Anti-legionella
function The anti-Legionella function can only be activated globally for all
cylinder charging circuits.
When the anti-Legionella function is enabled, the respective cylin-
der and the corresponding hot water pipes are heated up to a
temperature of 70 °C at the set time. To this end the respective
target cylinder temperature is automatically raised to 70 °C (with
5 K hysteresis). The corresponding circulation pump is switched
on.
The function is terminated automatically when the cylinder sensor
measures a temperature
≥
60 °C for longer than 60 mins, or after
a period of 90 mins has elapsed (to avoid getting “stuck“ in this
function if water is drawn simultaneously).
Default setting = Off means:
no anti-Legionella function (due to danger of scalding).
