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

Introducing Add-A-Zone, the convenient unit that eliminates the need to add wiring when adding a zone. Use it to add additional valves to a system to correct water pressure problems. Or use it to work around faulty field wiring. Unlike other “switching” units, the Add-A-Zone behaves just like the valves are fully independent. You set the individual run times for 2 zones on the controller just like you regularly would and Add-A-Zone works “behind the scenes” to make it happen. Maximum control and flexibility that installs in minutes.

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
