5. Installation

Before you begin: Ensure power is OFF at the circuit breaker. This device is designed for single-pole applications and does not require a neutral wire, but a ground wire is mandatory.

1. Turn Off Power: Locate the circuit breaker controlling the switch you are replacing and turn it OFF. Verify power is off using a voltage tester.
2. Remove Old Switch: Carefully remove the existing wall plate and unscrew the old switch from the wall box. Disconnect the wires from the old switch.
3. Identify Wires: In a typical single-pole setup without a neutral wire, you will find:
   • HOT (Line) Wire: This wire brings power from the circuit breaker.
   • LOAD Wire: This wire carries power to the light fixture or appliance.
   • GROUND Wire: Typically bare copper or green insulated.

   Note: If you are unsure about wire identification, consult a qualified electrician.

4. Wire the Timer Switch: Connect the wires from the wall box to the timer's terminals using the provided wire nuts.
   • Connect the HOT (Line) wire from the wall box to the timer's HOT terminal (usually black).
   • Connect the LOAD wire from the wall box to the timer's LOAD terminal (usually red).
   • Connect the GROUND wire from the wall box to the timer's GROUND terminal (green).

5. Mount the Switch: Carefully push the wired switch into the wall box. Secure it with the mounting screws. Attach the wall plate.
6. Restore Power & Warm-Up: Turn the power back ON at the circuit breaker. The timer requires a warm-up period of 1-2 minutes after installation before the display activates and programming can begin. If the display does not appear immediately, wait for the specified warm-up time.

6.1 Button Functions

• MODE: Switches between manual and automatic modes. Used to delete individual settings during programming.
• DAY: Sets the current day of the week. Used for programming ON and OFF times for specific days.
• HOUR: Sets the current hour. Used for programming ON and OFF times.
• MIN: Sets the current minute. Used for programming ON and OFF times.
• PROG: Enters programming mode to set the clock (CLK) and up to 18 ON/OFF setting pairs (SCH).
• MAN (Manual Override): Allows manual ON/OFF control of the connected load, overriding current program settings temporarily.
• RESET (R): Clears all programming and resets the clock. Use a small pointed object to press.
• ON/OFF Switch: A physical switch to manually turn the connected device ON or OFF.

6.2 Setting Current Time and Day

1. Press the DAY button repeatedly to set the current day of the week.
2. Press the HOUR button repeatedly to set the current hour (AM/PM).
3. Press the MIN button repeatedly to set the current minute.
4. Ensure the display shows the correct AM/PM indicator.

6.3 Programming ON/OFF Schedules

The timer allows for up to 18 ON/OFF programs over a 7-day period. Programs can be set for specific days, weekdays, weekends, or daily.

1. Press the PROG button once to enter programming mode. The display will show "1 ON".
2. Press DAY to select the desired day(s) for this program (e.g., MO, TU, WE, TH, FR, SA, SU, or combinations like MO-FR, SA-SU, MO-SU).
3. Press HOUR and MIN to set the desired ON time for program 1.
4. Press PROG again. The display will show "1 OFF".
5. Press DAY to select the same day(s) as the ON time.
6. Press HOUR and MIN to set the desired OFF time for program 1.
7. Repeat steps 1-6 for additional programs (up to 18).
8. After setting all desired programs, press the MODE button to exit programming mode and return to normal operation. The display should show "AUTO".

6.4 Manual Override (MAN)

Press the MAN button to temporarily override the current program. This will switch the connected load ON or OFF. The timer will resume its programmed schedule at the next scheduled ON or OFF event.

6.5 Random Mode

The random mode feature can be used to deter intruders by turning lights ON and OFF at irregular intervals when you are away. Consult the full manual for specific instructions on activating and deactivating random mode, as it typically involves a combination of button presses.

7. Troubleshooting

• Display is blank after installation:

  The timer requires a 1-2 minute warm-up period after power is restored. If the display remains blank after this period, ensure the circuit breaker is ON and check wiring connections. Press the RESET button with a small pointed object.

  Image: Explains potential issues if the warm-up period is skipped, such as no display, timer malfunction, or flickering lights.

• Timer does not turn ON/OFF at scheduled times:

  Verify that the current time and day are set correctly. Check that the program settings (ON/OFF times and days) are entered accurately. Ensure the timer is in "AUTO" mode. If the issue persists, try resetting the timer using the RESET button and reprogramming.

• Lights flicker or do not turn on with low-wattage loads:

  This can sometimes occur with certain LED or low-wattage loads. Ensure the total wattage of the connected load is within the timer's specifications. If flickering occurs, it may indicate an incompatibility or a need for a minimum load. Consult the manufacturer's support if the problem persists.

• Timer resets unexpectedly:

  This could be due to a power fluctuation or incorrect wiring. Double-check all wiring connections, especially the HOT and LOAD wires. The built-in Ni-MH battery should retain settings during brief power outages, but prolonged outages or wiring issues can cause resets.

8. Maintenance

• Clean the timer switch and wall plate with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Periodically check for loose connections or signs of wear.
• The internal Ni-MH battery is designed for long life and typically does not require replacement.
