Desert Aire - SP Manual
Figure 14 – Sensor Junction Box Location
The junction box is mounted at the supply air end of the unit, see Figure 14. When using an outdoor
installed SP unit it is recommended that the radiation shield and sensor assembly be mounted to
the SP unit near the provided junction box. The outdoor air temperature / humidity sensor should be
installed in the radiation shield. This assembly then should be installed outdoors near the
dehumidifier when the SP unit is installed indoors.
The shield is included to prevent additional heat loading from the sun and to prevent direct moisture
contact with the sensor. With the curved shape and color of the plates, air flow is able to move across
the sensor to keep radiated temperatures from surrounding surfaces from affecting humidity readings.
