Irritrol TC 12 Rain or RUN - LCD stays on Rain/OFF

I've just finished re-programming the controller for the summer watering season in New Zealand. After clipping the control module back into the unit and re-connecting the ribbon cable, I find that the LCD display remains unchanged when switching back and forth between the RUN & RAIN-OFF positions on the control module. I manually ran a Single Station and that worked O.K. I.e. the control module is operating at least one station valve.

In both the RUN & RAIN-OFF positions, the control module display is the same: OFF/RAIN/DAY/1

What have I done wrong?
