times will not change, but the actual amount of time that is watered will be adjusted per your Season Adjust setting. Automatically
adjust watering of any Zone(s) by percentages by using left Up/Down arrows to adjust from -90° to+100°.

Troubleshooting
Problem Possible Cause Possible Solution
Automatic and Manual cycles do not
begin watering.
Water source not supplying water. Make sure the main water line and all supply lines are open and
operating properly.
Wires not properly connected. Make sure all field wires and master valve/pump start relay wiring is
connected properly.
Wires loose or cut; corroded connections. Check field wiring for broken, cut, or “skinned” wires and replace if
necessary. Check all wire connections and replace with watertight
splice connectors as needed.
Dial not set to AUTO RUN. Make sure the dial is on AUTO RUN—not any other dial position.
If you have a Rain Sensor, it may be activated. You can either wait until the Rain Sensor dries out, or disconnect
the Rain Sensor from the yellow terminals on the timer and replace it
with a wire connecting the two yellow terminals.
If you do not have a Rain Sensor, the wire
connecting the two yellow Rain Sensor terminals
may be damaged or missing.
Connect the two yellow Rain Sensor terminals in the timer’s terminal
bay with a short length of 14 to 18 gauge wire.
An electrical surge may have damaged the
timer’s electronics.
Press the reset button under the wiring cover. If there is no
permanent damage, the timer should resume normal operation.
You will need to input the correct time and date, but your watering
schedule should remain intact.
