Richdel 500 PRI controller error

When a particular station is ready to turn on (7), the controller displays and blinks a FU 5 error. Do you know what that means? I am without a owners manual. Help?

boots is right.
Except its FUS, not FU5
From the manual:
Display is stuck on a
zone and “FUS” is flashing
in the display.

1. Faulty valve solenoid.
2. Shorted wire connection.
