Recommended location
Unsuitable location
Figure 40: Connecting the outdoor sensor.
Position the outdoor sensor on the north or north west side of
l
the house.
To measure the outdoor temperature as accurately as possible,
l
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
l
walls that emit hot air.
If the sensor cable is connected through a pipe, the pipe must be
l
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 mm2 a maximum cable length of 50 m applies.
For greater lengths a cross section of 1.5 mm2 is used, up to a
maximum of 120 m.
Then connect the sensor to the heat pump control system in
accordance with the instructions below.
Figure 41: Connecting the outdoor sensor.
1.
Route the outdoor sensor connection cable through the cable
bushing in the top panel to the terminal block.
2. Connect the sensor to the terminal blocks according to the
