Hard wire rain sensor
I tried to set it at 1/8 inch but it would NOT go down that far and I didn't want to brake it.

So, I left it on 1/4 inch. It has never turned off the sprinklers. I don't think it works.............

I do like the controller and would recommend it.

Is it compatible with HRC 990?
Thuy L on Jun 18, 2020
BEST ANSWER: I believe it is. But the short answer is, if it is NOT compatible, with this rain sensor, you can simply break the common wire and put the black wire to one side of the break and the red wire to the other. All this is is a switch that shuts the sstem off when it gets wet.
Do 2 wires go to sprinkler control? Or one?
nvarvil on Jul 7, 2019
BEST ANSWER: take your common wire out of it's slot. Attach one wire from the sensor to that wire and the other wire goes into the common slot. Place the sensor somewhere that will get the most rain.
Does this work on 24v systems? Ie Hunter SRC
