![TST TPMS]()
This TST tire pressure monitoring system monitors the pressure and temperature level of the tires on your RV, motorhome, 5th wheel, motor coach, or trailer. The system utilizes flow through sensors that attach to the valve stems of your tires. The flow through design lets you inflate or deflate your tires without removing the sensors. When a tire sensor detects an anomaly, it will wirelessly transmit an alert to the included digital color monitor. Your monitor will emit flashing lights and an audible alert to notify you of an issue, and it will display details regarding the anomaly. A booster is included to strengthen and amplify the signal that the sensors are sending to the display monitor.
Initial Setup
The TST TPMS is easy to set up and includes all mounting hardware and tools for installation. First, assign the tire sensor positions through the monitor's Learning Mode. Label each sensor with the corresponding numbering code sticker so that you know which sensor is programmed to which tire position. When you are setting up the sensors make sure the one you are programming is at least 2' away from the other sensors. Otherwise the other sensors will interfere with the sensor you are attempting to program. Once the tire sensors have been recognized by the monitor, attach them to the valve stems of your vehicle's tires. Next, install the booster and connect it to a 12-volt power source on your vehicle or trailer.

Use the included suction cup holder to mount the color monitor on your windshield so you can monitor your tires while you drive. You can also use the included rubber, non-slip cradle mount to set the monitor on your dashboard.
TST Color Monitor Display
![App Diagram]()
- Current Tire Selection - The tire icons indicate the position of your tires. A solid tire icon indicates that tire is programmed into your current setup. A blinking tire icon indicates that tire is experiencing an anomaly.
- Sensor Low Battery Alert - This displays when one of the sensor's batteries is low. The corresponding tire light will also flash to indicate which sensor's battery is affected.
- Display Battery Level Indicator - Shows the charged level of the internal battery. When this icon shows one bar it is recommended to charge the display as soon as possible. It takes approximately 4 hours for the battery to fully charge.
- Out Of Parameter Alert - This icon will flash during a high or low pressure alert, a high temperature alert, or a fast leak alert. In conjunction with this flashing light, the affected tire light will flash, the HI or LO PRESSURE, HI TEMP, or FAST LEAK indicators will light up, and an audible alert will sound.
- Display Alerts - These icons, along with the specific tire icon, will light up to indicate HI or LO PRESSURE, HI TEMP, or FAST LEAK. The bottom row indicates which programming mode you are in.
- Red LED Indicator - Lights up during an alert.
- Antenna - The multidirectional antenna helps eliminate electronic interference when paired with the signal booster.
- Temperature Indicator - Displays the current temperature of the selected tire in Fahrenheit or Celsius. This will also display your selected high temperature parameter during programming.
- Tire Pressure Indicator - Displays the current tire pressure of the selected tire. This will also display your selected high and low pressure parameters during programming.
- Power Switch - Lets you turn the monitor on and off.
- Charging Port - Plug the included USB cable into this port to charge the monitor. The side power switch will not turn off the display when constant power is applied to the unit.
- Backlight and Motion Detector - The backlight turns on when the vehicle is in motion, and there is little ambient light. It will sense periods of inaction and the display will "go to sleep" until the vehicle resumes motion.
TST Color Monitor Function Buttons
![App Diagram]()
- GO Button - Press the GO button to tell the system where to "go". When pairing the sensors, once you have the tire icon flashing that you want to code, hit the GO button to tell it to get its unique code. If you only want to code a trailer, press the GO button to tell it to go to the trailer. When moving from axle to axle to set your warning pressures, hit the GO button to go to the next axle or next trailer.
- SET Button - Press the SET button to program your warning parameters, or to go into coding and set your configurations. This button locks in all specific settings.
- BACK Button - Press the BACK button to leave programming, or take the system back to the previous screen. If you need to remove a sensor code, use this button in the coding section to take the sensor position back to the factory settings.
- + Button - Press the + button to increase the temperature and pressure settings from the factory defaults. You can also scroll forward through your tires. Press the + button in conjunction with the GO button to drop your towing vehicle from a setting and add it back in.
- - Button - Press the - button to decrease the temperature and pressure settings from the factory defaults. You can also scroll backward through your tires. Press the - button in conjunction with the GO button to drop your towed vehicle from a setting and add it back in.
Multiple Wheel Layouts
![TST TPMS]()
You can program multiple layouts into the monitor, and you can scroll through each setup on the screen. This system can support up to 4 tire layouts and up to 38 tires total. Make sure to set your high and low pressure alarms for each layout that you are using. Some examples of popular layouts are shown above.
Tire Sensor Installation
![Tire sensor Install Diagram]()
- Screw the anti-theft hex nut onto your tire's valve stem threads until it bottoms out.
- Screw the sensor onto the valve stem. Tighten the sensor until the air stops leaking and the sensor bottoms out on the valve stem. Give it a slight twist to seat the sensor while being careful not to over-tighten.
- Use the included wrench to tighten the hex nut counterclockwise until it is snug against the sensor.
- Screw the tire's valve cap onto the sensor.
Note: To inflate or deflate a tire it is not necessary remove the sensor. Simply unscrew the cap.
Booster
![repeater]()
The booster - or repeater - amplifies the signal strength that the sensors send to the monitor. Booster installation requires a 12-volt power source. It is waterproof and can be mounted inside or outside your vehicle with the included mounting hardware. On a trailer, you can mount it in the battery box in front of the propane bottles. On a 5th wheel, you can install it in the house battery bay underneath the overhang. You will want to place it below the bank of mirrors so they don't bounce the signal back and cause the system to malfunction. On coaches with towed vehicles, you can install it in the back battery bay. The power draw is so minimal that you can leave the booster installed without running the battery down. If you decide to unhook it for storage remember to reconnect when you are ready to hit the road. A red light on the repeater indicates that the unit is connected to power and operating correctly. Repeater installation is required for warranty compliance.
