Usually there is a way to cycle through programming.... by repeatedly pressing program button...
Hardwired timers usually have reset button.
Some battery-operated timers can be reset by removing battery

This Rainbird site has a parts section. You may find your part.

Okay, then you answered your own question. I like it! However, did you test the wire to see if it will start a different valve and vise versa?

You should be able to put two valves on one station. If it is too much for the timer either a fuse or a "virtual fuse" on the circuit will fail. Just turn the unit OFF, separate the two valves and turn unit back ON to reset "virtual fuse".
I am an irrigation contractor and we have many timers with doubled zones.

Disconnect all zone wires and see if timer blows fuses. If not, one of the zone valves is drawing too much amperage.

The battery only holds the program in the memory. The No AC message tells you that the AC power that is supposed to operate the valves is not getting to the control unit. Someplace there is a power cord with a transformer that is taking the house current at 120V and powering the unit. Something has been disconnected or a circuit breaker is tripped. If there is an outside socket with a GFI in it, try resetting it.

All you have to do is set the program 'A B' switch to the 'A' position. The program that you have set for A will run only. B is not active.

Check programming for each zone. Be sure each zone has time on it.
