4.3 Mounting
Mount the photocontrol in a location where it will receive unobstructed natural light throughout the day. Avoid areas where artificial light sources (e.g., streetlights, porch lights) might shine directly onto the sensor, as this could interfere with its operation.
5. Operating Instructions
The Design House 588079 Photocontrol operates automatically based on ambient light levels.
- Dusk Activation: When the ambient light level drops below a certain threshold (typically at dusk), the photocontrol will automatically turn on the connected lighting.
- Dawn Deactivation: When the ambient light level rises above a certain threshold (typically at dawn), the photocontrol will automatically turn off the connected lighting.
- Time Delay: The photocontrol incorporates a time delay feature to prevent false triggering from transient light changes (e.g., car headlights, lightning flashes). This means there will be a slight delay (typically a few seconds to a couple of minutes) between the change in light level and the activation or deactivation of the lights.

6. Maintenance
The Design House 588079 Photocontrol requires minimal maintenance.
- Cleaning: Periodically inspect the photocontrol sensor for any dirt, dust, or debris that may obstruct the light sensor. Gently clean the sensor surface with a soft, damp cloth. Do not use abrasive cleaners.
- Inspection: Annually inspect the wiring connections and the housing for any signs of wear, damage, or corrosion. Ensure the mounting is secure.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on at dusk. | No power, faulty wiring, sensor obstructed, sensor exposed to artificial light. | Check circuit breaker. Verify wiring connections. Clean sensor. Relocate photocontrol away from artificial light sources. |
| Lights do not turn off at dawn. | Sensor obstructed, sensor exposed to artificial light. | Clean sensor. Relocate photocontrol away from artificial light sources. |
| Lights flicker or cycle on/off rapidly. | Interference from nearby light, faulty connection. | Ensure sensor is not exposed to intermittent light. Check wiring connections for looseness. |
