If you have had a power off failiure - it is very likely that your system was hit by a power surge. When this happens, it is likely that the circuit board that controls the relays to turn on/off have now malfunctioned. Unfortunately there is no way to fix this as it is all internal on the circuit board.

If you want to test this theory, all you need to do is by pass the controller taking the 24v wiring from the board and connecting it directly to one of your valve wires. If that zone turnes on, then the unit is bad and will need to be replaced.
