Using the Diagnostic Circuit Breaker
The ESP-MC is equipped with a circuit overload protection system. This system
causes the controller to skip over a station that has an electrical short circuit, rather
than blow a fuse which would shut down the entire system.
When the controller tries to start a station that has a short circuit, the electronic circuit
breaker senses the short circuit and skips that station. The controller skips to the next
station, but flashes the skipped station number and FAULT in the display.
Once you have corrected the problem, push the FAULT RESET button to clear the
flashing fault indicator.
Note:
The diagnostic circuit breaker allows detection on all valves, including the mas-
ter valve.

Scheduling Chart
Before you begin programming, it is a good idea to chart your watering schedule, tak-
ing into account the schedule for all stations and how often you want to repeat the
schedule. A sample schedule appears below.
