watering.
Water source not supplying water.
Verify there is no disruption to the main water line and
that all other water supply lines are open and functioning
properly.
Wiring is loose or not properly
connected.
Check that field wiring and master valve or pump start
relay wiring is securely connected at the controller and in
the field.
Field wires are corroded or
damaged.
Check field wiring for damage and replace if necessary.

installed, the system does not irrigate but programs show
as remaining active.

do not start.
Connected rain sensor may be
activated.
Set Rain Sensor to BYPASS to ignore the rain sensor. If
watering resumes, the sensor is operating properly and
no further correction is needed.
Connected rain sensor may not be
operating properly.
Let the rain sensor dry out, or disconnect it from the
controller terminal strip and replace it with a jumper wire
connecting the two SENS terminals, or set to Bypass.
If no rain sensor is connected, the
jumper wire connecting the two
SENS terminals on the terminal
strip may be missing or damaged.
Move dial position to Sensor Bypass and set to Bypass.
It just rained and
the alarm light is not
illuminated, why?
This is normal operation. The
ESP-Me does not consider the
interruption of irrigation due to
rainfall an alarm condition.
This is normal operation.
