- Clear VA Display: Advanced VA display screen with self-illuminating font technology for clear readings in any lighting condition.
- Wide Range Temperature Control: Combines heating and cooling modes, with a range from -40℉ to 210℉ and 0.1℉ precision.
- Versatile Applications: Suitable for incubators, reptile rooms, greenhouses, home brewing, and maintaining constant indoor temperatures.
- Convenient & Efficient: Features power memory, temperature calibration, and multiple timing modes (Cyclic Timing, Countdown ON/OFF).
Setup
- Unpack the Device: Carefully remove the temperature controller and its accessories from the packaging.
- Connect the Sensor: Plug the temperature probe into the designated port on the side of the controller. Ensure it is securely connected.
- Placement of Sensor: Position the temperature probe in the environment where you wish to monitor and control the temperature. Ensure it is not directly exposed to heat sources or drafts that could skew readings.
- Plug into Power Outlet: Insert the controller's plug into a standard 120V AC power outlet. The VA display will illuminate.
- Connect Appliance: Plug your heating or cooling appliance (e.g., heater, fan) into the power outlet on the front of the temperature controller.

Operating Instructions
Setting Temperature Parameters:
The controller allows you to set a 'Start Temperature' (ON) and a 'Stop Temperature' (OFF) to maintain your desired range.
- Press the SET button once. The 'Start Temperature' (ON) value will begin to flash.
- Use the UP or DOWN buttons to adjust the desired 'Start Temperature'.
- Press the SET button again. The 'Stop Temperature' (OFF) value will begin to flash.
- Use the UP or DOWN buttons to adjust the desired 'Stop Temperature'.
- Press the SET button a third time to confirm your settings and exit the temperature setting mode.
The device will automatically switch between heating and cooling modes based on the set temperatures and the measured temperature. If the measured temperature falls below the 'Start Temperature', the connected appliance will activate (heating mode). If it rises above the 'Stop Temperature', the appliance will deactivate (cooling mode).

Timing Functions (FUN Button):
Press the FUN button to cycle through different timing modes (F01-F04). Press SET to enter the setting for each mode, and UP/DOWN to adjust values.
F01: Cyclic Timing Mode
This mode allows the device to cycle between ON and OFF states for set durations. Ideal for applications requiring periodic operation.

F04: Countdown ON/OFF Mode
The device will turn ON after an initial countdown, then turn OFF after a subsequent countdown period.
Display showing settings for Countdown ON/OFF Mode (F04), allowing for sequential ON and OFF countdowns.
Temperature Calibration:
If you notice a discrepancy between the controller's measured temperature and a known accurate thermometer, you can calibrate the device. Consult the full product manual or manufacturer's website for detailed calibration steps.
Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or immerse the unit in water.
- Sensor Care: Ensure the temperature probe is kept clean and free from debris. Avoid bending or damaging the probe cable.
- Storage: When not in use, store the controller in a cool, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank. | No power or power outage. | Check power connection. Ensure the outlet is functional. |
| Temperature reading is inaccurate. | Sensor dirty or damaged; needs calibration. | Clean the sensor. Perform temperature calibration as per advanced instructions. Replace sensor if damaged. |
| Appliance not turning ON/OFF as expected. | Incorrect temperature settings; timing mode active; appliance malfunction. | Verify 'Start' and 'Stop' temperature settings. Check active timing mode. Test the connected appliance directly. |
| Error message on display. | Sensor fault or internal error. | Unplug the device, wait 30 seconds, then plug it back in. If the error persists, contact customer support. |
