- Black Wire (277V): Connect to the incoming line voltage (hot) wire from the wall box.
- Red Wire: Connect to the load wire (to the light fixture or appliance).
- Yellow Wire: Typically used for 3-way applications or specific control functions. Refer to detailed wiring diagrams for your specific setup. If not used, cap off securely.
Use wire nuts to secure all connections. Ensure no bare wire is exposed.

- Secure the switch to the wall box using the provided mounting screws.
- Attach the wall plate (not included with the switch) over the switch.
4.4 Initial Power-Up
Once installation is complete, turn the power back ON at the circuit breaker. The device will undergo an initial warm-up period, which may take approximately 30 seconds, as indicated by the label on the device. The display should then illuminate.
5. Operation
The TS-200 Inteliswitch features a digital display and a central control button for interaction.
- Manual ON/OFF: Press the central button briefly to manually toggle the connected load ON or OFF. This will override any active program until the next scheduled event.
- Display: The digital display shows the current time, day, and operational status (e.g., ON/OFF, program mode).
6. Programming
Detailed programming instructions are typically accessed by pressing and holding the central button or a combination of button presses. Refer to the on-screen prompts for specific steps.
6.1 Setting Time and Date
Access the settings menu (usually by holding the main button). Use the button to navigate and adjust hours, minutes, day, month, and year. Confirm each setting to save.
6.2 Creating Schedules
The TS-200 allows for multiple ON/OFF programs. Navigate to the "Program" or "Schedule" menu. Select a program slot and set the desired ON time, OFF time, and the days of the week for the program to be active. Repeat for additional programs.
6.3 Operating Modes
The switch may offer various operating modes such as:
- Automatic: Follows programmed schedules.
- Manual: Stays ON or OFF until manually changed.
- Random: Varies ON/OFF times slightly for a lived-in look (e.g., for security).
- Holiday: Suspends normal programming for a set period.
Select the desired mode from the menu.
7. Maintenance
The TS-200 Inteliswitch requires minimal maintenance.
- Cleaning: Wipe the surface with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Internal Battery: The device contains an internal battery to maintain time and program settings during power outages. This battery is typically long-lasting and not user-replaceable. If the device consistently loses settings after power interruptions, professional service may be required.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
