Quick Start Manual
4.  Replace the transformer compartment cover.
5.  Apply power to the timer.
  Note: The display will begin flashing 12:00 am. 
Press any button to halt flashing.
 Connecting a Rain Sensor (optional)
A rain sensor is a remote device that can be 
connected directly to your ECXTRA to automatically 
interrupt watering during rain.
A sensor control switch is provided to enable the 
sensor operation to be turned On and Off as needed
When the rain sensor detects a specified amount of 
rain, it automatically signals the ECXTRA to suspend 
all watering operations. The
“No Watering” 
symbol
will appear in the upper right corner of the 
display until the sensor automatically resets for dry 
conditions. The symbol will then disappear, and 
timer operation will resume as programmed. 
1.  Route the two sensor wires from the device 
into the timer housing through the access hole 
provided.
2.  Remove the U-shaped plastic piece from the 
Sensor terminal connectors. Connect the two 
sensor wires in any order.
3.  Set the Sensor Configuration Switch to 
NC 
(Normally Closed) or 
NO (Normally Open) 
operation as required by the type of sensor 
connected. 
  Note: Refer to the instructions provided with 
the rain sensor to determine NC or NO switch 
type and for additional installation and operating 
information.
4.  Set the Sensor Control Switch as required: 
ENB (enable) allows the rain sensor to interrupt 
watering; 
DIS (disable) bypasses the rain sensor 
input. 
IMPORTANT:
 Do not use the ENB switch 
position with the NC switch position unless 
a Normally Closed rain sensor is connected. 
Watering operation will be suspended if this 
condition occurs.
