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.
