To check compatibility of a new remote with the receiver. Simply press the button on the remote, if the receiver flashes, but does not Triger the relay. The remote will be compatible, and you can start the programing process

To add a remote, press the button on receiver momentarily. The red light will come on. Then press the button on the remote that you want to program in. The red light will start flashing. After 4 flashes in will stop, and the button will be programmed in.

For the setting to take effect, the board needs to be disconnected from it’s power supply. The bellow settings will be done to the 3 headers and bridge pin on the receiver board, above the push button.

• With the header removed, the On button will switch the relay on, and the off button will in turn switch the relay off.
• With the header on Pin 1-2. Both Buttons will become momentary. And only hold the relay in place as long as they are pressed in.
• With the header on Pin 2-3. Each button will be able to switch the relay on and off individually. You will however not be able to switch the button off with the “off” button, if you switched it on with the “on” button. And vise versa.
