Temperature setting
You can set the required temperature gradually to a lower or higher value with the keys
and
.
The temperature changes by 1 °C, in the convenience zone between 35 °C and 42 °C by
0.5 °C, if key is pressed shortly one time. Pressing a key for a longer time changes the
temperature continuously.
Note: If temperature is set below 20 °C with key
appliance switches off the heating function.
Note: If the water heater supplies a shower, the maximum temperature was reduced
during initial operation. This limitation cannot be exceeded.
Programme buttons
The two programme buttons allow to quickly select the preset temperature. When
pressing a programme key, the preset temperature is selected and displayed. The
factory setting for programme
assign your own settings for the programme keys:
• Prolonged pressing of the programme key stores the previously selected tem-
perature. The display changes from "P1" or "P2" to the newly stored temperature
value. This newly set temperature is now available to you each time you press the
corresponding program key.
Key lock
The sensor keys can be locked to prevent unwanted entries. Press
for approx. 5 seconds to activate / deactivate the key lock.
When a key is pressed with the key lock active, a key symbol appears on the display.
ECO mode
The symbol
shows that the appliance works in an energy saving mode i.e. the
momentary energy consumption is subject to the selected temperature and to the
flow rate in the energy saving mode.
Power limit
If the full output of the instantaneous water heater is not sufficient to heat the tapped
water quantity, this is indicated by the decimal point lighting up (e.g. in winter when
several taps are open at the same time). By reducing the hot water flow, the dot stops
lighting up as the power is again sufficient to reach the set temperature.
How to save energy
Set the exact temperature you need on the appliance and open the hot water tap.
Once you feel that the water is too hot, do not add any cold water and, instead, enter
a lower temperature on the appliance. If you were to add cold water, the water already
heated would cool down again and valuable energy would be wasted. Moreover, the
cold water added in the tap is not covered by the control range of the electronic cir-
cuitry, with the result that temperature constancy is no longer guaranteed.
