The controller repeats itself or
continuously waters, even when it
should not be on (cycling repeatedly). Too many start times (user error). Only one start time per active program
is required. Refer to “Setting Program
Start Times” on page 21.
There is no display. Check AC power wiring. Correct any errors.
The display reads “SP ERR”. Electrical noise is entering the system. Check the SmartPort ® wiring harness.
Verify that the red wire is attached to the
AC1 terminal, the white wire to the AC2
terminal and the blue wire to the REM
terminal. If the wires were extended then
they will need to be replaced with shielded
cable. Contact your local distributor for
information on shielded cable.
The display reads “P ERR”. There is a fault in the pump start,
master valve, or the wiring for the
pump start/master valve. Check the master valve or pump start
wire for continuity. Replace or repair
the shorted wire. Check that all wire
connections are good and watertight.
The display reads a station number and
ERR, such as “2 ERR”. There is a fault in the station solenoid,
or the station wiring. Check the station wire for continuity.
Replace or repair shorted wire. Check
that all wire connections are good
and watertight.
The display reads “NO AC”. There is no AC power present
(the controller is not receiving power). Check to see if the transformer is
properly installed.
