13.1 OUTDOOR TEMPERATURE SENSOR INSTALLATION
To install the outdoor temperature sensor, perform the following procedure.
Installing the Outdoor Temperature Sensor
1. Remove the front cover and mounting screws / anchors from the sensor enclosure.
Figure 13-1: Outdoor Sensor Enclosure and Components
2. When mounting the enclosure, the exterior wall selected should represent the heat load of
the building. Typically a northern or northeastern wall will suit most buildings. A southern
facing wall for those buildings, which may have large glass walls or windows on the southern
face.
3. Ensure the sensor enclosure is shielded from direct sunlight or the effects of heat or cold
from other sources (exhaust fans, appliance vents...) to prevent false temperature sensing.
4. Mount the sensor enclosure at an elevation on the exterior wall to prevent accidental damage
or tampering.
5. Avoid mounting the enclosure in areas subjected to excessive moisture.
6. Once an area on the exterior wall has been determined, follow the manufacturer’s mounting
instructions included with the outdoor sensor.
