no weather signal is available and the device is operat-
ing in the Historical ET Control Mode.

Programming the Sprinkler
Controller
Your sprinkler controller will need to be programmed to
work with your ET Manager. Specifically program:
• Watering Days
• Cycle Start Times
• Station Run Times
• Non-ET Based Watering Schedules
Note: Appendix VII, Sprinkler Controller Programming
Worksheet, is available as a sprinkler controller pro-
gramming aid.
Watering Days
The ET Manager controls the days of watering.
Watering days will only occur as needed, based on
weather information. The sprinkler controller should
be programmed to water every day.
Note: If you choose to program the sprinkler controller
with specific days off, then the ET Manager uses a sen-
sor to detect a no water day and will continue to allow
watering the next available day.
