Does this only shut the system down when it's actively raining, or will it prevent start up a day or two after a heavy rain?

The Rain Clik will actually do both. It will shut the system down if it starts raining during operation as long as it is enough water. Mine normally will not run for at least 24 hours after a good rain.

how far apart can sensor and reciever be?

Up to 800' line of sight. This varies depending on what the signal is passing through, walls, trees etc. We recommend trying to keep it within 50' of the controller.

Will the transmitter and receiver stay paired up after a power outage or do you have to manually reestablish pairing?

I have to reset from outside every time there's an outage.

Can this be installed with a Weathermatic SL 1600 controller?

If the Weathermatic SL has a "bypass" or sensor system in place, you should be able to us it. Review the owners manual for the Sensor to see if your controller wiring schematic is compatible. I used the Hunter RainClick on a Rainbird controller. Hope that helps.

Works Great & Installs Easily

This rain sensor was easy to install and works great! I took it down for the winter with the irrigation system off, but don't dread putting it back up on the gutter when we start the system up in the spring.

Wiring - consult You Tube - not the documents supplied

Device eventually set up correctly and working well. The paper instructions provided are confusing and caused me to wire it up incorrectly. Had to refer to You Tube videos - they clarified the problem quickly. Hunter user guides are not great.

Buon prodotta ma .......

Buon prodotto, funziona bene, lunga portata ma prezzo elevato e cosa che non avevo visto è che la batteria dura solo 5 anni e non è sostituibile ma bisogna cambiare il trasmettitore WR-CLIK-TR

Works out of the box (after wiring it into the irrigation unit)

Works just fine. Simply switched wires with the old unit, (no programing the receiver needed). Installed the detector on the lip of my gutter using the butterfly screw, clicked on the rain detector and voilà! Bonus points for giving me a rebate post-sale, without asking, because the price was reduced for a few days.
