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 set tempera-
ture is adjustable. Upwards of a certain flow rate, the control unit
selects the required heating output, subject to the temperature
selected and the cold water temperature.
The instantaneous water heater with full electronic control and
automatic output matching maintains a consistent outlet tempera-
ture. The fully electronic control unit with motorised valve ensures
the water is accurately heated to the selected temperature. This
occurs regardless of the inlet temperature.
If the appliance is operated with preheated water and the inlet
temperature exceeds the selected temperature, the inlet tempera-
ture is indicated on the second display line and flashes. The water
is not heated further.
You can store different set temperatures and call them up quick-
ly. In the ECO function, the integral motorised valve limits the
flow rate to 3 preset levels. The appliance has functions for a
temperature limit (Tmax function (user) and internal anti-scald-
ing protection (qualified contractor)). 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 after water stops flowing or if no action
is performed.
Heating system
The bare wire heating system is enclosed within a pressure-tested
plastic jacket. The heating system with its stainless steel heater
spiral is suitable for hard and soft water areas and is largely in-
susceptible to scale build-up. The heating system ensures rapid
and efficient DHW provision.
Note
The appliance is equipped with an air detector that large-
ly prevents damage to the heating system. If, during op-
eration, air is drawn into the appliance, the appliance
shuts down heating output for one minute to protect the
heating system.
