Operating Modes

The Enerlites HET01 timer switch has two primary operating modes: Manual and Automatic.

1. Automatic Mode

• In Automatic mode, the switch will operate according to your programmed ON/OFF schedules.
• To enter Automatic mode, ensure the small door is closed. The display will show "AUTO".
• The manual ON/OFF switch (located behind the door) should be in the "ON" or "OFF" position as desired for the initial state, but the programmed schedules will take precedence.

2. Manual Mode

• To manually turn the connected load ON or OFF, use the small toggle switch labeled "ON" and "OFF" located behind the door.
• Alternatively, when the door is closed, the main face of the switch acts as a manual button. Pressing the lower part of the switch will toggle the load ON or OFF. The display will show "MAN" when in manual override.
• The manual override will temporarily suspend the programmed schedule until the next scheduled event or until the mode is changed back to AUTO.

Maintenance

• Cleaning: To clean the switch, wipe with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Battery: The internal Ni-MH battery maintains time and program settings during power outages. This battery is typically long-lasting and not user-replaceable. If the timer consistently loses settings after power interruptions, the battery may need service by a qualified technician.
