Watering Issues
Problem
Possible Cause
Possible Solution
Automatic and
Manual cycles
do not begin
watering.
Water source not supplying
water.
Verify the main water line and all supply lines are open and
operating properly.
Wires not properly connected.
Verify 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 position.
Verify the dial is in the AUTO position.
If a Rain Sensor is installed, it
may be activated.
Wait until the Rain Sensor dries out, or disconnect the Rain
Sensor from the yellow terminals on the Controller and replace
it with a jumper wire connecting the two yellow terminals.
If no Rain Sensor is installed, the
jumper wire connecting the two
yellow Rain Sensor terminals
may be damaged or missing.
Connect the two yellow Rain Sensor terminals in the
controller’s terminal bay with a short length of 14 to 18 gauge
jumper wire.
An electrical surge may have
damaged the Controller’s
electronics.
Press the Reset button located under the wiring bay cover. If
there is no permanent damage, the controller should resume
normal operation. Current time and date will need to be
entered, but the watering schedule should remain intact.
