The controller repeats itself or continu-
ously 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 19.
There is no display. Check AC power wiring. Correct any errors.
The display reads “ERR”. Electrical noise is entering the system. Check the SmartPort
®
wiring harness. 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 wire to the pump start
or 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 water tight.
The display reads a station number and
ERR, such as “2 ERR”.
There has been a fault with the wire leading
to that station.
Check the station wire for continuity. Replace
or repair shorted wire. Check that all wire
connections are good and water tight.
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.
