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 50°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.
How to save energy
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 temperature 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 protection 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
confirms the deactivation 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
intervals. The appliance is reset at value “00” – if you stop pressing the key earlier,
the process will be cancelled.

7. Maintenance work
N.B. Maintenance work must only be carried out by a qualified tradesperson
familiar with instantaneous water heaters.
• Plastic surfaces and fittings should only be wiped with a damp cloth. Do not use
abrasive or chlorine-based cleaning agents or solvents.
• For a good water supply, the outlet fittings (special tap aerators and shower heads)
should be unscrewed and cleaned at regular intervals. Every three years, the electri-
cal and plumbing components should be inspected by an authorised professional in
order to ensure proper functioning and operational safety at all times.
This instantaneous water heater features an automatic air bubble protection to pre-
vent it from inadvertently running dry. Nevertheless, the appliance must be vented
before using it for the first time. Each time the appliance is emptied (e.g. after work on
the plumbing system, if there is a risk of frost or following repair work), the appliance
must be re-vented before it is used again.
1. Disconnect the instantaneous water heater from the mains (e.g. via deactivating the
fuses).
2. Unscrew the jet regulator on the outlet fitting and open the cold water tap valve to
rinse out the water pipe and avoid contaminating the appliance or the jet regulator.
3. Open and close the hot water tap until no more air emerges from the pipe and all
air has been eliminated from the water heater.
4. Only then should you re-connect the power supply again (e.g. via activating the
fuses) to the instantaneous water heater and screw the jet regulator back in.
5. The appliance activates the heater after approx. 10seconds of continuous water
flow.
