Manual Control (ON/AUTO/OFF):
The MANUAL C/R button allows you to temporarily override programmed settings or switch between operating modes:
- Press MANUAL C/R repeatedly to cycle through the following modes:
- ON: The connected device will remain continuously ON, ignoring all programmed OFF times.
- OFF: The connected device will remain continuously OFF, ignoring all programmed ON times.
- AUTO: The timer will operate according to the programmed ON/OFF schedules. This is the standard operating mode for automated control.
Maintenance
- Clean the timer's exterior with a dry, soft cloth. Do not use abrasive cleaners, solvents, or liquids.
- Ensure the internal battery is charged periodically by connecting the timer to power, especially if the device is stored for extended periods without use.
- Regularly inspect wiring connections to ensure they remain secure and free from corrosion.
Troubleshooting
Common Issues and Solutions:
- Timer not turning ON/OFF as programmed:
- Verify that the timer is set to AUTO mode.
- Double-check all program settings (ON/OFF times and selected days of the week) for accuracy.
- Ensure the internal battery is sufficiently charged.
- Display is blank or unreadable:
- Check the main power supply to the timer.
- Confirm that the internal battery is charged. If the timer has been without power for a long time, it may need to charge for a few minutes before the display becomes active.
- "a" character appears in the lower left corner of the display:
- This indicates that the control switch is locked. To unlock, press the MANUAL C/R button four times in quick succession.
