Saving energy
Mixing in of cold water in the fitting requires unnecessary water and
energy. You should therefore set the desired water temperature di-
rectly on the continuous-flow heater and then open the water tap.
If “eco” lights up in the display it means that the appliance is being
run economically.
Performance indicator
The performance indicator shows the currently used performance
of the continuous-flow heater in 10 % increments.
An example: 7 increments are shown while drawing off hot water.
This means that the continuous-flow heater is currently only running
at 70 % of its maximum output.
If all 10 segments blink, then the power limit has been reached. Re-
duce the water flow rate until the segments do not blink any longer.
Pre-warmed water
The continuous-flow heater can be operated with pre-warmed wa-
ter (for example from a solar energy unit). The “Symbol Sun” will ap-
pear in the display if the feed water temperature is above 30 °C.
Service
Please seek to remove a fault according to guidelines given in the
chapter “A fault, what to do?” if “service” lights up in the display.
