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?

If power is disconnected then reconnected, it will be in the off. It need to be pushed on again.

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.

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.

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.

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.

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.

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.
