Setting the Timer:

The timer uses ON (blue) and OFF (red) trippers to control the lighting schedule. These trippers are inserted into the slots around the dial.

1. Set ON Time: Insert a blue tripper into the dial at the desired time you want your lights to turn ON.
2. Set OFF Time: Insert a red tripper into the dial at the desired time you want your lights to turn OFF.
3. Set Current Time: The dial rotates counter-clockwise. To advance the clock, turn the dial clockwise until the present time is aligned with the arrow indicator.
4. Adjust for Daylight/Power Outage: Periodically check the time and adjust as needed to account for daylight saving changes or after any power outages.

5. Maintenance

The Intermatic LV371T transformer requires minimal maintenance to ensure long-lasting performance:

• Cleaning: Periodically wipe the exterior of the transformer with a damp cloth to remove dirt and debris. Ensure the unit is unplugged before cleaning.
• Connection Check: Annually inspect all electrical connections for tightness and signs of corrosion.
• Ventilation: Ensure that the ventilation slots (if present) are clear of obstructions to allow for proper heat dissipation.

6. Troubleshooting

If your lighting system is not operating as expected, consider the following troubleshooting steps:

• Lights Not Operating:
  • Check All Connections for Fault: Ensure the transformer is securely plugged into the outlet and all low-voltage lighting connections are tight and correct.
  • Verify that the circuit breaker or GFCI outlet supplying power to the transformer has not tripped.
  • Confirm that the ON tripper is correctly placed on the timer dial and the current time is accurately set.
• Lights Staying On/Off Continuously:
  • Check the placement of both ON and OFF trippers on the timer dial. Ensure they are firmly seated in their respective slots.
  • Verify that the current time on the dial is correctly aligned with the arrow indicator.
• Timer Not Advancing:
  • Ensure the transformer is receiving continuous power.
  • Inspect the timer mechanism for any obstructions or debris.
