appliance heats water as it flows through it. The DHW outlet
temperature can be variably adjusted. From a certain flow rate,
the control unit regulates the correct heating output, subject to
the temperature selected and the current cold water temperature.
The electronically controlled instantaneous water heater with au-
tomatic output matching maintains a consistent outlet tempera-
ture. It is irrespective of the inlet temperature, up to the maximum
output of the appliance.
If the appliance is operated with preheated water and the inlet
temperature exceeds the selected set temperature, the word "hot"
and the inlet temperature are displayed alternately, and the "hot"
LED flashes. The water is not heated further.
You can save and quickly call up different temperatures. With
the ECO function, the flow rate is limited to 3 preset levels. The
appliance is equipped with functions to permanently limit the
temperature (e.g.for childproofing). The backlight switches on
automatically as soon as water starts to flow through the appli-
ance or you make a change on the user interface. The backlight
switches off automatically 5seconds after water stops flowing or
if no operation has been performed for 30seconds.
You can set the temperature unit and operating lock individually.
Heating system
The bare wire heating system is enclosed within a pressure-tested
plastic jacket. The heating system with its stainless steel internal
indirect coil is suitable for hard and soft water areas and is largely
insusceptible to scale build-up. The heating system ensures rapid
and efficient DHW provision.

4.10 Recommended settings
Your instantaneous water heater offers maximum precision and
maximum convenience in DHW provision. Should you nonetheless
be operating the appliance with a thermostatic valve, we recom-
mend that you:
 Adjust the set temperature on the appliance to over 50°C.
Then set the required set temperature on the thermostatic
valve.
Saving energy
The following recommended settings will result in the lowest en-
ergy consumption:
- 38°C for hand washbasins, showers, bath
- 55°C for kitchen sinks
Internal anti-scalding protection (qualified contractors)
If required, the qualified contractor can set a permanent temper-
ature limit, forexample in nurseries, hospitals etc.
When supplying a shower, the temperature setting range must be
adjusted by the qualified contractor to 55°C or less.
Limiting it in this way prevents water from flowing out of the
appliance at temperatures which could cause injury.
Recommended setting for operation with a thermostatic valve
and water preheated by solar energy
 Set the temperature at the appliance to the maximum
temperature.
Following an interruption to the water supply
!
Material losses
To ensure that the bare wire heating system is not dam-
aged following an interruption to the water supply, the
appliance must be restarted taking the following steps.
 Disconnect the appliance from the power supply by
removing the fuses/tripping the MCBs.
 Open the tap for one minute until the appliance and
its upstream cold water inlet line are free of air.
 Switch the power back ON.
5. Cleaning, care and maintenance
 Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
 Check the taps regularly. Limescale deposits at the tap out-
lets can be removed using commercially available descaling
agents.
