4.3 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:
Adjust the set temperature on the appliance to over 50°C.
Then set the required set temperature on the thermostatic
valve.
Saving energy
The following recommended settings will result in the lowest en-
ergy consumption:
- 38°C for hand washbasins and bathtubs
- 55°C 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
Set the temperature at the appliance to the maximum
temperature.
