Package Include:
1 x Receiver: S2U-DC-ANT3
1 x User manual

Application:
This receiver is an electric device with 2 relay outputs, it and the transmitter form a wireless remote-control system. This system may be used in all types of industry automation, agriculture, business, home, factory, house, farm, garage, vehicle, ship, aerial vehicle, etc. It can remote control different DC or AC equipment on land, water, and air, such as lights, doors, windows, lamps, sockets, locks, sirens, outlets, heaters, motors, fans, winches, curtains, blinds, linear actuators, electric solenoid valves, and security alarm systems. The applications are endless.

Feature:
Wireless control, easy to install.
Waterproof: The receiver has waterproof case and waterproof connector, it can be installed outdoors.
Four operating voltage versions: DC 6V, 9V, 12V, 24V optional.
Relay Output: This receiver is dry relay output; it can be used to operate both DC and AC equipment. The output terminals are NO / NC (normally open / normally closed), serving as a switch. That means you should also connect a separate power supply to equipment.
Each channel can work at maximum current 10A, such as 120W/12V, 60W/6V, 90W/9V, 240W/24V, 1100W/110V, 2200W/220V.
With external antenna, the receiver has a farther working range.
The transmitter / remote can control the receiver from any place within a reliable working distance.
Wireless RF signal from the transmitter can pass through walls, floors, doors, or windows, but it will lose some operating range.
The receiver has reverse voltage protection and overcurrent protection.
The receiver can only be triggered by paired transmitters.
One or more transmitters / remotes can control one or several receivers simultaneously.
Two or more receivers may be used in the same area.

Matching Transmitters:
This receiver can work with different transmitters, such as model C-2 / C-3 (100M), CWB-2 / CWB-3 (50M, waterproof), or CB-2 / CWB-3 (1000M) etc.
When you set the receiver in Self-locking mode or Momentary mode, it should work with two buttons transmitter, such as model C-2 (100M), CWB-2 (50M, waterproof), or CB-2 (1000M) etc. When you set the receiver in Interlocking mode, it should work with three buttons transmitter, such as model C-3 (100M), CWB-3 (50M, waterproof), or CB-3 (1000M) etc.

Working Range:
The receiver and the transmitter (such as C-2) form a complete kit, the maximum working distance may reach 300 feet or 100 meters in an open area.
The maximum working distance is a theoretical data, it shall be operated in an open ground, no barriers, no interference. But in the practice, it will be hindered by trees, walls, or other construction, and will be interfered by other wireless signals. Therefore, the actual working distance may not reach this maximum distance.
If you want to have a further working range, you can use a powerful transmitter, such as CB-2 or CB-3 transmitter.

Usage:
The receiver can be used to control both 0~28VDC and 110~240VAC devices.
Notice: The receiver is relay output, not DC/AC power output. Initial state of relay output terminals: Terminals B and C are Normally Open; Terminals A and B are Normally Closed.

Wiring:
1. If you want to control a DC 12V lamp, do as following:
1) Connect the positive pole of DC power supply to terminal <L/+> of INPUT, and connect the negative pole of DC power supply to terminal <N/-> of INPUT.
2) Connect terminal B to the positive pole of DC power supply, connect terminal C to the positive pole of DC lamp, and connect the negative pole of DC lamp to the negative pole of DC power supply.

2. If you want to control an AC 120V or 220V lamp, do as following:
1) Connect the positive pole of DC power supply to terminal <L/+> of INPUT, and connect the negative pole of DC power supply to terminal <N/-> of INPUT.
2) Connect terminal B to the live wire of AC power supply, connect terminal C to one side of AC lamp, and connect another side of AC lamp to the neutral wire of AC power supply.

Setting different working modes:
The receiver will be set in Self-locking mode before leaving the factory, if you want to use another mode, please follow the following steps.

1) Setting Momentary mode: Only connect Jumper-1.
Mode Momentary (working with transmitter C-2): Press and hold -> On; Release -> Off.
Press and hold button A of the transmitter: The relay 1 is activated (connect the terminals B and C, disconnect the terminals A and B), and the lamp 1 is turned on.
Release button A: The relay 1 is deactivated (disconnect the terminals B and C, connect the terminals A and B), and the lamp 1 is turned off.
Press and hold button B of the transmitter: The relay 2 is activated (connect the terminals B and C, disconnect the terminals A and B), and the lamp 2 is turned on.
Release button B: The relay 2 is deactivated (disconnect the terminals B and C, connect the terminals A and B), and the lamp 2 is turned off.

2) Setting Self-locking mode:Only connect Jumper-2.
Mode Self-locking (working with transmitter C-2): Press -> On; Press again -> Off.
Press button A of the transmitter: The relay 1 is activated (connect the terminals B and C, disconnect the terminals A and B), and the lamp 1 is turned on.
Press button A again: The relay 1 is deactivated (disconnect the terminals B and C, connect the terminals A and B), and the lamp 1 is turned off.
Press button B of the transmitter: The relay 2 is activated (connect the terminals B and C, disconnect the terminals A and B), and the lamp 2 is turned on.
Press button B again: The relay 2 is deactivated (disconnect the terminals B and C, connect the terminals A and B), and the lamp 2 is turned off.

3) Setting Interlocking mode: Disconnect Jumper-1 and Jumper-2.
Mode Interlocking (working with transmitter C-3): Press -> On; Press another button -> Off.
Press button C: The relay 1 is activated (connect the terminals B and C, disconnect the terminals A and B), and the lamp 1 is turned on. The relay 2 is deactivated (disconnect the terminals B and C, connect the terminals A and B), and the lamp 2 is turned off.
Press button B: The relay 2 is activated (connect the terminals B and C, disconnect the terminals A and B), and the lamp 2 is turned on. The relay 1 is deactivated (disconnect the terminals B and C, connect the terminals A and B), and the lamp 1 is turned off.
Press button A: The relay 1 & 2 are deactivated (disconnect B and C, connect A and B), and two lamps are turned off.

4) Setting Momentary (Channel 1) + Self-locking (Channel 2) mode: Connect Jumper-1 and Jumper-2.

How to pair the transmitter to the receiver:
Notice: We have paired the transmitter to the receiver before leaving the factory.
1) Press the learning button of receiver for 1- 2 seconds; signal LED on the receiver is on. The receiver enters into status of LEARNING.
2) Press any one button on transmitter. If signal LED flashes quickly 15 times and turns off, it means learning is successful.
3) When receiver is in the status of LEARNING, press again the learning button, signal LED turns off, learning process will be discontinued.
4) The receiver can learn several transmitters with different codes.

How to delete all transmitters codes stored in the receiver:
Notice: We have paired the transmitter to the receiver, if you don’t want the receiver to work with the transmitter, you can delete all transmitters codes stored in the receiver.
Operation: Press and hold the learning button of receiver until signal LED flashes slowly; release the button, LED keeps slow flash. That means all stored codes have been deleted successfully.
