Setting up an Intermatic timer can be a daunting task, but with the right information, it can be a breeze. This comprehensive guide will provide you with step-by-step instructions on how to install, wire, and program your Intermatic timer, ensuring that your lights, appliances, or other electrical devices are operating according to your desired schedule.
To begin, gather the necessary tools and materials. You will need the Intermatic timer, a screwdriver, electrical tape, and wire nuts. Ensure that you have a clear understanding of your electrical system and follow all safety precautions before starting the installation process. Locate a suitable location for the timer, considering factors such as accessibility, proximity to the devices you want to control, and protection from moisture and extreme temperatures.
Next, prepare the electrical wires by stripping the ends of the wires to expose approximately 1/2 inch of bare copper. Connect the wires to the appropriate terminals on the timer. Typically, the black wire is connected to the “Line” terminal, the white wire is connected to the “Load” terminal, and the green or bare wire is connected to the “Ground” terminal. Secure the connections by tightening the terminal screws and wrapping electrical tape around each connection to prevent shorts.
Wiring the Timer
Terminals
Locate the terminal block on the timer. Most Intermatic timers have four terminals: line (L), load (L1), neutral (N), and ground (GND).
Wire Connections
- Line (L): Connect the black or red wire from the electrical panel to the “L” terminal.
- Load (L1): Connect a wire from the device you want to control (e.g., light fixture, motor) to the “L1” terminal.
- Neutral (N): Connect the white wire from the electrical panel to the “N” terminal. This is the common return path for electricity.
- Ground (GND): Connect the bare or green wire from the electrical panel to the “GND” terminal. This provides a safety path for electrical current in case of a fault.
Special Wiring Considerations
For three-way switches, you will need to connect an additional wire from the switch to the “T” (Traveler) terminal on the timer.
For outdoor applications, use wire nuts approved for outdoor use and wrap the connections with electrical tape.

| Neutral (N) | White |
| Ground (GND) | Bare or Green |
Troubleshooting Common Issues
7. Timer Not Working
If your Intermatic timer is not working, there are a few things you can check:
- Check the power supply. Make sure that the timer is plugged into a working outlet and that the power switch is turned on.
- Check the wiring. Make sure that the wires are properly connected to the timer and to the load.
- Check the programming. Make sure that the timer is programmed correctly for the desired schedule.
- Reset the timer. If the timer is still not working, try resetting it by pressing the reset button.
- Replace the timer. If the timer is still not working after troubleshooting, it may need to be replaced.
| Possible Causes | Solutions |
|---|---|
| Blown fuse | Replace the fuse |
| Tripped circuit breaker | Reset the circuit breaker |
| Loose or damaged wiring | Tighten or repair the wiring |
| Faulty timer | Replace the timer |
Advanced Programming Options
Intermatic timers offer a range of advanced programming options to cater to specific user needs. These options provide enhanced control over the timing and duration of events, allowing for more complex and customizable schedules.
Randomization Feature
The randomization feature introduces variability into the timing of events, making it harder for intruders to predict when the lights will be on or off. This feature can enhance home security by deterring potential burglars.
|
Enabled: Events occur at unpredictable times within a set range. |
|
Disabled: Events occur at the exact time specified in the schedule. |
Multi-Event Programming
Advanced timers allow users to program multiple events for a single day or week. This feature is useful for situations where specific lighting or device operations need to occur at different times throughout the day.
|
Time-Based Events: Events triggered at specific times. |
|
Sun-Based Events: Events triggered based on sunrise/sunset times. |
|
Interval-Based Events: Events repeated at regular intervals throughout the day. |
Holiday Programming
Intermatic timers offer dedicated holiday programming capabilities. Users can temporarily override the regular schedule for specific days, such as holidays or vacations. This feature ensures that lighting or device operations are adjusted accordingly.
|
Temporary Schedule: Create a separate schedule for holiday periods. |
|
Disable Schedule: Suspend all scheduled events during the designated holiday. |
Astro Programming
Astro programming synchronizes the timer’s schedule with the sunrise and sunset times for a specific location. This feature ensures that lighting or device operations automatically adjust according to the changing natural daylight, optimizing energy efficiency.
How To Set Up Intermatic Timer
Setting up an Intermatic timer is not a difficult task, but there are a few things you need to do to ensure that it works properly. Here are the steps on how to set up an Intermatic timer:
- Turn off the power to the circuit that you will be connecting the timer to.
- Remove the faceplate of the timer by pressing the release button on the bottom of the timer.
- Connect the wires from the circuit to the terminals on the timer. The black wire goes to the “LINE” terminal, the white wire goes to the “LOAD” terminal, and the green wire goes to the “GND” terminal.
- Set the time and date on the timer. To do this, press the “SET” button on the front of the timer. Use the up and down arrows to adjust the time and date.
- Set the program for the timer. To do this, press the “PROG” button on the front of the timer. Use the up and down arrows to select the desired program.
- Press the “RUN” button on the front of the timer to start the program.
- Replace the faceplate on the timer.
- Turn on the power to the circuit.
