If the system can not adjust the clock to the exact minute, then the Odd and Even outputs are reversed. There are jumpers on the movement to correct this, but it may be easier to reverse the two output wires in the controller. | If the system can not adjust the clock to the exact minute, then the Odd and Even outputs are reversed.
