in THE MAIN WALL
Having problem with zone 1 relay chatter when priority jumper is removed (for priority). Zone 2 works fine regardless. Zone 1 works fine with jumper in place (no priority). Not the relay, short in connected load or t-stat circuit. Replaced control, same thing. Does anybody know what is going on with these things??

    My guess is that you have the incomming line voltage wrong.
    White goes to "N" Neutral and Black goes to "H" Hot. My guess it that you have power/black to "P".
