Troubleshooting
Error Detection
The Timer has a built-in error detection that senses an
electrical short circuit or overload condition on a Zone’s
output line.
In the event of an error condition, the following steps
take place regarding the error:
• The aected Zone number and “Err” alert message will
show on the display when the unit is in either AUTO or
MANUAL WATERING mode.
• All irrigation for the aected Zone is cancelled and
watering advances to the next operable Zone in the
irrigation queue.
