Positioning of the outdoor sensor

2/3 x H

Recommended location

Unsuitable location

Position the outdoor sensor on the north or north west side of the

house.

Make sure that the outdoor sensor is not placed in direct sun light.

For higher buildings, the sensor should be positioned between the

second and third storeys. Its location must not be completely pro-

tected 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.
