4.15.2. outside Temperature Sensor
location of device
•
The most important rule for locating the Outdoor Temperature Sensor is that it should have the same temperature, wind, and
solar conditions as the occupied rooms. In most cases, the Outdoor Temperature Sensor is to be mounted on the coldest side
of the building (N–NW side) so as not to be affected by direct sunshine. This is to ensure that it will be warm enough in each
room of the house. Only when the windows of all the rooms to be regulated face in the same direction can the sensor element
be mounted onto the outside of this same wall. This can also be the south side of the house. The Outdoor Temperature
Sensor’s protective housing prevents the sun’s rays from affecting the sensor. If the sensor has been mounted on the south
side of a house with large windows facing in this direction, it is recommended that you remove the sun guard. Do not mount
the Outdoor Temperature Sensor in a protected area, such as a wall niche or under the balcony. It should be put on an open
façade so that it can detect all weather conditions. Avoid mounting the sensor above doors and windows since warm air
movements may otherwise influence the measurement results. The Temperature Sensor should be mounted about 2/3 the
way up the wall on buildings of not more than 3 stories; on taller buildings, between the second and third stories.
