When it comes to automating outdoor lighting, the Intermatic timer is a popular choice for homeowners. With its user-friendly interface and reliable performance, the Intermatic timer makes it easy to set up and maintain an automated lighting schedule. However, if you’re new to using this device, setting it up for the first time can seem like a daunting task. In this article, we’ll guide you through the process of setting an old Intermatic timer, providing step-by-step instructions and troubleshooting tips to ensure a smooth setup.
Before you begin, it’s important to gather the necessary tools and materials. You’ll need a screwdriver, a Phillips head screwdriver, and a pair of needle-nose pliers. You’ll also need to have the user manual for your specific Intermatic timer model on hand for reference. Once you have everything you need, let’s get started with the setup process.
First, locate the circuit breaker or fuse that controls the power to the outdoor lighting you want to automate. Turn off the power to the circuit breaker or fuse, and then remove the faceplate of the Intermatic timer. Next, use the screwdriver to remove the two screws that hold the timer in place. Carefully pull the timer out of the electrical box and set it aside. Now, you’re ready to start setting up the timer.
Identify the Timer Model
Locate the Model Number:
- The model number is typically printed on a label attached to the timer’s body.
Understand Model Naming Conventions:
- Intermatic timer model numbers typically follow a specific format: "T101/T101C" or "T104/T104C."
Table of Common Intermatic Timer Models:
| Model Number | Description |
|---|---|
| T101 | Basic 24-hour mechanical timer |
| T101C | 24-hour mechanical timer with manual override |
| T104 | 7-day mechanical timer |
| T104C | 7-day mechanical timer with manual override |
Additional Identification Tips:
- If the timer is missing its label, you can still identify its model by comparing its physical characteristics to images of different Intermatic models available online.
- You can also contact Intermatic customer support for assistance in identifying the timer model.
Shut Off Power to the Timer
1. Locate the circuit breaker or fuse box that controls the power to the timer. This is usually located in the basement or garage.
2. Turn off the circuit breaker or remove the fuse that corresponds to the timer. To turn off a circuit breaker, flip the switch to the “off” position. To remove a fuse, pull it straight out of the fuse box.
3. Test the power to the timer. Use a voltage tester to check if there is power going to the timer. If there is no power, the timer is not receiving power and you will need to troubleshoot the problem.
Troubleshooting Power Problems
| Problem | Solution |
|---|---|
| No power to the timer | Check the circuit breaker or fuse that controls the power to the timer. If the circuit breaker is tripped or the fuse is blown, reset or replace it. |
| Timer is not receiving power | Check the wiring connections to the timer. Make sure that the wires are securely connected and that there are no loose or damaged wires. |
Remove the Old Timer
To remove the old timer, follow these steps:
1. Turn off the power to the timer at the breaker panel.
2. Remove the faceplate of the timer by unscrewing the screws that hold it in place.
3. Disconnect the wires from the timer.
– There will be two or three wires connected to the timer: a black wire (hot), a white wire (neutral), and sometimes a red or blue wire (load).
– Use a screwdriver to loosen the screws that hold the wires in place, and then pull the wires off of the timer terminals.
4. Remove the timer from the electrical box.
– There will be two or three screws that hold the timer in place.
– Use a screwdriver to remove the screws, and then carefully pull the timer out of the electrical box.
5. Dispose of the old timer according to your local regulations.
Install the Mounting Plate
The mounting plate must be installed first, before the timer can be attached.
To install the mounting plate:
- Turn off the power to the circuit that the timer will control.
- Remove the faceplate from the timer.
- Connect the wires from the timer to the corresponding terminals on the mounting plate.
- Mount the plate to the wall using the screws provided.
- Reattach the faceplate to the timer.
Mounting the Plate to a Gang Box
If you are mounting the plate to a gang box, you will need to use the spacers provided. The spacers will help to center the plate in the box.
To mount the plate to a gang box:
- Place the spacers on the mounting screws.
- Insert the mounting screws into the gang box.
- Tighten the screws until the plate is secure.
Mounting the Plate to a Flat Surface
If you are mounting the plate to a flat surface, you will need to use the screws provided.
To mount the plate to a flat surface:
- Drill pilot holes for the screws.
- Insert the screws into the pilot holes.
- Tighten the screws until the plate is secure.
| Mounting Type | Spacers |
|---|---|
| Gang Box | Use spacers with mounting screws |
| Flat Surface | Do not use spacers |
Connect the Wires to the New Timer
Once you have the new timer in place, it’s time to connect the wires. This can be a bit tricky, but if you follow the instructions carefully, you can do it yourself.
Here’s how to do it:
1.
Turn off the power to the circuit breaker that controls the timer.
2.
Remove the old timer from the wall.
3.
Connect the wires to the new timer according to the diagram that came with it. Most timers will have a diagram on the back of the unit that shows you which wire goes where.
4.
The wires are usually color-coded, but if they’re not, you can use a multimeter to identify them.
Here is a table that shows the most common wire colors and their corresponding functions:
| Wire Color | Function |
|---|---|
| Black | Hot wire |
| White | Neutral wire |
| Green or Bare Copper | Ground wire |
1.
Once you have connected the wires, turn the power back on and test the timer to make sure it’s working properly.
Mount the New Timer
Once the old timer has been removed, you can proceed to mount the new timer. Follow these steps:
1. Align the mounting holes of the new timer with the holes on the electrical box.
2. Insert the mounting screws through the holes and tighten them until the timer is securely fastened.
3. Connect the wires to the terminals on the timer. The terminals are typically color-coded for easy identification:
| Wire Color | Terminal Connection |
|---|---|
| Black | Line 1 (L1) |
| White | Neutral (N) |
| Red | Line 2 (L2) from the load |
4. Tighten the terminal screws to secure the wires.
5. Replace the faceplate of the timer by aligning the tabs on the faceplate with the slots on the timer and snapping it into place.
6. Finally, turn on the power to the circuit and check if the timer is working correctly. If the timer does not power up, double-check the wiring connections to ensure they are correct and secure.
Set the Time
To set the current time, press the “Clock” button and turn the dial clockwise until the correct time is displayed. The indicator light will turn green once the time is set.
Program
