PROBLEM CAUSES SOLUTIONS
The controller does not start
automatically.
Possible programming error. Check to make sure start time is entered
correctly (note AM/PM setting as well).
Check to make sure watering day is active.
Rain sensor will not shut off system.
Incorrect sensor type wired directly into sen-
sor circuit. (Jumper installed)
Make sure sensor is microswitch type such
as Mini-Clik
®
.
The controller recognizes 48 stations
all the time.
Microprocessor requires reset. Make sure AC power is connected. Reset
controller using method described on
page 34.
The controller does not respond to all
the stations. Example, the controller
has 24 stations but the display will
only go to 16 stations.
Controller does not recognize modules. Turn off the power to the controller and re-
move the battery. Check all module connec
-
tions to the controller. Power the controller
back up. The microprocessor will recognize
all modules.
The controller is only recognizing eight
stations when multiple modules are
installed and/or there are not enough
start times for all stations.
The dial is in the START TIMES position and
not the STATION RUN TIMES position (see
page 26).
Be sure dial is in correct position. Total
number of stations can be easily checked
by placing dial in SET STATION RUN TIMES
position and pressing the back arrow.
Controller has display but will not
activate zone valves.
Primary power to controller incorrectly
wired. Controller receiving voltage too low
for valve operation.
Check and correct 110 or 220 volt
connection. 110 volt may be incorrectly
wired as 220 volt.
