Position the Humidity Sensor
Follow these steps to install the humidity sensor that is connected to the controller box:
1. Open the controller box assembly and locate the humidity sensor (SH) assembly.
2. Remove the cover of the humidity sensor, and then unfasten the harness from the sensor.
3. Thread the harness through the hole at the bottom or top of the controller box and reattach the sensor and then
the cover. Note: If further shipping is required after mounting the controller, secure the humidity sensor under
the controller box with tape to protect the sensor from vibration).
Position Indoor Temperature Sensors and Supply Air Temperature Sensors
An indoor temperature sensor is located at the bottom of the controller box and a backup temperature sensor at the
top of the controller box. The sensor monitors the shelter temperature to control the WPU operation. Slide the sensor
through the port on the bottom left side of the controller box. Tighten the port cover to hold the sensor cable in
place. Follow the same steps to position the backup sensor at the top of the box.
