Operating Instructions
Initial Setup and Time Setting
- Upon initial power-up or after a power outage, the display will prompt you to set the time and date.
- Use the programming buttons (usually located under a small cover or on the side) to navigate and adjust the hour, minute, AM/PM, year, month, and day. Refer to the on-screen prompts.
- Confirm each setting to proceed.
Programming Schedules
The timer allows for multiple ON/OFF events per day. It also features an astronomic clock that automatically adjusts for sunrise and sunset times based on your geographical location (which may need to be set during initial setup).
- Enter Programming Mode: Press the "PROG" button (or similar, consult on-screen menu).
- Select Event: Choose an available program slot (e.g., P1 ON, P1 OFF).
- Set Time: Adjust the hour and minute for the ON or OFF event.
- Select Days: Choose which days of the week the program should be active (e.g., Mon-Fri, Sat-Sun, Everyday, or specific days).
- Astronomic Feature: If desired, select "Dusk" or "Dawn" for events to automatically follow sunrise/sunset. You may need to input your geographical region or zip code for accurate astronomic times.
- Save: Confirm and save the program. Repeat for all desired ON/OFF events.
Manual Override
To manually turn the connected load ON or OFF without affecting the programmed schedule, simply press the large rocker switch on the front of the timer. The display will indicate "Manual ON" or "Manual OFF". The timer will revert to its programmed schedule at the next scheduled event.
Green LED Locator
The small green LED light on the timer serves as a locator light, making the switch visible in the dark. It also indicates the status of the connected load (e.g., ON/OFF, or if a program is active).
Maintenance
The Leviton VPT24-1PZ timer requires minimal maintenance.
- Cleaning: To clean the surface, wipe with a soft, damp cloth. Do not use abrasive cleaners, solvents, or sprays directly on the device.
- Battery Backup: The timer typically includes an internal battery to retain programming during short power outages. If the display is blank after a power outage, the battery may be depleted or the outage was prolonged. Reprogramming may be necessary.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Timer display is blank. | No power to the timer; internal battery depleted. | Check circuit breaker. Ensure neutral wire is correctly connected. Allow time for internal battery to recharge after power restoration. |
| Load does not turn ON/OFF as programmed. | Incorrect programming; manual override active; wiring issue. | Verify program settings (times, days). Check if manual override is engaged. Re-check wiring connections. |
| Timer does not respond to button presses. | Timer is locked; internal error. | Try a soft reset (if applicable, consult specific model instructions). Turn off power at breaker for 30 seconds, then restore. If problem persists, contact Leviton support. |
| Astronomic feature is inaccurate. | Incorrect geographical location or time zone setting. | Re-enter your geographical region, zip code, or latitude/longitude in the timer's settings. Ensure the current time and date are accurate. |
