ANTI LEGIONNAIRES
’ DISEASE PROGRAM
The anti-
Legionnaires’ disease (pasteurisation) program of the boiler can only be used when the boiler is set as an
“indirect” boiler configuration or a “direct” hot water boiler configuration. Only these configurations can activate the
day and time program of the anti-Legionna
ires’ disease function. See the following graphs. The standard factory
setting for this function is “OFF”.

ARAMETERS FOR SETTING THE OUTDOOR GRAPH
When using this function, the flow temperature is calculated based on the measured outdoor temperature. The rela-
tion between the outdoor temperature and the flow temperature can be programmed with the following parameters.
This setting creates the so called “heating curve” (outdoor graph).
The boiler will recognize an outdoor sensor when it is connected. When the sensor is detected the boiler controller
will control the flow temperature based on the heating curve that is programmed.
P5 AA
OutsidPres. (1=On 0=Off)
Outside sensor present.
Setting this parameter to “On” a fault message will be displayed in case of an interrupted connection to the outdoor
sensor or if the measured outdoor temperature exceeds 60°C (defective sensor).
0 =>
No fault message at interrupted outdoor sensor connection. Boiler keeps burning using the value of the
external or internal flow sensor instead of the outdoor sensor.
1 =>
Interrupted sensor wiring causes a fault message to occur at the display Boiler keeps burning using the value
of the external or internal flow sensor instead of the outdoor sensor.
