6. Secure the sensor to the bottom of the box with a nylon zip-tie.
7. Secure the box to the outside wall. Snap the sensor box cover in place and use sealant along the
seam between the box and the wall.
Note: punching out the holes on the sides and the bottom of the sensor box is critical to allow proper
airflow and drainage from rain and dew.
Figure 14: Ensure No Leakage
Important. Ensure no air leakage exists from inside the shelter to the box housing the outdoor
temperature sensor. Any path whereby air could exit the shelter and arrive in the sensor box will
adversely affect the outdoor temperature sensor reading.
