5. Safety Information

Please read and understand all safety instructions before installing or operating this device. Failure to follow these instructions may result in electric shock, fire, or property damage.

• Electrical Hazard: Installation should only be performed by a qualified electrician or knowledgeable individual. Ensure power is disconnected at the circuit breaker before any wiring.
• Voltage Compatibility: Verify that the voltage of your electrical system matches the operating voltage range of the switch (AC 100V-240V).
• Load Capacity: Do not exceed the maximum load current of 30 Amps. Overloading can cause overheating and fire.
• Proper Wiring: Ensure all wire connections are secure and correctly terminated to prevent short circuits or loose connections.
• Environmental Conditions: Do not expose the device to moisture, extreme temperatures, or corrosive environments.

6. Installation and Wiring

The receiver unit must be wired into your electrical circuit. Always ensure power is OFF before beginning installation.

6.1 Basic Wiring Overview

6.2 Wiring for Single Phase 110V/120V Application

1. Connect the red wire from your AC input to the 'L' terminal of the receiver's AC Input.
2. Connect the black wire from your AC input to the 'N' terminal of the receiver's AC Input.
3. Connect the red wire from the receiver's AC Output 'L' terminal to the 'L' terminal of your equipment/load.
4. Connect the black wire from the receiver's AC Output 'N' terminal to the 'N' terminal of your equipment/load.
5. Ensure the green ground wire from your input connects to the equipment's green ground wire.

6.3 Wiring for Single Phase 240V or 3 Phase Voltage Application (with AC Contactor)

For higher voltage or 3-phase applications, an external AC Contactor is required to handle the main load. The wireless switch will control the contactor's coil.

1. Connect the red wire from your AC input (e.g., L1) to the 'L' terminal of the receiver's AC Input.
2. Connect the black wire from your AC input (e.g., L2 or Neutral) to the 'N' terminal of the receiver's AC Input.
3. Connect the red wire from the receiver's AC Output 'L' terminal to one side of the AC Contactor's coil (e.g., A1).
4. Connect the black wire from the receiver's AC Output 'N' terminal to the other side of the AC Contactor's coil (e.g., A2).
5. Wire the main 240V or 3-phase power through the main contacts of the AC Contactor to your equipment/load.

7. Operating Modes

The receiver supports three primary operating modes: Momentary, Toggle, and Latched. The specific mode is set during the pairing process.

7.1 Momentary Mode

In Momentary mode, the relay activates only while the remote button is pressed and held. Releasing the button deactivates the relay.

• Operation: Press and hold remote button → Relay ON; Release remote button → Relay OFF.
• Application: Ideal for applications requiring temporary activation, such as electric door openers or momentary pump control.

7.2 Toggle Mode

In Toggle mode, each press of the remote button alternates the relay state between ON and OFF.

• Operation: Press remote button → Relay ON; Press same button again → Relay OFF.
• Application: Suitable for standard ON/OFF control of lights, fans, or other appliances.

7.3 Latched Mode

Latched mode requires two distinct buttons on the remote. One button turns the relay ON, and another button turns it OFF.

• Operation: Press Button A → Relay ON; Press Button B → Relay OFF.
• Application: Useful for specific ON/OFF controls where distinct buttons are preferred, such as roller blind doors (up/down).

8. Pairing Remote Control (Learning Mode)

To pair a remote control with the receiver and set its operating mode:

1. Momentary Mode Setup:
   • Press the learning button on the receiver once. The LED indicator will flash once.
   • Immediately press the desired button on your remote control. The LED indicator will flash multiple times, indicating successful pairing in Momentary mode.
2. Toggle Mode Setup:
   • Press the learning button on the receiver twice. The LED indicator will flash twice.
   • Immediately press the desired button on your remote control. The LED indicator will flash multiple times, indicating successful pairing in Toggle mode.
3. Latched Mode Setup:
   • Press the learning button on the receiver three times. The LED indicator will flash three times.
   • Immediately press the 'ON' button (e.g., Button A) on your remote control.
   • After 3 seconds, press the 'OFF' button (e.g., Button B) on your remote control. The LED indicator will flash multiple times, indicating successful pairing in Latched mode.

9. Resetting the Receiver

To clear all paired remote controls from the receiver's memory:

1. Long press the learning button on the receiver for approximately 8 seconds.
2. The LED indicator will flash rapidly and then turn off, indicating that all previously learned transmitters have been cleared.
3. After a reset, all remote controls will no longer function and must be re-paired using the learning procedure described in Section 8.
