VALVE OPERATION DURING A POWER FAILURE
During a power failure, all the data will be saved and restored once the line power is restored. The data can be
saved for many years with no loss. The electronics will be inoperative and all regeneration will be delayed. The
electronics will restore all the information to the time where the power failure occurred. The valve does not record
the amount of water used during a power cut.
If the valve is in delayed metered regeneration, the reserve capacity will be set to a third of the full capacity.
