4. Setup

The ThermoPro TP210B units are pre-paired at the factory. Follow these steps for initial setup:

1. Install Receiver Batteries: Open the battery compartment on the back of the receiver unit. Insert 2 AAA batteries, ensuring correct polarity (+/-). Close the compartment.
2. Charge Transmitters: Connect the provided USB charging cable to the charging port on each transmitter unit and to a standard USB power source (e.g., phone charger, computer USB port). The LED indicator will show charging status. Charge fully before first use.
3. Power On Transmitters: Press and hold the power button on each transmitter unit until the LED indicator flashes.
4. Verify Connection: The receiver unit should automatically display temperature readings from both transmitters. If not, refer to the Troubleshooting section for re-pairing instructions.

• Channel 1 Temperature: Typically for the refrigerator.
• Channel 2 Temperature: Typically for the freezer.
• Max/Min Records: Highest and lowest temperatures recorded since the last reset.
• Low Battery Indicator: Appears when receiver or transmitter batteries are low.
• Signal Strength Indicator: Shows connection status to transmitters.

5.2 Temperature Unit Selection (°F/°C)

To switch between Fahrenheit (°F) and Celsius (°C), press the LIGHT °F/°C button on the receiver unit.

5.3 Setting Temperature Alerts

The system allows you to set custom high and low temperature limits for each channel. An audible and visual alarm will activate if the temperature exceeds these limits.

1. Press the MODE button once to enter the alarm setting mode for Channel 1 (refrigerator). The high limit will flash.
2. Use the UP or DOWN buttons to adjust the desired high temperature limit.
3. Press MODE again to set the low limit for Channel 1. Adjust with UP or DOWN.
4. Press MODE a third time to enter the alarm setting mode for Channel 2 (freezer). Repeat steps 2 and 3 for Channel 2.
5. Press MODE again to exit alarm setting mode. The alarm icon will appear next to the channel if an alarm is active.

5.4 Viewing and Clearing Max/Min Records

The receiver automatically records the maximum and minimum temperatures for each channel since the last reset.

• Press the HISTORY/CLEAR button once to view the maximum recorded temperatures for both channels.
• Press HISTORY/CLEAR again to view the minimum recorded temperatures for both channels.
• To clear the Max/Min records, press and hold the HISTORY/CLEAR button for 3 seconds while viewing the records. The display will reset to current temperatures.

5.5 Placement Guidelines

Optimal placement ensures accurate readings and reliable wireless communication.

• Receiver Placement: The receiver can be placed on a countertop using its integrated stand, mounted magnetically to a metal surface (e.g., refrigerator exterior), or hung on a wall using the hanging hole. Position it within 500 ft (150 m) of the transmitters, minimizing obstructions.
• Transmitter Placement: Place transmitters inside the refrigerator and freezer compartments. They can stand on a shelf or clip onto a rack. Ensure they are not directly exposed to cold air vents or heating elements, which could affect accuracy.

6. Maintenance

• Cleaning: Wipe the units with a damp cloth. Do not immerse in water or use abrasive cleaners.
• Battery Replacement (Receiver): When the low battery indicator appears for the receiver, replace the 2 AAA batteries.
• Transmitter Charging: When the low battery indicator appears for a transmitter, recharge it using the provided USB cable. A full charge ensures reliable operation, especially in low-temperature environments.
• Storage: If storing the device for an extended period, remove the AAA batteries from the receiver and ensure transmitters are fully charged before storage. Store in a dry, cool place.

7. Troubleshooting

• No Temperature Readings / Lost Connection:
  • Ensure both the receiver and transmitters are powered on.
  • Check battery levels for both units. Recharge or replace as needed.
  • Move the receiver closer to the transmitters. Walls, metal appliances, and electronic devices can interfere with the wireless signal.
  • Re-pairing: If connection is lost, try re-pairing. Power off all units. Power on the receiver. Then, power on each transmitter one by one. They should automatically reconnect.
• Inaccurate Readings:
  • Ensure transmitters are not placed directly in front of cold air vents or near heat sources.
  • Allow units to stabilize for 30 minutes after placement to get accurate readings.
  • Compare readings with another known accurate thermometer if possible.
• Alarm Not Sounding:
  • Verify that the high/low temperature limits are set correctly for each channel.
  • Ensure the alarm function is enabled (check for the alarm icon on the display).
