How do I configure my Hieha RV Tire Pressure Monitoring System (CZ-TYJC-4Tires) to only show 5 sensors and stop the alarm for a removed sensor?

To stop the alarm for the missing sensor on your Hieha RV TPMS, you need to unpair or "delete" that specific sensor position from the monitor's memory. While the provided manual summary focuses on initial setup, most Hieha systems use the following logic for sensor management:Factory Reset: The manual suggests that resetting the system to factory defaults and then re-pairing only the 5 active sensors is a reliable way to resolve configuration issues. This ensures the monitor is no longer looking for the 6th sensor.Manual Unpairing: Typically, you can enter the pairing mode (often by long-pressing a 'Code' or 'Menu' button), navigate to the specific tire position that is alarming, and use a specific button combination (often holding the '-' or 'Set' button) to clear the data for that position.Sensor Data Loss Alarm: Because you removed the battery and the sensor, the monitor is currently triggering a "Sensor Data Loss Alarm." The monitor will continue to alarm as long as it expects a signal from that ID.Recommended Steps:Perform a factory reset as mentioned in the troubleshooting section of your manual.Follow the Initial Pairing instructions to pair only the 5 sensors currently installed on your tires.Leave the 6th tire position empty during the pairing process; the monitor should then only display and monitor the 5 active positions.If you need specific button-press sequences for your exact firmware version, you can contact Hieha 24-hour after-sales service through your original point of purchase for the full technical manual.

Sensor Installation

The external sensors are designed for easy and quick installation on your tire valves. They are lightweight and durable.

Ensure tires are at recommended pressure before installation.
Unscrew the original valve cap.
Screw on the anti-theft nut.
Screw the sensor onto the valve stem. Ensure the sensor is tightened securely to prevent air leakage.
Tighten the anti-theft nut against the sensor using the provided wrench.
Repeat for all six tires.

Initial Pairing and Calibration

The sensors are typically pre-paired with the monitor. If a sensor is replaced or not displaying data, refer to the user manual for specific pairing instructions. Some users have found resetting the system to factory defaults and re-adding sensors can resolve initial setup issues.

Operating Your TPMS

Real-time Monitoring

The 7.84-inch color screen provides clear, real-time display of tire pressure and temperature for all connected tires. The display is designed for readability even in varying light conditions.

Alarm Functions

The system provides timely warnings for critical tire conditions:

Air Leakage Alarm: Alerts for rapid pressure drops.
Low Pressure Alarm: Warns when tire pressure falls below a set threshold.
High Pressure Alarm: Alerts when tire pressure exceeds a set threshold.
High Temperature Alarm: Notifies if tire temperature becomes excessively high.
Sensor Data Loss Alarm: Indicates a sensor is not transmitting data.
Low Battery Alarm: Alerts when a sensor's battery is low.

Smart Features

Intelligent Wake-up & Sleep Monitor: The monitor automatically wakes up upon detecting driving vibration and enters sleep mode when the vehicle stops, conserving battery life.
130FT Sensing Distance: The system's strong antenna signal allows for reliable data transmission up to 130 feet, eliminating the need for a repeater in most large vehicles.

Maintenance

To ensure the longevity and accuracy of your Hieha TPMS, follow these maintenance guidelines:

Monitor Charging: Regularly expose the monitor to sunlight for solar charging or use the USB cable to maintain its 5000mAh battery. The monitor is designed for 24-hour continuous battery life.
Sensor Care: The sensors are waterproof and dust-proof. Periodically check them for any physical damage or signs of wear. Ensure they remain securely tightened on the valve stems.
Cleaning: Clean the monitor screen and sensors with a soft, dry cloth. Avoid abrasive cleaners or solvents.

Troubleshooting

If you encounter issues with your TPMS, refer to the following common problems and solutions:

Problem	Possible Cause / Solution
Sensors not reading or displaying data.	Ensure sensors are correctly installed and tightened. Check for sensor battery low alarm. Try rebooting the monitor. If replacing a sensor, ensure it is properly paired according to the full user manual. Consider resetting the system to factory defaults and re-pairing sensors if initial setup issues persist.
Inaccurate pressure/temperature readings.	Verify tire pressure with a reliable gauge. Ensure sensors are securely attached and not loose. If a sensor displays an unchanging or incorrect reading after a tire event (e.g., blowout), verify sensor placement and consider recalibration or replacement. Avoid changing factory default settings unless instructed. Resetting to factory defaults can often resolve calibration issues.
Monitor not turning on or losing power.	Ensure the monitor is fully charged via USB or sufficient solar exposure. Check the power button.
Weak signal or intermittent connection.	Ensure the monitor's antenna is properly extended. Minimize obstructions between sensors and monitor. The system is designed for 130FT range, but extreme distances or interference can affect performance.
