Important Safety Instructions
WARNING: To reduce the risk of fire, electric shock, or personal injury, always follow these basic safety precautions:
- Read all instructions before using this product.
- Do not immerse the timer in water or expose it to extreme weather conditions beyond its outdoor rating.
- Ensure the timer is securely mounted or placed in a stable position to prevent accidental dislodgement.
- Do not exceed the electrical ratings of the timer (15A resistive, 8A tungsten, 1/3 HP).
- Always plug the timer into a grounded outdoor receptacle protected by a Ground Fault Circuit Interrupter (GFCI).
- Keep children away from the timer and connected devices.
- Unplug the timer from the power source before performing any maintenance or cleaning.
- Do not use with extension cords that are not rated for outdoor use.
Product Features
- Photosensitive Activation: Automatically detects dusk to initiate programmed timing.
- Interruption-Free Programming: External light sources (headlights, street lamps) will not interfere with the timer's operation once activated.
- Multiple Timing Modes: Selectable options for 2 hours, 4 hours, 6 hours, 8 hours, or Dusk-to-Dawn operation.
- Two Grounded Outlets: Control up to two devices simultaneously.
- Reverse Ground Pin Placement: Accommodates most right-angle and transformer plugs when wall-mounted.
- Compatibility: Works with CFL, LED, fluorescent, and incandescent bulbs.
- Durable Design: Suitable for outdoor use.
Setup and Installation
- Unpack the Timer: Carefully remove the timer from its packaging. Inspect for any damage.
- Choose a Location: Select an outdoor location that is protected from direct heavy rain and where the photocell (light sensor) will receive natural ambient light. Avoid locations where artificial light sources (e.g., porch lights, security lights) might shine directly onto the photocell, as this could interfere with its operation.
- Mounting (Optional): The timer can be wall-mounted using the integrated mounting slots on the back. Use appropriate screws (not included) for your mounting surface. Ensure the timer is mounted securely.

- Plug in the Timer: Insert the timer's grounded plug into a 120V AC outdoor GFCI-protected electrical outlet.
- Connect Devices: Plug your outdoor lights or appliances into the two grounded outlets on the timer. Ensure the total electrical load does not exceed the timer's maximum rating.
Operating Instructions
The POWER ZONE TNOCD002 timer features a simple turn-dial control for selecting operating modes.

- Power Indicator: A red LED light labeled "Power" will illuminate when the timer is receiving power.
- Select a Mode: Rotate the dial to choose one of the following operating modes:
- OFF: The timer will remain off, and connected devices will not receive power.
- ON: The timer will continuously supply power to connected devices, regardless of light conditions.
- 2 Hrs: Connected devices will turn on at dusk and remain on for 2 hours.
- 4 Hrs: Connected devices will turn on at dusk and remain on for 4 hours.
- 6 Hrs: Connected devices will turn on at dusk and remain on for 6 hours.
- 8 Hrs: Connected devices will turn on at dusk and remain on for 8 hours.
- Dusk-Dawn: Connected devices will turn on at dusk and remain on until dawn.
- Photosensitive Operation: For timed modes (2, 4, 6, 8 Hrs, and Dusk-Dawn), the timer uses its built-in photocell to detect when ambient light levels drop (dusk). Once dusk is detected, the selected countdown or dusk-to-dawn cycle begins. The timer will automatically reset for the next cycle after the current programming cycle has completed.
- Interruption Protection: The timer is designed to prevent interference from temporary light sources like car headlights or street lamps once a cycle has begun.
Maintenance
- Cleaning: Disconnect the timer from the power source before cleaning. Wipe the exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Inspection: Periodically inspect the timer, cord, and plugs for any signs of damage, wear, or corrosion. If damage is found, discontinue use and replace the unit.
- Photocell: Ensure the photocell sensor is clean and unobstructed for proper operation.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Timer does not turn on. | No power to the outlet. Timer is set to "OFF". Faulty timer. | Check the power outlet and GFCI. Rotate the dial to an "ON" or timed setting. Discontinue use and replace. |
| Connected devices do not turn on at dusk. | Photocell is obstructed or receiving too much light. Timer is set to "OFF" or "ON". Devices are faulty or unplugged. | Relocate the timer or clear obstructions from the photocell. Ensure it's not exposed to artificial light. Set the dial to a timed mode (2, 4, 6, 8 Hrs, or Dusk-Dawn). Check connected devices and their connections. |
| Devices stay on continuously or turn off too early/late. | Timer is set to "ON". Photocell is malfunctioning or exposed to inconsistent light. | Rotate the dial to a timed mode. Ensure the photocell is clean and in a location with consistent natural light. If issues persist, the unit may be faulty. |
