The Weather Reach Water
Management System
Your ET Manager receives a wireless weather signal from
the Weather Reach Water Management System. The
Weather Reach Water Management System (Figure 3)
automates commercial and residential sprinkler sched-
ules using real-time weather conditions. A Weather
Reach Signal Provider (WRSP) retrieves information
from local weather stations. The information is broad-
cast as a weather signal via a paging radio frequency to
your ET Manager. The weather signal contains the most
recent weather conditions including:
• Solar Energy
• Temperature
• Wind
• Humidity
• Rainfall
The ET Manager uses this data to compute water loss
and control how often your sprinkler controller waters
your landscape.

Weather Reach Signal Provider
Your Weather Reach Signal Provider (WRSP) retrieves
weather information from local weather stations and
sends the weather signal to your ET Manager. Your
WRSP communicates with your ET Manager using
Signal Provider Codes (see chapter 4, Programming)
programmed into your ET Manager. The Signal
Provider Codes are available from
www.rainbird.com/etmanager, where you can down-
load and print an information sheet with specific infor-
mation regarding your local WRSP.
