Review: Good range. Use it to turn well pump on/off - Mounted this in a water tight box and mounted it to the power pole at the well. Distance from house about a quarter mile. No problem operating, didn't need to extend the remote antenna. Unit antenna has a magnetic base, easy mount on top of breaker box. Switch on side of remote, " N/F" N = ON, F= OFF Weird, but whatever. As long as it works, which it does. Complaint - if your going to design something that takes 40 amps, size the terminals for that wire size. Used ring terminals to connect #10 wire to it.
Review: Must have for pressure washing setup.. - Works great. I use it to control an auto return ball valve for a downstream injector on my pressure washing system. Ive been 250 feet away from it behind a pool house and it worked every time. No more walking to remove the SH drop stick and put it in water.

## Questions & Answers

**Q: is this a latching relay? if power is disconnected then reconnected, will it still be in the on? or does the remote need to be pushed on again?**
A: If power is disconnected then reconnected,  it will be  in the off. It need to be pushed on again.

**Q: How do i use this unit with 240v when l1, l2 and n wires are required?  the unit i received has terminals for only l1 and n wires.**
A: I would connect the black and red power lines to L1 and N in, and the black and red from the motor to L1 and N output.  Connect the white from the line and the motor together.  There is no power in the white wires.  Since the unit is rated for 240v, this is the only way to make the connection.

**Q: Is thisa dpdt relay? i am wired 220v and need both legs switched, can not have a hot leg in the motor and stay code compliant.**
A: I’m using it as a switch for lighting connected to a solar array.  Both pos and neg connect to the controller however I’m not sure if its just a pass-through on one leg.

**Q: The off/on switch on the side is marked "f  n".  what does that mean, in what language?? i know that it works as an off/on switch.**
A: The only purpose of the F / N slider is to put the remote control into programming mode.  The remotes must be programmed to work with the switch.
