I’m having issues replacing my old (2003) Toro controller with the Rachio I just purchased. I’ve review the other posts with similar issues, but their wiring is different that what I see when I open the cover on the Toro!
See attached photos.
I took a look at the manual located at GreenKeeper w/run (andyssprinkler.com)
It appears the terminals running along the top are for zones 1-4 (left to right) with the ones on the left (top to bottom) being sensor, sensor, com, MV/pump (nothing connected), and the last two 24VAC.
For the Rachio, the common wires go to C, zones 1-4 to the same, the Rachio power supply gets plugged into the wall and also the Rachio, and that only leaves the sensor. One sensor wire would go to S1 and the other to ground or 24VAC (depending on the sensor). You can try it without the sensor attached at first and I would likely try the ground next. Well, I would probably research the sensor first to see if it needs power or not. Do you know anything about the sensor.
Thanks for your quick response!
The sensor is also circa 2003, not too worried about that. However, if you look at the left side of the photo, near age battery there is a black and a brown wire. I haven no clue what they could be for. Any ideas?
It appears the black and brown are not connected. It is possible that they are extra wires for future zones. I cannot tell where they are coming from. If they are in the same bundle of the other zone wires, that is probably what they are.
Thank you. I’ll get into it tomorrow and see what happens.
Please let us know how it goes. It appears to be straight forward to me.
Thank you for all your help, they system is installed and seems to be working fine. Thanks again.
Good work @22River!
Can someone help me w this please. My wiring looks nothing like this and I’m wanting to replace this with a Rachio
You said that your wiring looks nothing like this??? Did you mean that? If so, can you provide a picture of what yours looks like please?
@Swols93 - based on the picture you provided, the four large red wires are your zone wires and the large white wire is the common wire. Ignore the small yellow and orange wires. So put the red wires into a Rachio zone terminal (1-4) and the white wire in to the Rachio C terminal.
I’m assuming that you have four zones. There also may be a in-line rain sensor someplace.
I’d run the existing system before converting over to make sure every zone works.
I was referring to the main picture at the beginning of this thread. I posted a pic of what mine looks like w my post.
Thank you! I just had everything replaced. Now I am switching out the boxes so I can access it on my phone. Thank you for your help!
Good to know, I was thinking you were talking about the image you posted when you said it was nothing like that. Sorry about that.
It looks like as simple switch over as @DLane mentioned. The yellow & orange wires are for the Toro’s power source, but you will use Rachio’s. I do not see a sensor hooked up, but @DLane comment is probably about the wirenut on the white wires. Please let us know how the switching out goes with any questions you might have.
I appreciate it. I will hopefully try to have it all done this weekend
It worked. Very simple. Just put the red wires in 1-4 and then put the white wire in a com port. Took longer to put the box in than it did to run the wires and set it up.
It worked. Very easy to do. Four red wires went in order 1-4 and white wire went to com. Thank you again for your help.
Great, good job!
