We are only sending out the specific #75003 Digital when ordered as part of the Total Control system, which also includes: 75001 (pool chemistry controller); 7500(4, 5, 6, or 7) acid pump and tank kit, depending on voltage of the pump and hertz of the country; 75008, optional relay kit for use when the Digital is being used to control the main circulation pump; and the manifold assembly.
This will not retrofit any previously installed Digital units. However, I am working on putting together an upgrade program but nothing is concrete yet.

I'd be very interested in finding out when and if an upgrade program becomes available.
Thanks Sean.
