Y FUNC
TIONS
6.4.7 Anti-Legionella
This function is used to heat up the system during selected periods to eliminate legionella bacteria.
Settings range: S1-S8, VFS1-2, Active storage/ Default setting: none
6.4.7.1 AL T Set
This temperature has to be detected for the time set in AL residence time at the AL sensors for a successful heat up.
Settings range: 60°C to 99°C (140°F to 210°F) / Default setting: 70°C (158°F)
6.4.7.2 AL Residence Time
This determines the time span for which the AL T set temperature must be detected for a successful AL heat up.
Settings range: 1-120 min / Default setting: 60 min
6.4.7.3 Last AL Heat
This displays the date and time of the last successful heat up.
No settings
6.4.7.4 AL Sensor 1
This temperature is used to measure the AL temperature.
Settings range: S1-S8, VFS1-2, Active storage/ Default setting: none
6.4.7.5 AL Sensor 2
When a second sensor is connected, both sensors must reach and hold the setpoint temperature for the residence time for a successful heat up.
Settings range: S1-S8, VFS1-2, Active storage/ Default setting: none
6.4.7.6 AL-Times
During this periods the AL heat up is attempted.
Setting range: from 00:00 to 23:59 / default setting: 06:00 to 22:00
CAUTION
This anti-Legionella function does not provide complete protection against Legionella, because the controller is dependent on
sufficient energy being fed in, and it is not possible to monitor the temperatures in the entire range of the storage tanks and
the connected piping system. To provide complete protection against Legionella bacteria, it must be ensured that the tem-
perature is raised to the necessary temperature, and at the same time there must be water circulation in the storage tank and
piping system by means of other additional energy sources and external control units.
CAUTION
The anti-Legionella function is switched off at delivery. Whenever heating-up has been carried out with the anti-Legionella
function switched on, an information message with the date appears on the display.
