Add-A-Zone Now power from 2 zones on a controller can be transmitted to valves in the field through only one pair of field wires. 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.
