Wireless remote control, receiver with 4 relays and 2 remote controls.
Pulse function & ON/OFF function as the choice on each button. 12-24V installation free choice 125 remote controls can be used as heart rate or OFF/TO
Remember to delete the receiver before use (button right for at least 10 sec)
A total of 500 buttons can be operated so a total of 125 remote controls can activate each of the 4 relays.
You can choose which buttons activate which output and function (pulse or on/off), in which way you can actually get, for example, a heart rate or on/off. all 4 buttons to pull the same output. It is very rare that you can get so much flexibility so simple and cheap.
If you use an adapter from any other equipment - which has no indication for the plus and minus it says + and - on the print, simply swap the wires to make the receiver work.
Remember in autumn 2015 came a new edition that requires you to hold the button down for 1 sec. before the output is activated, in addition, the relay in pulse function will only be active for a maximum of 2 sec. Even if you hold down the button.
For common age, the ON/OFF function is much more stable, as the receiver must verify the code twice before activation.
Always remember to delete the receiver completely press more than 8 sec. button on the right to delete the test program. If this is not done, the receiver can stand and respond to arbitrary remote controls.
