Install help, hunter pro c with sensor

I understand the zones, need help with the sensor setup and valve.

What kind of sensor are you using? From the looks of it, you were running the system in bypass mode, meaning that at least rain sensor was not being used. I believe that other types of sensors available to Hunter from products like solar sync are not compatible with Rachio. This should not be a big loss since Rachio is designed to gather that data over the internet connection so you could stop using the sensor all together without major drawbacks.

As far as the valve, I’m assuming you are asking about the master valve, not one of the zone valves. Your master valve appears to be connected to the bottom zone terminal via a thin red wire. The terminal is labeled “P/MV” on your controller. You will need to connect it to the M terminal of the Rachio, it is on the middle top terminal block next to the sensors.

Its an irritol wireless setup. Additional picture…

Here is the page outlining how to set it up.

Keep in mind that rachio does not actually measure rain via these sensors, and they only influence normal operation while outdoor sensor is wet. Be sure to setup your rachio account to use a good local weather station.



The additional red white and blue wires that go to the power. What are those for? (There are seperate wires that bring the power to the unit)

Looks like they are for hunter remote

Your new rachio will use WiFi for that, so it looks like you can disregard them.
