Draft 3: Recommendations

The final draft, submitted to the EPA, and summary review for the second draft are below.
The subject of add-on devices and how many controllers with which they would need to be tested arose at the SWAT meeting held at the Irrigation Show, November 4, 2008. SWAT was directed by the attendees to develop recommendations for testing add-on devices that can work with new or existing systems.
Important: This is not part of nor will it be part of the protocols for climatologically- or soil moisture sensor-based controllers. It is a suggested position for EPA consideration.
