Positioning the outdoor sensor. Figure 57:
• Position the outdoor sensor on the north or north west side of
the house.
• To measure the outdoor temperature as accurately as possible,
the sensor must be positioned 2/3 of the way up the facade on
houses up to three storeys high. For higher buildings, the sensor
should be positioned between the second and third storeys. Its
location must not be completely protected from the wind but
not in a direct draft. The outdoor sensor should not be placed on
reflective panel walls.
• The sensor must be positioned at least 1 m from openings in the
walls that emit hot air.
• If the sensor cable is connected through a pipe, the pipe must be
sealed so that the sensor is not affected by outgoing air.
The outdoor sensor is connected by a two core cable. For a cross
section of 0.75 mm
2
a maximum cable length of 50 m applies. For
greater lengths a cross section of 1.5 mm
2
is used, up to a maxi-
mum of 120 m.
Then connect the sensor to the heat pump control system in
accordance with the instructions below.
