Operating Instructions
1. Power On/Off
The device powers on automatically after battery installation. There is no manual power off button; remove batteries to power down.
2. Temperature Unit Selection (℃/℉)
Press the ℃/℉ button on the indoor console to switch between Celsius and Fahrenheit temperature displays.
3. Setting Time and Alarm
Refer to the specific button functions on your indoor console (typically 'SET' or 'MODE') to adjust the time and set the alarm clock function. The alarm clock function helps organize your time.
4. Understanding Display Readings
- Water Temperature: Displays the current temperature from the floating sensor.
- Indoor Temperature: Displays the ambient temperature at the indoor console's location.
- MAX/MIN Record: Press the 'MIN/MAX' button to view the highest and lowest recorded temperatures over a 24-hour period. Press again to cycle through or clear.

5. High/Low Temperature Alarm
The indoor console allows you to set high and low temperature alerts for the water temperature. If the water temperature exceeds or falls below your set thresholds, an alarm will sound to promptly indicate the condition.
6. Wireless Communication
The wireless remote control thermometer utilizes 433MHz technology. The transmission distance is up to 300ft (100m) in open space and approximately 100ft (30m) under most conditions, allowing you to monitor temperatures remotely.

Maintenance
- Cleaning: Wipe both the indoor console and the floating sensor with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace batteries in both units when the low battery indicator appears on the display. Ensure the floating sensor's cover is securely tightened after battery replacement to maintain its waterproof integrity.
- Storage: If storing the thermometer for an extended period, remove all batteries from both units to prevent leakage and damage. Store in a cool, dry place.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on indoor console | Dead or incorrectly inserted batteries. | Check battery polarity; replace with fresh AAA batteries. |
| No water temperature reading / '---' displayed | Sensor batteries dead or incorrectly inserted; sensor out of range; interference; pairing lost. | Replace sensor batteries; move console closer to sensor; remove sources of interference; re-initiate pairing by holding 'CH+' on console. |
| Inaccurate temperature reading | Sensor not fully submerged; sensor placed near heat/cold source; low batteries. | Ensure sensor floats freely in the water; reposition sensor away from direct sunlight or pumps; replace batteries. |
| Alarm not sounding | Alarm settings incorrect; alarm volume too low (if adjustable). | Verify high/low alarm thresholds are set correctly; check for mute function. |
