Operating instructions

2.1

Getting to know your appliance

This appliance is an electronically-regulated, pressurized continuous-
flow heater for decentrally supplying hot water.
The electronic continuous-flow heater heats the water as it flows through
the appliance. One or more taps can be supplied with warm water.
2.1.1

Operating elements and displays

1 Display
2 Rotary selector switch
2.2

Operating the appliance

2.2.1

Switching the appliance on and off

The continuous-flow heater switches on and heats the water when the
warm water tap is opened. It switches off again if the water tap is closed.

2.2.2

Setting the water temperature

• Turn the rotary selector switch.
Any desired temperature can be set between 30 °C to 60 °C in
increments of 0.5 °C.
The display shows the selected temperature.
Note: The displayed temperature is the water temperature inside the
appliance. The temperature of the water leaving the tap can vary from
this due to heat losses in the pipework.
2.2.3

Error message in the display

If an error message "E.." appears in the display or an LED flashes, see
chapter "A fault, what to do?".
2.2.4

Solar heated

The appliance can be operated with pre-warmed water (for example,
from a solar energy unit).
CAUTION:
Attention!
Scalding danger!
▶ If the output temperature of the water leaving the tap is higher than
the set temperature, then this is because the supply water
temperature from the domestic system is too hot, e. g. due to its
being heated by a solar energy unit.
• The thermostatic premixer in the domestic supply must be set
accordingly to lower temperatures.
2.2.5

Startup after power failure

• Open the warm water tap fully and allow water to flow until it is warm.
2.2.6 Using the appliance after switching off the water supply
• Switch off the appliance (unscrew the fuse in the fusebox).
• Open the warm water tap and keep it open until the air has been
completely forced out of the water pipe.
• Switch the fuse back on again.
• Open the warm water tap fully and allow water to flow for at least one
minute.
Only then (for safety reasons) will the appliance begin to heat.
The appliance is now ready to operate.
2.2.7

Saving energy

• Set the desired water temperature directly on the appliance.
Note: Mixing in of cold water at the faucet/fitting consumes unnecessary
water and energy.
This also accelerates calcification (scaling) of the appliance. Therefore,
please always set the desired temperature directly on the continuous-
flow heater.
2.2.8

Winter operation

Note: It is possible in winter that the supply temperature of the water is
reduced and the required outlet temperature is no longer achieved.
• Reduce the water flow on the taps until the desired water
temperature is reached.
