Setup and Installation

Safety Precaution: Before beginning installation, ensure that the main power supply to the circuit is turned off at the breaker to prevent electrical shock.

Wiring the Module:
- Connect the 220V FireWire to the terminal marked L.
- Connect the 220V Zero Line to the terminal marked N.
- The output terminals are passive. Connect your load (e.g., light, fan) to the appropriate output terminals (typically marked NO, COM, NC for Normally Open, Common, Normally Closed) based on your desired switching behavior. Refer to the wiring diagram provided with your specific unit if available.
Learning Remote Controls:
The module supports learning commonly used 315M wireless remote controls. The D1 indicator serves as both a receive indicator and a learning indicator.
- Press the learning button on the module (usually a small button near the D1 indicator). The D1 indicator will light up or flash, indicating it's in learning mode.
- While the indicator is active, press any button on your 315M remote control that you wish to pair.
- The D1 indicator will flash a few times and then turn off, indicating successful pairing.
- Repeat for additional remote control buttons if desired, or for multiple remote controls.
Setting Work Modes (Jog, Self-locking, Interlocking):
The work mode is typically set by jumpers or a dedicated button on the module. Consult the specific markings on your module for exact configuration.
- Jog Mode (Momentary): The relay activates only while the remote button is pressed and deactivates when released.
- Self-locking Mode (Toggle): Press the remote button once to activate the relay, press it again to deactivate.
- Interlocking Mode (Latched): Used with multiple buttons on a remote. Pressing one button activates its corresponding relay and deactivates any other active relays in the group.
Note: The exact method for setting these modes varies by module version. Look for jumpers (e.g., JP1, JP2) or a mode selection button.

Operating Instructions

Once the module is wired and remote controls are paired, operation is straightforward:

Power On: Restore power to the circuit. The module should be ready for operation.
Remote Control Operation:
- Press the paired button on your 315M remote control.
- The D1 indicator on the module will light up briefly, confirming reception of the signal.
- The connected load will respond according to the set work mode (Jog, Self-locking, or Interlocking).
Range: The remote control distance is typically 10-100 meters, depending on environmental factors and obstacles (e.g., walls).

Maintenance

The 315M Wireless Smart Switch is designed for low maintenance. Follow these guidelines to ensure longevity:

Cleaning: Use a dry, soft cloth to clean the exterior of the module. Do not use liquid cleaners or solvents.
Environment: Ensure the module is installed in a dry environment, away from excessive heat, humidity, and direct sunlight.
Power Supply: Ensure the input voltage remains within the specified AC110~220V range.
Load Capacity: Do not exceed the maximum load power of 10A to prevent damage to the module.

Troubleshooting

Problem	Possible Cause	Solution
Module does not respond to remote control.	Remote control not paired. Remote control battery is low or dead. Module not powered. Interference from other wireless devices. Remote control out of range.	Re-pair the remote control following the "Learning Remote Controls" section. Replace remote control batteries. Check power connections to the module. Move module or remote away from other wireless devices. Move closer to the module.
Load does not turn on/off correctly.	Incorrect wiring of the load. Load exceeds 10A capacity. Incorrect work mode setting.	Verify load wiring according to the "Setup and Installation" section. Ensure load does not exceed 10A. Check and adjust the work mode setting (Jog, Self-locking, Interlocking).
D1 indicator does not light up during learning.	Module not powered. Learning button not pressed correctly.	Check power connections. Ensure the learning button is pressed firmly and held for the required duration.
