great product. controlling lights on my boat

Web searches (on the subject) may result in many instructions of the controller which may not apply to the product you bought. They are interesting anyway.The machine-translated manual of GV-RK04S-12 may not completely satisfy many readers, but the content of it is valid. Interesting find!You find the jumper underneath the learning button, right? You count the pins from left to right: 1-2-3. Jumping 1 o 2 you'd have the loads (lights) moving from one to another (remember the ring counter); No jumps at all (3 pins are free: momentary mode; Jump 2 to 3: toggle mode. That's it! Read the whole manual? May be you don't have to. JUST PLAY WITH THE JUMPERS. (If for the moment you don't need the jumper, save it.)Please stick to the attached manual (or just play with the jumper!) Fun guarranted.

It's a neat idea and the range is amazing. I could open my garage door from 1/4 mile away (country roads)But it has a fatal flaw. 5 or 6 times a week, this would trigger the garage door all on it's own. That makes it dangerous and unusable.

Works great. Has awesome range. I just wish the remote had a cover, or an on off switch.

I built a camper in 2019 and have been upgrading it. I wanted to add more light so added 8 more puck lights in the process of installing a cedar ceiling. They are on an overall remote control linked in with 6 lights in the kitchen area. That gives me overall control over the on/off and dimmer function.I wanted to be able to control the on/off function of the 8 new lights individually in zones of 2 lights. The little remote circuit allowed me to do that. Each 2 light string was connected in series into a central distribution box. I just broke the positive line to each string and inserted the relay on the new board. That worked giving me on/off control for each leg individually. Worked like a charm. I would buy again in a heartbeat.I especially liked the wire terminals. I was able to crank down on the wires quite hard. Nothing stripped. I know those wires are not coming out any time soon.All soldering seemed quite good and programming was very easy. This was a great buy. I wish I could say the same for many other electronic circuits I have bought.

Follow the website instructions. The {A} relay output is the one closest to the dc input. The {D} relay is on the end closest to the LED. Test the operation with a continuity meter first. If you connect wiring the way it shows with the enclosed instructions you will blow the fuse on that circuit. (or cause a small fire)

I bought two of these about two months ago. One was installed in my buddy's barbershop as a temporary solution to switch a shopvac while his central vacuum unit for six barber chairs is being repaired. It has been used six days a week since installed and switched on and off several times per day with no issues. The remote works good as well. The receiver and shopvac are in an adjacent room and the signal has no trouble going through the wall to the other room.I used the second switch on my garage shop vac that I use for several wood working tools. It works great.I only have two negative comments. The first is they are a sort of a pain to pair the remote. Each switch took a couple tries to get them in the mode I wanted. Not that big of a deal, because you don't have to do it again unless you want to change modes. They hold the setting even if the power goes out, which leads me to my second negative... The power has gone out a couple times and the switches turn on by themselves when power is restored. I had a shopvac run for several hours in my garage one day while I was at work. Turn it off with the remote when this happens and you are back to normal until the next power interruption. I have the remote switch wired ahead of my shopvac, so to keep it from happening again I just turn off the power switch on the shopvac itself when I am done for the day.

The Term Learning Button is only a Remote Pairing button ,,, not relay learning as I expected.Here is my scenario.Button "A" - A Jog button ( momentary)Button "B" - Forward Reverse (Latching)I was under the impression from reading that I could put the jumper in the mode I wanted (Momentary) then press learn then the "A" button .... then change the jumper to Latching ... press the learn button then press "B" and I would have "Independent" functions on those buttons.That is not the case ... the jumper determines the "One" and only function all relays follow.If you need only latching or momentary etc. on "all" the relays then this will work.Mixing functions is not possible.So, because of the use of the term "Learning and Independent" instead of "Paring Button , mode jumper" I will give a rating of 3 .... Nice unit .... easy setup ... misleading terms (language problem ? )
