So I’m in the process of disconnecting my existing controller (Toro model with a date code of 1992) and I see something odd. It looks like zone 6 isn’t connected to the controller… But there is an extra wire capped off. I assume there was a reason for this. I don’t know where the capped off wire goes to, but could I have a zone that is currently not being utilized? Worst case, what breaks if I wire it in to see what happens?
Zone 6 isn’t connected, but 1-5 and 7-11 are. Is there a reason for this?
