CAUSES

SOLUTIONS
|
| 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 ground 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 broken wire. Check that all wire connections are good and water tight. |
| The display reads a station number and ERR, such as “2 ERR”. |
There is a ground fault in the wire leading to that station. |
Check the station wire for continuity. Replace or repair broken wire. Check that all wire connections are good and water tight. |
| The display reads “NO AC”. |
There is no AC power present to operate controller/valves. |
Check to see if the transformer is properly installed. |
| The display reads “SEN OFF”. |
The rain sensor is interrupting irrigation or not installed. |
Slide the Rain Sensor switch on front panel to the bypass position to bypass rain sensor circuit. |
| The Controller does not start automatically |
Potential user 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 sensor circuit. |
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 here. |
| 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 remove the battery. Check all module connections 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. |
User programming error. User is checking start times, not station run times. |
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. |
| The controller is continuously watering even when it should not be on/controller cycles over and over. |
Too many start times (user programming error). |
Only one start time per active program is required. Refer to "Setting Watering Start Times". |
