System. This will wipe any moisture deficits out of memory, allowing
the ET watering to start over with normal soil.
ET System always shows the accumulated ET for the day in the dis-
play, at the Automatic position. It does not show all accumulated ET
since the last watering, only the daily total.
It may be desirable to clear the ET after maintenance operations, or
after long periods of watering inactivity.
To clear the ET and start over at 0.00 ET:
Dial at Automatic position.
Press the – (minus) button.
The Clear ET display will appear.
Press the + button to clear all ET.
To exit without clearing, turn the dial to any other position and back,
without pressing the + button.
If you choose to reset ET with the + button, the display will show ET
CLEARED. The ET will start over with a reading of 0.00.

Lithium battery: The ten-year lithium battery can be accessed from
the small sliding door on the front of the ET Module. This battery pow-
ers ONLY the real-time clock information, so that the time/date does
not need to be updated after a short-term power failure.
All program information and the station database are non-volatile, and
are not affected by this battery.
After 30 days without power, the time/date information backup will be
stopped, to save the battery. This allows the battery to survive long
shutdowns (such as during winter months). The time and date should
only require resetting after very long periods of no power, and the bat-
tery should generally not require replacement.
Solution
Check wiring. Verify that red SmartPort wire is connected to AC1, white
wire connected to AC2.
Verify that Controller has Power.
Turn off power to controller for a few seconds.
Turn power back on.
Press Reset button.
Verify ET Source (ET Setup dial position) is set to Sensor.
Wait until sensors have had enough time to accumulate data.
Turn dial to ET Setup, press and hold STA, to check individual sensor
readings.
