Installing the Battery

The WVC uses a standard 9-volt alkaline battery to operate the valve and program the controller. Battery life is affected by the number of valve actuations, along with the distance the solenoids are from the controller. Under normal service conditions the battery should provide at least one full year of service.

NOTE: The WVC has non-volatile memory that retains all program information when the battery is removed or in the event the battery is drained.

To Install the Battery:

1. Unscrew the rear half of the WVC body to gain access to the battery compartment.
2. Snap the battery into the battery holder.

NOTE: The battery holder is designed so that the battery can only be inserted in one direction.

3. Make sure no water is inside the battery compartment. Make sure that the seals are in good condition. Screw the WVC body halves together to seal the compartment.
