This setting can be set within the range of 1÷10, where "1" denotes minimum speed, and "10" maximum
speed.
You can modify this setting in a similar way to the described in sections 6 and 6.2.

"02", "03", "04" (⇒ section 8.2 page 8). You can modify this setting in a similar way to the described in
sections 6 and 6.2. Settings are within the range of 35°C to 65°C.

To activate the ANTI-LEGIONELLA function, set the U6 setting to 1.

You can turn off the function by modifying the U6 setting to 0, or by pressing
function is also cancelled after a power down.
