Key Components:
- LCD Display: Shows current temperature, set temperature, and heating status for both P1 and P2.
- Menu Button (≡): Used to access settings and confirm selections.
- Down Button (∨): Decreases values or navigates menu options.
- Up Button (∧): Increases values or navigates menu options.
- P1/P2 Probe Sockets: Connect the temperature probes.
- WORK1/WORK2 Thermostat Sockets: Connect heating devices (e.g., heating mats).
- Hanging Tab: For convenient mounting of the unit.
5. Setup
- Placement: Choose a suitable location for the controller. It has a hanging tab for easy mounting. Ensure it is away from direct heat sources or excessive moisture.
- Connect Probes: Insert the two temperature probes into the P1 and P2 sockets on the sides of the controller. Place the probe tips in the desired temperature monitoring locations (e.g., soil for seedlings, inside a reptile enclosure). Use the included suction cups to secure the probes if needed.
- Connect Heating Devices: Plug your heating mats or other heating devices into the WORK1 and WORK2 outlets at the bottom of the controller. Ensure the total wattage for each outlet does not exceed 250W, and the combined total does not exceed 500W.
- Power On: Plug the controller's power cord into a standard 100-240VAC, 50/60Hz electrical outlet. The LCD display will light up.

6. Operating Instructions
6.1. Setting Target Temperature (P1/P2)
- Press the Menu (≡) button once. The P1 set temperature will flash.
- Use the Up (∧) or Down (∨) buttons to adjust the desired target temperature for P1.
- Press the Menu (≡) button again to confirm P1 setting and move to P2. The P2 set temperature will flash.
- Use the Up (∧) or Down (∨) buttons to adjust the desired target temperature for P2.
- Press the Menu (≡) button a third time to confirm P2 setting and exit the setting mode.

6.2. Switching Temperature Units (°C/°F)
To switch between Fahrenheit (°F) and Celsius (°C):
- With the unit in normal operating mode (not in setting mode), press and hold the Up (∧) button for approximately 3 seconds. The display will switch units. Repeat to switch back.

6.3. High/Low Temperature Alarms
The controller features audible alarms to alert you if the detected temperature falls outside your desired range or if a probe abnormality occurs.
- When the temperature exceeds the set high limit or drops below the set low limit, the alarm will sound.
- If a probe is disconnected or faulty, an alarm will also sound.
- To silence the alarm, press any button.

7. Maintenance
- Cleaning: Disconnect the controller from the power outlet. Wipe the unit and probes with a soft, damp cloth. Do not use abrasive cleaners or immerse the unit in water.
- Storage: When not in use for extended periods, store the controller in a cool, dry place, away from direct sunlight and extreme temperatures.
- Probe Care: Handle probes carefully. Avoid bending or kinking the cables. Clean probe tips regularly to ensure accurate readings.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank | No power; unit damaged. | Check power connection. Ensure outlet is functional. If still blank, contact support. |
| Heating device not turning on/off | Incorrect temperature settings; device not properly plugged in; device faulty. | Verify set temperatures. Ensure heating device is securely plugged into the correct outlet (WORK1/WORK2). Test heating device independently. |
| Temperature reading is inaccurate | Probe not properly placed; probe faulty; calibration needed. | Ensure probe tip is fully immersed or in direct contact with the medium. Check probe connection. Refer to the full user manual for calibration instructions if necessary. |
| Alarm sounds frequently | Temperature outside set range; probe abnormality. | Adjust temperature settings to a wider range if fluctuations are normal for your application. Check probe connections. |
