Setup and Programming

The Intermatic EJ341C timer allows for 24 daily ON/OFF settings and includes a random mode for enhanced security.

Setting the Current Time

1. Locate the time dial on the timer.
2. Rotate the dial clockwise until the current time aligns with the "TIME SET" arrow or indicator.

Programming ON/OFF Times

The timer uses small pins or segments around the dial to set ON and OFF times. Push segments inwards for ON times and leave them outwards for OFF times.

1. Identify the segments corresponding to the desired ON and OFF times throughout the 24-hour cycle.
2. Push the segments inwards for the periods you want the light to be ON.
3. Ensure segments are pulled outwards for the periods you want the light to be OFF.
4. The timer will automatically repeat this pattern daily.

Random ON/OFF Feature

To activate the random ON/OFF pattern, refer to the specific instructions provided with your timer. This feature slightly varies the programmed ON/OFF times to create a less predictable lighting schedule, enhancing security.

Operating Instructions

Manual Override

The EJ341C timer includes a manual override option. This allows you to temporarily turn the connected light ON or OFF without affecting the programmed schedule. Locate the manual override switch or button on the timer and toggle it as needed. The timer will resume its programmed schedule at the next scheduled ON or OFF event.

Memory Guard

The timer is equipped with a memory guard feature that protects your programmed settings against power failure. In the event of a power outage, your settings should be retained once power is restored.

Maintenance
