No Historical ET Data
Your ET Manager uses a historical ET database as a
backup in the event weather signal service is not avail-
able. During programming, the Historical ET Database
was set based on local conditions. If this was not pro-
grammed, a “No Historical ET” message is displayed.
Action to take:
Monthly historical ET values for your
area are available from the Historical ET database
included in the ET Manager Scheduler program on the
Resource CD. Look up your city and state, and program
the monthly values into your ET Manager.

Decoder Failure
Your ET Manager uses signal decoder to receive the
weather signal. The Attention Light will come on and
“Decoder Failure” will appear if your ET Manager is
experiencing decoder problems.
Action to take:
The decoder may need to be reinitial-
ized. To do so, disconnect power from your ET
Manager, and then restore power. If the problem per-
sists, return your ET Manager for repair.
No Watering Detected
If your ET Manager has not been properly wired, or the
sprinkler controller has not been properly pro-
grammed, your ET Manager may not detect watering.
“No Watering Detected” appears on the Home screen
and the Attention Light will come on when this condi-
tion occurs.
Note:
If this condition continues, your landscape could
reach a damaging stress level. Current Moisture
Level(s) will reach a maximum dryness.
Action to Take:
1. Verify your sprinkler controller is turned on to
allow watering.
2. Verify that the current time is set correctly on
the sprinkler controller.

rectly in your ET Manager and synchronized
with your sprinkler controller. Water Window
settings should be checked to confirm that
they correspond with the start times and run
times programmed in the sprinkler controller.
4. Complete the Valve Control Test in Operation
Verification, chapter 4, to ensure Valve Groups
A and B are controlled by your ET Manager.
5. You may want to manually water affected sta-
tions.
Note:
If you have restricted the available watering
days in your sprinkler controller, you may experi-
ence a No Water Day.
Rain Tip Input Failure
Your ET Manager can use real-time rain data collected
from an optional on-site rain gauge. If you are using a
rain gauge to collect rain data and “Rain Tip Input
Failure” appears on the Home screen, your ET Manager
is indicating a problem with the Rain Tip wire terminal,
installation, or operation of the on-site rain gauge.
Action to Take:
1. Verify the on-site rain gauge is installed and
wired properly; refer to chapter 2, Installation,
Optional Rain Gauge.
2. Check the length of the rain gauge wire for cuts
or nicks, and replace damaged wire.
3. Check the rain gauge for damage.
