6. Setup & Installation

The NENEN HSH-DV3A sensor is designed for easy installation. Follow these steps for proper setup:

1. Sarudza Nzvimbo: Choose a suitable location within the air duct where temperature and humidity measurements are representative of the overall airflow. Avoid areas with stagnant air or direct exposure to heat sources/coolants.
2. Gadzirira Hole Yekukwira: Drill an appropriately sized hole in the air duct for the sensor's probe. Ensure the hole is clean and free of debris.
3. Mount Sensor: Insert the sensor probe into the prepared hole. Secure the main housing to the exterior of the duct using appropriate fasteners (not included, typically self-tapping screws or bolts) through the mounting plate. Ensure a tight seal to prevent air leakage.
4. Wiring: Connect the sensor to your control system or data logger. Refer to the wiring diagram provided with your specific control system for correct terminal connections. The sensor requires a 24V power supply. Ensure all connections are secure and insulated.
5. Power On: Once installation and wiring are complete, apply power to the sensor. The device will begin monitoring automatically.

Cherechedza: For optimal performance, ensure the sensor probe is fully immersed in the airflow.
