5. Setup Instructions
5.1 Power Connection
The RSTW Pro offers two power input options:
- Using a 4S LiPo Battery Pack:
Connect a 4S LiPo battery pack directly to the built-in XT60 connector on the right side of the tire warmer. No additional adaptors are necessary.
Figure 4: XT60 Connector for 4S LiPo Battery - Using a DC Power Supply (12-18V):
Connect an external DC power supply (12-18V) to the DC input jack on the left side of the tire warmer using the provided DC input cable. For optimum warm-up effect, the DC power supply should continuously provide 12V voltage with a current of 8A.

5.2 Attaching Warming Cups/Belts
Connect the warming cups or belts to the corresponding front and rear output ports on the main unit. Ensure a secure connection for efficient heating.
Place the warming cups/belts onto the tires of your RC car. The silicone material ensures an even fit and efficient heat transfer.
6. Operating Instructions
6.1 Powering On and Initial Display
Once powered, the LCD display will show the current temperature readings for each tire warmer. The four LED indicators will light up, showing the status of each warmer.
- LED Indicator Status:
- Red: The tire warmer is actively heating.
- Green: The tire warmer has reached the preset temperature.
6.2 Setting Temperature
Use the joystick to navigate the intuitive user interface and set the desired temperature. You can set the temperature independently for the front and rear warmers.
- Press the joystick to enter the menu or confirm a selection.
- Move the joystick Up/Down to adjust values.
- Move the joystick Left/Right to navigate between settings (e.g., front temperature, rear temperature, Celsius/Fahrenheit, safety timer).
- The temperature range is 20-80℃ (68-176°F), with a maximum of 100℃ (212°F).
6.3 Other Features
- Temperature Controlled by MCU: Ensures precise and stable temperature management.
- 8 Different Beep Tones: Provides audible feedback for various operations and alerts.
- Celsius / Fahrenheit Switchable: Choose your preferred temperature unit.
- Safety Timer: Set a timer for automatic shutdown to prevent overheating and conserve power.
7. Maintenance
- Cleaning: Ensure the device is powered off and disconnected from all power sources before cleaning. Use a soft, dry cloth to wipe the main unit. The silicone warming cups/belts can be gently wiped with a damp cloth if necessary. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the tire warmer in a cool, dry place away from direct sunlight and extreme temperatures. Disconnect all cables and store the warming cups/belts neatly to prevent damage.
- Inspection: Periodically inspect all cables and connectors for any signs of wear or damage. Replace any damaged components immediately.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | No power supply or incorrect connection. | Check if the 4S LiPo battery is charged and connected correctly, or if the DC power supply is providing 12-18V and connected securely. Ensure the DC power supply provides sufficient current (8A at 12V). |
| Warming cups/belts are not heating. | Loose connection or faulty warmer. | Ensure warming cups/belts are securely plugged into the output ports. Check the LED indicators; if they are not red, the warmer might not be active or could be faulty. |
| Temperature reading is inaccurate. | Environmental factors or sensor issue. | Note that atmospheric conditions can affect tire temperature. If readings are consistently off, contact support. |
| Cannot change settings with joystick. | Joystick malfunction or incorrect operation. | Ensure you are pressing and moving the joystick correctly. If the issue persists, the joystick might be faulty. |
9. User Tips
- Always ensure the warming cups/belts are properly seated on the tires for optimal and even heat distribution.
- Experiment with different temperature settings to find the ideal preheating temperature for your specific tire compound and track conditions.
- Utilize the safety timer feature to prevent over-heating and to manage power consumption effectively during longer race days.
- Keep the LCD screen clean for clear visibility of temperature readings and settings.
