ET Manager Series - Installation and Operation Manual 19
2. Output Method
To accommodate almost any type of sprinkler con-
troller, the ET Manager has four Output Methods:
Standard
• Enable: This is the most common setting. A
sprinkler controller output is enabled to allow
watering only when needed.
Advanced
• Enable A then B: This output operates the
same as the “Enable” method with one signifi-
cant difference. There may be instances when
watering needs to be spread over two days.
The Enable A then B mode allows watering on
only one valve group per day, then alternates to
the other valve group on the next available day.
• ET and Rain Pulse: Advanced ET-based con-
trollers can recognize ET and Rain pulse
inputs.
• ET Pulse with Weather Interrupt: ET Pulse
with Weather Interrupt is similar to ET and
Rain Pulse with a second output acting as a
sensor interrupt to prevent watering if any one
of the three Weather Interrupt conditions
occurs; rain, freezing conditions or high wind.
If not using Enable, review chapter 8, Advanced Output
Methods.

3. Site Specific Settings
Site specific settings are programmed to meet the
needs of your landscape and sprinkler system. From
Settings in the Main Menu access:
• Irrigation Control
• Weather Interrupt
Note: Refer to Appendix II for default settings, or to
chapter 6, Determining Programmable Settings to
establish site specific ET Manager settings.
Irrigation Control
Main Menu Settings Irrigation Control
Irrigation control settings are based on site specific
conditions. Plant type, soil type, sprinkler system capa-
bilities, and available watering periods affect these set-
tings:
• Irrigation Amount & Adjustments
• Water Window
• Available Watering Days
• Advanced Settings
Irrigation Amount and Adjustment
Main Menu Settings Irrigation Control
Irrigation Amount and Adj
The Irrigation Amount represents how many inches (or
mm) of water is applied to your landscape for Valve
Group A and Valve Group B during each watering cycle.
This amount of water evaporates from your landscape
before the ET Manager will allow watering to occur.
The Landscape Adjustment Percentage is used to adjust
for site-specific landscape needs for Valve Group A and
Valve Group B. The Landscape Adjustment Percentage
is applied to the calculated ET, and effects the current
Moisture Levels for Valve Groups A and B.
