4. System Check
Now that your ET Manager is installed and pro-
grammed, ensure successful operation by following the
guidelines outlined in this chapter to verify that instal-
lation and programming is correct. To ensure the sys-
tem check is completed properly, Refer to Appendix
VIII: ET Manager Installation Checklist.
System Check
Verify these settings or tests after installation and pro-
gramming are complete:
• Control Mode
• Weather Signal Test
• Valve Control Test
• Water Window Settings
• Initial Moisture Level
Control Mode
Main Menu Control Mode
There are three operating or Control Modes plus a tem-
porary Override mode. The three Control Modes are:
• Automatic (normal operating mode)
• Historical ET
• Disabled
Automatic
Automatic control is the standard mode setting. In
this mode all automatic functions are active and your
ET Manager will operate as programmed. It will utilize
the incoming weather signal to manage sprinkler con-
trol.
To set the ET Manager in Automatic mode, navigate the
menus to the Control Mode screen.
A bullet
• will be in front of the mode the ET Manager
is currently set in. If the cursor
is not in front of
“Control Mode”, use
Œ or Õ to move the location of
the cursor to Control Mode. Press
À to move the
cursor location to the operating mode. Use
Œ or Õ to
position the cursor in front of “Automatic,” and press
à to move the cursor back to Control Mode. The
•
will be at “Automatic.”
Historical ET
When in Historical ET Control Mode, the ET Manager
uses programmed daily ET averages for each month of
the year to manage sprinkler control. In the Historical
ET mode information from the weather signal is
ignored. If an on-site rain gauge is installed with your
ET Manager, the rain data recorded will adjust sprinkler
control.
The Historical ET Control Mode is provided for 3 rea-
sons:
1. In the event that the weather signal is tem-
porarily not available, the ET Manager will
operate based on Historical ET information as
default backup.
2. There may be situations when you need a spe-
cific watering schedule. For example a seeded
lawn may need daily watering. If needed, you
can set the Control Mode to Historical ET and
program the desired daily ET value.
3. Some locations may not currently receive a
weather signal. An ET Manager can still be
used to control sprinkler schedules based on
Historical ET. Under these conditions an on-
site rain gauge will provide improved real-time
control of watering schedules.
Disabled
The ET Manager can be disabled. All automatic func-
tions are suspended. The weather signal will continue
to be received and logged, ET will be calculated, but all
outputs are disabled and the Valve Group A and B
Indicator Lights will go off. The ET Manager will not
interrupt the sprinkler controller and the sprinkler sys-
tem will operate as if the ET Manager was not there.
Note: If your ET Manager is set back to Automatic
