From another post to reset: Do this.............turn it OFF. Then HOLD DOWN BOTH
the zone and mode buttons AND while you are holding them BOTH down you turn it
back on. "FF" should appear on the control and then you let up BOTH buttons and
it should work again.
we also found that we must have both front and back AC units on the same fan
setting. Low, High or Auto. One AC cannot be on low and the other on auto.
Thats ironic, I just had to install a new Due-Therm 5 button and it threw a EE code, not the E7. Anyway that is the exact procedure to reset it. Yes it turned to FF and was then functional. I was relieved knowing the next step would have been up on the roof with the sun beating down on me :E
