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.
