Old timer from the supply house told me I was using too many zones, I laughed it off
That guy was right, I should have just grouped the windows on the main floor into 2 big zones instead of 5 tiny ones. Now I am going back this weekend to rewire the whole thing and eat crow.
Stood there watching you laugh that off huh. Five zones for main floor windows is a lot. Bet that old timer was shaking his head the whole way back to the supply house. Gotta respect the guys who have been doing this since before zones were even a thing.
