Protecting from Legionella
The controller is furnished with an anti-Legionella func-
tion to protect from infection by germs (Legionella).
Set the anti-Legionella function when installing the
controller.
Preventing the risk of scalding
There is a danger of scalding at the hot water draw-off
points when the target temperatures are in excess of
60 °C. Young children and elderly persons are particu-
larly at risk, even at lower temperatures.
Select a moderate target temperature.
When the anti-Legionella function is active, the DHW
cylinder is heated to over 65 °C for at least one hour.
Inform the owner about the risk of scalding when the
anti-Legionella function is active.
Protecting the controller from damage
Make sure that the controller is protected from mois-
ture and water splashes.
Avoiding malfunctions
To avoid malfunctions, take care that
the heating installation is only operated in a tech-
nically perfect condition,
no safety or monitoring devices have been remo-
ved, bridged out or disabled,
faults and damage that affect safety are rectified
immediately.
Make the owner aware that
the controller must not be obstructed by furniture,
curtains or other objects if it is installed in the
living room,
all the radiator valves in the room where the con-
troller is installed must be turned fully open.
Preventing frost damage
If there is a power cut or if the room temperature is set
too low in individual rooms it can not be ruled out that
sections of the heating system are damaged by frost.
Inform the owner as to how to ensure protection
from frost.
