Description: Input Voltage: 12 V Receiver sensitivity: > 97 dBm Transmitting distance:> 100 m ( open space) Decoding mode: MCU software decoding Remote storage: 20 Support remote type: EV1527 learning code Working mode: Momentary, toggle, latching time delay (5s,10s,15s ) Output terminal: NO, NC, COM Dimension of PCB:35 x 30 x 18 mm (L, W, H) Remote control battery: 2 x 3 V CR2016 button batteries Note: Maximum input power is 12 V Remote programming Working mode: 1. Inching mode: press the remote control the relay will connect, and then release the remote control to disconnect the relay 2. Self-locking mode: press the remote control the relay will connect, and then press the remote control again to disconnect the relay 3. Interlock mode: press the remote control key A to connect the relay, and press the remote control key B to disconnect the relay. 4. Delay mode: press the remote control the relay will connect, release the remote control, and start timing. After 5S, 10S, and 15S (3 gears), the relay will be automatically closed. Learning Methods: 1. Inching learning method: Press the code pairing button on the control panel once, and the LED indicator will flash once. After the LED indicator is lit, press the button you need to pair on the remote control, the LED indicator on the control panel will flash 3 times which means the pairing succeed. 2. Self-locking learning method: Press the code pairing button on the control panel twice, and the LED indicator will flash twice. After the LED indicator is lit, press the button you need to pair on the remote control, the LED indicator on the control panel will flash 3 times which means the pairing succeed. 3. Mutual lock learning method: Press the code pairing button on the control panel three times, and the LED indicator will flash three times. After the LED indicator is lit, press the button you need to pair on the remote control, the LED indicator on the control panel will flash 3 times which means the pairing succeed. 4. 5S delay learning method: Press the code pairing button on the control panel four times, and the LED indicator will flash four times. After the LED indicator is lit, press the button you need to pair on the remote control, the LED indicator on the control panel will flash 3 times which means the pairing succeed. 5. 10S delay learning method: Press the code pairing button on the control panel five times, and the LED indicator will flash five times. After the LED indicator is lit, press the button you need to pair on the remote control, the LED indicator on the control panel will flash 3 times which means the pairing succeed. 6. 15S delay learning method: Press the code pairing button on the control panel six times, and the LED indicator will flash six times. After the LED indicator is lit, press the button you need to pair on the remote control, the LED indicator on the control panel will flash 3 times which means the pairing succeed. Cleaning method: Press the code pairing button on the control panel eight times, then it will automatically clear all the learned remote controls. After clearing, the remote control previously learned can no longer be used. Package includes: 1xReceiver module 1xRemote Control (with battery)
