Recommended settings

Your instantaneous water heater offers maximum precision and
maximum convenience in DHW provision. Should you nonetheless
be operating the appliance with a thermostatic valve, we recom-
mend that you:
f Set the temperature at the appliance to the maximum tem- f
perature. Then set the required set temperature on the ther-
mostatic valve.
Saving energy
The following recommended settings will result in the lowest en-
ergy consumption:
- 38 °C for hand washbasins, showers, bath
- 55 °C (50 °C für DHB-E 13 AU) for kitchen sinks
Internal anti-scalding protection (qualified contractors)
If required, the qualified contractor can set a permanent temper-
ature limit, for example in nurseries, hospitals, etc.
Limiting it in this way prevents water from flowing out of the
appliance at temperatures which could cause injury.
Recommended setting for operation with a thermostatic valve
and water preheated by solar energy
f Set the temperature at the appliance to the maximum f
temperature.
