9.3 Installing the VRC 693 outdoor
sensor
This equipment may only be opened by a
qualified specialist and installed as
shown in the diagram. Current safety
regulations must be followed as well as
the installation instructions for the heat-
ing equipment and for the heating con-
troller.
Installation location
The outdoor sensor should be installed
on the side of the house where the most
frequented rooms are located. If this side
can‘t be clearly identified, then install it
on the north or north-west side of the
house.
To ideally measure the outdoor tempera-
ture, for houses up to three storeys, the
device should be fitted about two thirds
of the way up the wall. For taller build-
ings, installation is recommended
between the 2nd and 3rd floors.
