The wireless remotes enable this without the distraction of a crew member racing to the controller panel. They also greatly reduce maintenance time when a valve or sprinkler head is in need of repair, because the maintenance tech can immediately test the fix without hiking back to the controller to turn it on. The Hunter ROAM-XL remote control is a license-free add-on with ample wireless coverage for any sports field applica- tion. Underhill international: convert mUlti-wire to two-wire Novo, a compact two-wire converter from Underhill International, is designed to quickly transform any standard multi-wire controller to two-wire operation by using a "plug and play" feature. Controllers from companies such as Hunter, Rain Bird, Irritrol, Toro, and other popular brands, can be converted to total two-wire or hybrid two-wire/multi-wire systems when connected to Novo. The new Underhill converter is a practical solution for irri- gation installers who plan to use two-wire technology in a new installation or a system expansion because they can still use their favorite controller. Novo installs alongside the host controller and handles up to 32 two-wire zones. It is a practical solution when retrofitting existing projects when the host controller has open or unused stations. The host multi-wire controller continues to run all scheduling programs and "talks" to the new two-wire valves and decoders via the Novo converter. The technology allows Novo to use exist- ing field wire and requires grounding only at the converter. The device is especially useful in irrigation system expan- sions where it is more practical to add two-wire connections, rather than run new multi-wire to additional valves on parks or sports fields. Two-wire is also useful on projects with new exter- nal devices, such as soil moisture sensors and hydrometers. Measuring just 6.3" high x 7.33" wide x 1.78" deep, Novo features a back-lit graphical display with easy step-by-step LightTouch buttons and built-in electrical diagnostics/fault find- ing. Novo plastic wall mount cabinets and external transformers are also available. Novo has the capability of handling up to a 63-zone system if the host controller has the station capacity by using Underhill senders. Two-wire installations require less labor and materials because the 24 VAC power and address signals are sent over the same pair of wires. Novo uses standard underground irrigation wire and it is not necessary to ground field decoders. ■ ST
