RF remote

I purchased this UNIT to use in the MOMENTARY mode (to energize the relay only while the remote button is held down--similar to momentarily pushing a button) and it was a little tricky (took me about 4 times) reading the instructions to be able to reprogram it. It comes shipped in the mode that most people would probably want (to toggle a light or appliance ON and then to push the button again to turn the light or appliance OFF.Since my garage door opener receiver board went bad, I just needed something to electrically push the wired garage door button on the wall for me. This little unit (once reprogrammed) works fantastic!What I liked:- The receiver did exactly what I wanted it to do (momentarily close the contacts on the garage door pushbutton switch on the wall).-The unit even worked great with a 9V battery (used that to make sure I knew how to program it) but I then connected an inexpensive 120VAC to 12VDC adapter I got from Amazon for $4 to power the unit- I was going to uncoil the antenna wire inside the receiver (for a greater distance) but before doing that, I walked 120+ feet away from the garage door and pushed the button and it worked great!What could have been a little better:- The instructions are somewhat unclear when you are reprogramming the unit for MOMENTARY mode, but after I read it numerous times and memorized what I had to do, since you only have a short time to continue programming, everything worked OK. The trick was holding the button on the transmitter down (on the last step) UNTIL you hear the relay click.OVERALL: I like the unit and it saved me from buying a door opener receiver circuit card ($100) or a new garage door opener ($150+). If your garage door opener works by pushing the wired button on the wall, but doesn't work remotely due to a bad internal circuit card, this is a great inexpensive fix.

Very small, but works good. Doesn't lag on like other remotes do. Doesn't hesitate when you push either button either. Would buy again.

This is a 2 channel remote meaning you can control two different projects at the same time. I only use 1 channel to turn on/off my Renogy DC to DC charger for my motorhome when on the road. It is about 35' from the drivers seat to the battery control box and it has no issue with the range. The instruction are a bit confusing (or I am dumb as a box of rocks), but did figure it out. DOWNSIDE - The container is a bit small and wiring can get pinched when making wiring connections so I mounted the guts in a larger plastic container in the battery bay.Why did I use the remote vs directly connecting the DC to DC charger to the ACC...would have been difficult to do so, so using the remove bypassed the ACC. I also didn't want to run a separate a separate power on/off line to the DC to DC charger from the front of the coach (all DC to DC chargers require a 12vdc supply to power on/off), and this was the perfect solution.

It’s been operating for last 6 months and I’m happy with it. The beauty of remote control is that you can program garage home link button to enable / disable exhaust valve actuator. For newer model Jaguar F Type, the factory programmed the valves to open at 3500 rpm or higher. With this modification you can have the valves open in entire rpm spectrum.

Unlike the one I returned, this RF relay came with a thorough, well written instruction pamphlet with plenty of clear illustrations. I simply followed directions to switch modes to “momentary” and it worked perfectly first time. It came with two transmitters pre-paired to the receiver. Changing modes from toggle (default) to momentary clears the transmitters as well but pairing them is a breeze... only one thing to note: pairing a transmitter is done by pressing one the program button on the receiver then a button the transmitter and finally the other button on the transmitter. Just remember that the first button you press on the transmitter gets paired to channel 1 and the second to channel 2. Make sure you program both transmitters in the same sequence so they operate the same way. I left the cover off because mine is installed in a closed box and controls 12V DC only (but it’s made for 120V AC also). The connectors from the relays out is too close to the edge. It would difficult to wire it and close the case (see photos).

I've asked multiple times, but the vendor has not replied.This 2 channel device comes with 2 remotes. I can get both remotes to pair with the relay circuits, but I cannot get both remotes to work the same way. The A button on one remote toggles the A relay and the B button toggles the B relay. On the other remote, the A button toggles the B relay and the B button toggles the A relay.There needs to be a response from the seller as well as clear instructions on how to fix this in order for this 2 remote product work as expected.

too little information about how it should be connected, how much powerful the power supply should be.i connected according to a schematic picture linear actuator with black and red wires, and .... it did noteven move the motor.

Works exactly as it’s described. This little thing could have about a million uses. For me it solved a problem of two different brand garage door openers with failing remotes. One is 30yr old no name and the other is a fairly new Wayne Dalton opener, that for some reason has security on par with a nuclear middle silo. This little guy programmed easily and now opens and closes both doors with a surprisingly long range. Quite a bargain if you ask me. It does require a little basic electrical knowledge based on your intended use, but nothing to be worried about.
