An enhanced version of the powerful and flexible TWC Flowmaster line, this TWC-NV takes advantage of significant improvements in modern electronics technology.  The TWC-NV requires only 2 wires to control up 200 valves, up to 7 miles away.  This remarkable feat is accomplished by a uniquely-addressed decoder to the 2-wire path; the decoder is also connected to the valve.

The TWC-NV is available in four capacities – 50, 100, 150, 200 decoders.  Upgrades can easily be performed via software keycodes.
