5. Apply power to the timer.

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.
