I'm upgrading from a Pro C to a Pro HC WiFi and I can match up all the wires except for the one labeled REM in blue, what is that wire for and where does it go on the new controller? There's a place called SEN COM next to the Sensor connectors is that where it goes?

does a new wiring line need to be ran off of each manifold or do you just run one line to all of them?

Hi Matt, can you help me where would I get big wire which is installed top left side on the controller. I appreciate your help. somehow that wire got cut and i did not find it on Hunter Industries website either. Also, if you can tell me what does that wire called? Thank you very much. Waiting for your reply on this.

Hook it up. Most likely power master valve.

when my technician winterized my system he disconnected a black wire. I want to open my system myself this year and I am not sure where the black wire goes that he removed. there is currently no wire connected to the pm/v terminal. Is that where it goes?
