WARNING
:
During the time the Legionella function is
performed, there is a risk of scalding when opening the taps.
Legionella function
When the Legionella function is activated, the DHW storage tank temperature is periodically raised
to the Legionella funct setpoint. The Legionella funct setpoint can be maintained during the set
dwelling time.
Off
Function is deactivated.
Periodically
The Legionella function is repeated according to the period (Legionella funct
periodically 1641)). If the Legionella setpoint is attained via solar heating – independent
of the selected interval – the time period is started again.
This means that the heat source is switched on only if the solar plant was not able to
ensure the required Legionella funct setpoint within the set period of time.
Fixed weekday
(The Legionella function can be activated on a fixed Legionella funct weekday (1642)).
When using this setting, heating up to the Legionella setpoint takes place on the
selected weekday, independent of previous storage tank temperatures.
This setting is intended primarily for plant without solar integration.
Legionella function setpoint
The Legionella setpoint can be adjusted between 55 °C and 95 °C. When the Legionella function is
activated, the DHW storage tank is heated up until the value set here is reached. For the Legionella
function to be regarded as fulfilled, sensor B3 at the top or both sensors B3 and B31 must reach the
Legionella setpoint which must be maintained for the set dwelling time, depending on Type of
charging (5022).The higher the temperature level of the storage tank, the shorter the required
dwelling time at that level.The figures given in the table are guide values. They do not guarantee
that legionella viruses will be completely killed.
