2. Safety Information
Observe the following safety guidelines to ensure proper operation and prevent hazards:
- This device is intended for use in dry locations only. Do not expose to water or excessive moisture.
- Maximum load capacity is 15 Amps. Do not exceed this rating.
- The product is ETL approved, ensuring compliance with safety standards.
- Always ensure the device is securely plugged into a functional electrical outlet.

3. Product Features
The HEATIT ET-24 is designed for automatic temperature control to protect against freezing:
- Thermostat Control: Automatically energizes connected devices when temperatures drop.
- Smart Indicator Light: A yellow light illuminates when the temperature is below 38°F (3°C) and the outlet is actively supplying power.
- Automatic Operation: Turns on below 38°F (3°C) and turns off at approximately 50°F (10°C).
- Energy Saving: Activates only when necessary, reducing energy consumption.
- Easy Installation: Simple plug-and-play design.
- Versatile Applications: Suitable for 120 VAC electric heaters, engine heaters, pipe heat tape, roof heating cables, and similar applications.

4. Setup and Installation
Follow these steps to set up your HEATIT ET-24 outlet:
- Ensure the installation location is dry and protected from moisture.
- Plug the HEATIT ET-24 directly into a standard 120 VAC electrical wall outlet.
- Connect your heating device (e.g., heat tape, electric heater) to one or both of the outlets on the HEATIT ET-24. The unit supports both 2-pin and 3-pin plugs simultaneously.
- Initial Test: To verify functionality upon receipt, place the unit in a freezer for approximately 45 minutes to reset its internal thermostat. After removing it from the freezer, plug it into a wall outlet. The yellow indicator light should illuminate, confirming the thermostat is active and the outlet is energized.

5. Operating Instructions
The HEATIT ET-24 operates automatically based on ambient temperature:
- Turn-on Temperature: The outlet will energize (turn on) when the ambient temperature drops below 38°F (3°C).
- Turn-off Temperature: The outlet will de-energize (turn off) when the ambient temperature rises to approximately 50°F (10°C).
- Indicator Light: A yellow indicator light will illuminate when the temperature is below 38°F (3°C) and the outlet is actively supplying power to the connected device. This light confirms the thermostat is working.


6. Maintenance
To ensure the longevity and optimal performance of your device:
- Keep the device clean and free from dust and debris. Use a dry cloth for cleaning.
- Do not attempt to open or repair the unit. Refer to qualified personnel for service.
- Store in a dry environment when not in use, especially during warmer seasons.
7. Troubleshooting
If you encounter issues with your HEATIT ET-24, consider the following:
- Device not turning on at low temperatures:
- Ensure the unit is securely plugged into a functional electrical outlet.
- Verify that the connected appliance is working correctly when plugged directly into a standard outlet.
- Perform a reset: Place the unit in a freezer for approximately 45 minutes. After removing, plug it into a wall outlet. The indicator light should turn on if the ambient temperature is below 38°F (3°C).
- Indicator light is on, but connected appliance is not heating:
- The indicator light confirms the outlet is energized. Check the connected appliance itself for proper function and ensure it is designed to operate at the current temperature.
- Device not turning off at higher temperatures:
- Ensure the ambient temperature has risen above 50°F (10°C). The device has a hysteresis to prevent rapid cycling.
- If the issue persists, perform a reset as described above.
