Why this kit?

The value Pack retrofit kit is based on the Value Series (VS) family of spa controls designed using Balboa’s patented M7 temperature and flow sensing technology. VS systems have a plastic enclosure that eliminates corrosion while suppressing intruding water. The connectors are built onto the circuit board, which minimizes wires and simplifies service problems. The Value Pack is meant to be installed by a spa professional who can work with a kit known for being reliable and easy to install and service.
