The Hunter ET System allows an irrigation program to be created automatically, based on local climate conditions. The program is then operated
via a compatible irrigation controller’s Program A (except ACC controllers, see page 14) and runs automatically, on water days and at start times
set by the system operator. Compatible controllers are Hunter Models SRC/SRC
Plus
, Pro-C, ICC, and ACC with SmartPort
®
technology.
ET System uses sensors to determine the local “evapotranspiration” (ET) rate of turf and plants. This is a formula which calculates how much wa-
ter the plants have lost, or consumed, due to local atmospheric conditions. Each ET System can be customized by station (or “zone”) for specific
plant, soil, and sprinkler types.
The result is a new, water-efficient irrigation program every water day, based on local weather conditions.
Once installed, the ET-controlled zones are programmed from the ET Module, rather than the controller itself. The ET Module will display the new
program data for the climate-based irrigation.
The ET System allows manual station starts from the controller, and will also permit connection of an ICR or SRR remote control receiver.
This product is intended for turf and landscaping applications only, not intended for agricultural or scientific use.
Use the ET System Worksheet. One is included with each ET System, and this can also be downloaded free of charge from the Hunter Industries
web site (www.hunterindustries.com at the ET System product page). The ET System Worksheet will help you organize and record your station
settings. This will also help to determine and track any adjustments you may make to the watering settings. If you need Technical Support, the
Hunter technician will also need this information.
