Easy to program, small size, good responsiveness, good range of 15 meters through a brick wall. The black circle on the socket is a diode that lights up when underwriting the relay contact, so when it is active. Relay = no worries whatever the lamp to light diode, neon etc .. no more than 1000W Caution! So we not command a vacuum cleaner or iron! Easy programming: choose a code on the remote control by micro switches called DIP switch rated 1-5 and both ON and OFF positions, or 32 possibilities. With a small Phillips screwdriver, the hatch is opened and a socket is created the same code as the remote control switches 1 to 5. It remains 4 switches A, B, C and D. When the door switch A is The decision will be activated by the button at the top of the remote control B by one below, and so on. Nothing complicated. Advantages: If a plug lights alone because a neighbor has the same code or a wireless transmitter or temperature doorbell disrupts, just change the code 1-5. If two jacks have the same code 1-5 and the same code A, B, C or D, it can control two devices at the same time ..... or 3 or with the same button If we have another YC-2000B group with the same coding 1-5 then we have taken 4 and 2 remote controls to activate the last two places. That's what interested me! If power fails, the mechanical coding that there is no memory loss. When the power returns, it works as before and without learning I take off a star because I would have liked a push catch for manual control.
