About the Junior MAX memory
This controller is equipped with "on board" back up battery that will keep the program
memory for a few years in case power is not available. If you wish to program the
controller without connecting it to AC power, install the 9 volt alkaline battery. The 9 volt
battery will turn on the display. To turn on the programming guide light, press one of the
keys. (any key) The programming guide light will turn off after 10 seconds if no key is
pressed.
Automatic Circuit Breaker
The Junior MAX controller is equipped with an automatic circuit breaker making fuse
replacement a thing of the past. A short circuit in the field wiring or the valve solenoid
will cause the automatic circuit breaker open and stop electrical output. The “24V” will
flash and the red “AUTO” light will blink. If the fault isn’t corrected by the next start
time, the controller will initiate another watering cycle and advance through the set
stations until it encounters the station with the electrical fault. The program will again
terminate and display the blinking “24V” icon and the blinking red “AUTO” light. To
verify that there is a short circuit problem, go to the manual mode and start the station. If it
doesn’t start or turns off before the set run time, troubleshoot the field wiring and valve
solenoid.
Power failure indication
During a power failure the “24V” will start flashing, if a 9 volt battery is connected.
"24V" will stop flashing as soon as power resumes.
