Operation and Programming

Programming ON/OFF Events

The HB880R allows for up to 14 ON/OFF events (7 ON and 7 OFF pairs) per week, providing flexible scheduling for your devices.

Press the SET ON/OFF EVENTS button. The display will show "ON 1".
Use the + and - buttons to set the desired ON time for the first event. You can select a specific time (hour and minute) or choose "Dusk" for the astronomic setting. Press SET ON/OFF EVENTS to confirm.
Next, select the day(s) for this ON event. Use + and - to cycle through options like a single day, weekdays, weekends, or everyday. Press SET ON/OFF EVENTS to confirm.
The display will now show "OFF 1". Use + and - to set the corresponding OFF time for the first event. You can select a specific time or choose "Dawn" for the astronomic setting. Press SET ON/OFF EVENTS to confirm.
Repeat steps 2-4 for additional ON/OFF events (up to 7 pairs). Each pair will be labeled sequentially (ON 2/OFF 2, ON 3/OFF 3, etc.).
To exit programming mode at any time, press the SELECT FUNCTION button or wait for the timer to automatically return to normal operation after a period of inactivity.

Selecting Operating Modes

Press the SELECT FUNCTION button repeatedly to cycle through the available operating modes:

ON: The timer remains continuously ON, overriding any programmed events.

AUTO ON: The timer is currently ON and will follow the next scheduled OFF event, then resume normal programming.
AUTO OFF: The timer is currently OFF and will follow the next scheduled ON event, then resume normal programming.
RANDOM (RDM): Activates a random setting, turning connected devices ON/OFF within approximately 30 minutes of your programmed times. This feature is useful for simulating occupancy to enhance security.

Troubleshooting

Common Issues and Solutions

Display is Dim or Blank: Ensure the timer is properly plugged into a live electrical outlet. The internal AA battery is for memory backup only and does not power the display during normal operation.
Timer Not Activating/Deactivating as Programmed:
- Verify that the timer is set to "AUTO" mode (not ON or OFF override).
- Double-check all programmed ON/OFF times for accuracy, including AM/PM settings.
- Ensure the correct days of the week are selected for each event.
- Confirm that the connected appliance or light is working correctly and is properly plugged into the timer's outlets.
Astronomic Feature (Dusk/Dawn) Not Working Accurately: Ensure the current date and time are set correctly on the timer. The astronomic feature relies on accurate timekeeping to calculate local sunrise and sunset times.
Loss of Programming: If power is lost for an extended period and the internal AA battery is depleted or not installed, programmed settings may be lost. Re-program the timer following the instructions in the "Operation and Programming" section.
Buttons Unresponsive: Try pressing the RESET button to clear any temporary software glitches. If the issue persists, ensure the unit is receiving power.
