4. Setup and Installation
Follow these general steps for setting up your Briidea HX-076 controller. Always ensure power is disconnected before handling electrical components.
- Choose Location: Select a suitable location in your crawl space, basement, attic, or garage where the controller can be easily accessed and the sensor probe can accurately measure the environment.
- Mount the Controller: Securely mount the controller unit to a wall or sturdy surface using appropriate fasteners. The heavy metal shell is designed for durability in various environments.
- Position the Sensor Probe: Place the humidity/temperature sensor probe in a central location within the area to be monitored, away from direct airflow from fans or heat sources, to ensure accurate readings.
- Connect Devices: Plug your ventilation fans, dehumidifiers, or other controlled devices into the two plug-in outlets on the controller. Ensure the individual on/off switches for each outlet are in the desired position.
- Power On: Plug the controller's power cord into a standard 120VAC outlet.

5. Operating Instructions
The Briidea HX-076 offers straightforward operation with its control knob and mode switches.
- Select Control Mode: Use the two individual on/off switches to select your desired control mode:
- Dehumidistat Mode: Activates connected devices based solely on humidity levels.
- Thermostat + Dehumidistat Mode: Activates connected devices based on both temperature and humidity levels.
- Set Humidity Level: Rotate the central knob to set your desired humidity level (ranging from 10% to 80%). The controller will automatically activate connected devices when the ambient humidity rises above this set point and deactivate them when it falls below.
- Freeze Protection: The unit is equipped with a freeze protection thermostat. If the outdoor temperature drops below 32°F (0°C), the fan will stop working to protect the unit and prolong its service life.

6. Maintenance
To ensure optimal performance and longevity of your Briidea HX-076 controller, regular maintenance is recommended:
- Cleaning: Periodically wipe the controller unit and sensor probe with a soft, dry cloth to remove dust and debris. Do not use abrasive cleaners or immerse the unit in water.
- Connection Check: Regularly inspect all electrical connections, including the power cord and device plugs, to ensure they are secure and free from damage.
- Environmental Check: Ensure the sensor probe remains unobstructed and is not exposed to extreme conditions that could affect its accuracy.
7. Troubleshooting
If you encounter issues with your Briidea HX-076 controller, consider the following troubleshooting steps:
- No Power: Check if the power cord is securely plugged into a live outlet. Verify the outlet is functioning by plugging in another device.
- Devices Not Activating:
- Ensure the individual on/off switches for the outlets are in the 'on' position.
- Verify that the set humidity/temperature levels are appropriate for activation.
- Check if the connected devices are powered on and functioning correctly when plugged directly into a wall outlet.
- Inaccurate Readings: Ensure the sensor probe is clean, undamaged, and positioned correctly away from direct drafts or heat sources.
- Freeze Protection Active: If the unit is not operating and the temperature is near or below freezing, the freeze protection feature may be active. Operation will resume when temperatures rise.
If problems persist after attempting these steps, please contact customer support.
