Temperature limitation
This instantaneous water heater is equipped with an optional temperature limiting
function. This scalding protection is deactivated in the works setting.
Switch on:
Select the limit tem per ature with arrow keys and , then press info key and
arrow key simultaneously for at least 3 sec. The display briefly confirms the activa-
tion by “
TEMP PROTECTION ENABLED
”.
After activation of the scalding pro tec tion it is impossible to select a higher tempera-
ture.
Switch off:
Press info key and arrow key simultaneously for at least 3 sec. The display briefly
con firms the deacti vation by “
TEMP PROTECTION OFF
”.
Reset to factory setting
All factory settings can be recalled:
• Press setup key , the display now counts backwards from “10” to “00” in second

Power limit
If the full output of the instantaneous water heater DSX does not suffice to heat the
tapped quantity of water, the control valve automatically reduces the flow rate so that
the set temperature is reached.
Top-up heating
When operating with preheated water (e.g. with solar systems), you must ensure that
the inlet temperature does not exceed 70 °C.
If the inlet temperature exceeds the setpoint, the appliance is not providing any out-
put, and the display shows “
INLET TEMP TOO HIGH
”.
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.
