Ensure all connections are secure and match the voltage requirements of your devices. Always disconnect power before performing any wiring.
Operating Modes and Programming
The DieseRC remote control switch supports three primary operating modes: Momentary, Toggle, and Latched. These modes determine how the relay behaves when a button on the remote is pressed.
Programming Instructions
- Momentary Mode (Press 1 time): Press the learning button on the receiver board once. The indicator light will illuminate. Then, press any button on the remote control. The indicator light will flash, confirming successful programming. In this mode, the relay remains active only while the remote button is held down.
- Toggle Mode (Press 2 times): Press the learning button on the receiver board twice. The indicator light will illuminate. Then, press any button on the remote control. The indicator light will flash, confirming successful programming. In this mode, pressing the remote button once turns the relay ON, and pressing it again turns it OFF.
- Latched Mode (Press 3 times): Press the learning button on the receiver board three times. The indicator light will illuminate. Then, press button 'A' on the remote control to turn Relay 1 ON. Press button 'B' to turn Relay 2 ON (and turn Relay 1 OFF). In this mode, one relay turns ON while another turns OFF, ensuring only one is active at a time.

Resetting the Receiver
To clear all programmed remote controls and reset the receiver to its default state, press the learning button on the receiver board 8 times. The indicator light will flash, confirming that all previous pairings have been cleared.
