• Connect the incoming 120V AC power supply to the designated input terminals.
• Connect the load (e.g., lighting, motor) to the output terminals. The contact type is Normally Open (NO).
• Ensure all wire connections are tight and secure to prevent loose connections and potential hazards.
• If integrating with Insteon or X-10 systems, follow the specific wiring and configuration instructions for those protocols.

After wiring, replace the cover and restore power at the circuit breaker.

6. Operating Instructions

The ET70115C is designed for automatic operation based on programmed schedules. Programming details will vary depending on the specific model's interface (buttons, display) and remote control integration.

6.1 Initial Power-Up

Upon initial power-up, the device may require setting the current time and date. Consult the on-screen prompts or specific programming section for your model.

6.2 Programming Schedules

The time switch allows for multiple ON/OFF events per day or week. Access the programming menu (usually via a 'Menu' or 'Program' button) and follow the on-screen instructions to set desired schedules. Each event typically requires a start time and an end time.

6.3 Remote Control (Insteon/X-10)
