R Co. - Add-A-Zone Single-Wire Dual-Zone Control

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.

Features & Benefits

• Both valves connected to an Add-A-Zone are independently timed and activated from the controller for both manual and automatic operation
• The 2 valves can be assigned to separate watering schedules and programs in the controller
• Permits easy addition of an additional valve to controllers with spare stations without the need to divide out a run
  time on a single zone or activate the new valve every other watering cycle
• Makes adding a valve to correct water pressure problems easy
• Broken wires can be abandoned and worked around without loss of programming flexibility
• Fast and inexpensive to install
• The added valve can be a master valve
