Note
If the outlet temperature is not high enough when the
draw-off valve is fully open and the temperature selector
is set to maximum, then more water is flowing through
the appliance than can be heated by the heating system
(appliance working at maximum output).
 Use the ECO button to reduce the water volume until
the required temperature is achieved.
4.4 Temperature limit via internal anti-scalding
protection (qualified contractor)
If required, the qualified contractor can set a permanent temper-
ature limit, for example in nurseries, hospitals,etc.
When supplying a shower, the appliance temperature setting
range must be adjusted by the qualified contractor to 55°C or less.
If the anti-scalding protection function is enabled, "Tmax" flashes
continually once the set temperature has been reached.
4.5 Temperature limit Tmax (user)
The temperature limit allows you as a user to restrict the adjusta-
ble set temperature at the appliance to a maximum value.
Your qualified contractor can set an additional temperature limit
for anti-scalding protection. This temperature then dictates the
upper limit of the setting range for the temperature limit function.
