4. Setup Guide
4.1. Installing Batteries (Indoor Monitor)
- Locate the battery compartment on the back of the indoor temperature monitor.
- Open the battery cover.
- Insert 1 AAA battery, ensuring correct polarity (+/-).
- Close the battery cover securely.
4.2. Initial Charging (Floating Thermometer)
The floating thermometer is solar-powered and contains a built-in rechargeable lithium battery. For optimal performance, place the thermometer in direct sunlight for several hours before first use to ensure a full charge. The device can also be charged via a USB cable (not included) if solar charging is insufficient.

4.3. Pairing
The floating thermometer and indoor monitor are typically pre-paired at the factory. Once both units are powered on, they should automatically connect. The indoor monitor will display the outdoor temperature (from the floating unit) and the indoor temperature.
If the units do not connect, ensure both are within range and try restarting them by removing and reinserting batteries (for the receiver) or placing the thermometer in direct sunlight (for the floating unit).
5. Operating Instructions
5.1. Understanding the Display
Both the floating thermometer and the indoor monitor feature clear LCD displays. Refer to the diagram below for an explanation of the display icons and readings.

- Transmitter (Floating Unit): Displays current water temperature, wireless transmission indicator, and battery level indicator.
- Receiver (Indoor Monitor): Displays indoor temperature, outdoor (pool) temperature, low battery indicators for both units, wireless reception indicator, and channel number.
5.2. Switching Temperature Units (°C/°F)
Both the floating thermometer and the indoor monitor allow you to switch between Celsius (°C) and Fahrenheit (°F). Look for a dedicated button labeled "°C/°F" or similar on each unit and press it to toggle the display unit.
5.3. Checking Max/Min Temperatures
The indoor monitor can record and display the maximum and minimum temperatures measured over a period. Press the "MAX/MIN" button on the indoor monitor to cycle through the current, maximum, and minimum temperature readings for both indoor and outdoor temperatures.
6. Placement and Usage
For accurate readings and optimal wireless transmission, consider the following:
- Floating Thermometer: Allow the thermometer to float freely in the water. You may use the included nylon tether to secure it to the side of your pool or hot tub if desired. Ensure the solar panel is exposed to sunlight for continuous charging.
- Indoor Monitor: Place the indoor monitor in a central location within your home, away from direct sunlight or heat sources, to ensure accurate indoor temperature readings. For best wireless reception, minimize obstructions between the floating unit and the indoor monitor.
Image 6.1: The Circrane thermometer is suitable for various applications including swimming pools, hot springs, aquariums, fish ponds, spas, and baby baths.
Image 6.2: The wireless transmission range can reach up to 230 feet in an open field. Obstructions like walls may reduce this distance.
7. Maintenance
- Cleaning: Wipe the thermometer and monitor with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Waterproof Rating: The floating thermometer is IPX8 waterproof, meaning it can withstand continuous immersion in water. However, avoid intentionally submerging the indoor monitor.
- Solar Charging: Ensure the solar panel on the floating thermometer is kept clean and free of debris to maximize charging efficiency.
- Storage: If storing the device for an extended period, ensure the floating thermometer is fully charged and remove batteries from the indoor monitor. Store in a cool, dry place.
8. Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| No temperature reading on indoor monitor | No power to indoor monitor; Thermometer battery low; Out of wireless range; Pairing issue. | Check/replace AAA battery in indoor monitor. Ensure thermometer is solar charged. Move units closer. Restart both units. |
| Inaccurate temperature reading | Thermometer not fully immersed; Sensor obstructed; Calibration issue. | Ensure thermometer is fully submerged. Clean sensor area. Compare with another known accurate thermometer. |
| Short battery life (thermometer) | Insufficient solar exposure; Faulty battery. | Ensure solar panel is clean and exposed to direct sunlight for several hours daily. Contact support if issue persists. |
| Display is dim or blank | Low battery. | Charge the floating thermometer via solar power. Replace AAA battery in the indoor monitor. |
