Two Valves on Only One Wire:
Let Add-A-Zone Solve Your Irrigation Problems

Work around broken zone wires. Add a new zone without adding new wiring. Add-A-Zone is the proven way to independently control two zone valves with only one pair of field wires.

Unlike other "switching" units, the Add-A-Zone behaves just like the valves are fully independent. A patented unit installed at the controller allows use of two separate zones, while sending the signal through only one field wire.

Exclusive features:

  • Both valves connected to Add-A-Zone are independently timed and controlled for both automatic and manual operation.
  • The two valves can be set to separate watering schedules and programs in the controller.
  • Unlike other switching units, no "watering every other cycle". System works the way the you expect.
  • No disruption of the landscape to repair common problems.

Solve these problems:

  • Divide existing zones stations with a new valve to correct pressure problems. Permits the addition of an additional valve to systems that have an open station on the controller.
  • Work around broken field wires and maintain full system functionality.
  • The added valve can be a master valve.
