Replacing Orbit controller with Water Master sensor accessory

post by mbkessler on Jun 11, 2025

I just purchased a Raiche 3 12 zone controller–only using 5 zones.

My Orbit controller has a Water Master accessory which in theory turns off the system when a certain amount of rain accumulates.

This makes the wiring to the controller somewhat different.

I successfully installed the Raiche controller and it is internet functional and indicates the zone is watering, however, the water is NOT turned on.

Need help.

@mbkessler - if you have a picture of the wiring from the Orbit controller post it along with a picture of the Rachio controller wiring.

If there is a master valve in the system, check to see that the Master Valve option is set in the application.

Welcome to the community.

Thanks for your reply. Was able to connect with a Rachio rep via phone and he modified my C wire connection and it’s working properly now.
