Firmware Version
To check your KD2’s rmware version, place the control
dial to
Special Functions position and press the
button as needed until the rmware version is displayed
(V001 or later).
Automatic Circuit Breaker
The KD2 controller features an electronic circuit breaker
which automatically detects an overload condition on a
station terminal during operation and turns o the station
before controller damage can occur. The KD2 advances to
the next programmed station in sequence to continue the
watering cycle.
After the program watering cycle has nished, FUSE and
the number of the skipped station(s) will be displayed in
alternating sequence with the current time of day. If all of
the station numbers and FUSE are displayed, the master
valve is malfunctioning. Pressing any button will remove
the warning display.
Important: The most common cause of an overload
condition is a short circuit in the valve wiring or a
malfunctioning valve solenoid. The cause of the overload
condition should be corrected before continuing to operate
the controller.
