Installation and Setup Procedures
Install Receiver
• Position the receiver next to the timer (on the side opposite the timer's
hinged cover).
• The receiver can be installed indoors using the mounting tape provided.
For outdoor installation, attach the receiver using the two stainless steel
screws provided.
• When installed outdoors, the receiver cover should remain closed when
access is not required.
1. Drive the top mounting screw into the wall, leaving
about 1/8" from flush.
2. Place the receiver on the screw using the key-
hole slot.
3. Install and tighten the lower mounting screw.
4. Route the connection cable through the bottom of
the timer, into the wire connection area.
Connect Receiver to Timer
Note:
If the timer is equipped with sensor terminals, continue at Step 1 below.
If the timer is not equipped with sensor terminals, continue at Step 1a. Refer
to your timer's user guide for specific information regarding sensor installation
and Sensor control switch operation.
Note:
When the receiver is connected to the timer's sensor terminals, Rain Hold
will be indicated when the Precision Soil Sensor is actively restricting irrigation.
The Precision Soil Sensor does not replace or function as a Rain Sensor.
Caution: Ensure the timer's power source is disconnected prior to con-
necting the receiver wires.
Timer Equipped with Sensor Terminals
Setup for Timer With Sensor
1 . Locate the Sensor connec-
tion terminals. If the timer
has (or requires) a jumper
wire on the Sensor termi-
nals connect the receiver
for Normally Closed (NC)
operation. If a jumper wire
is not required, connect
the receiver for Normally
Open (NO) operation.

2 . For a Normally Closed Sensor:
Remove the jumper wire, and connect the Brown and White wires to
the Sensor terminals (in either position). The Yellow wire is not used.
For a Normally Open Sensor:
Connect the Yellow and White wires to the sensor terminals (in either
position). The Brown wire is not used.
3 . Continue to Step 4 below.
Setup for Timer Without Sensor
1a . Remove the wire(s) connected
to the field Common terminal
(labeled COM or C).
2a . Using a twist-on wire connec-
tor, attach the Brown wire to
the wire(s) removed from the
Common terminal. The Yellow
wire is not used.
3a . Attach the White wire to the
Common (COM) terminal.
Common Setup (continued)
4 . Attach the Red wires to the timer's 24 VAC power terminals.
Caution: The receiver requires a source of 24 VAC continuous power
for operation. Severe damage will result if wired directly to 110/120 VAC.
5 . Apply power to the timer.
Note:
When the receiver is initially powered
up, the green LED will light, and the display will
show two bars with alternating Signal
Battery
symbols.
Adjust Watering Program
Review the timer's automatic watering program and adjust as necessary to
provide the following watering schedule:
• Set watering to run every day of the week – with the exception of restricted
Red
watering days.
Red
• Set a run time duration for each zone that will provide thorough watering
– without causing pooling or runoff.
• Ensure an automatic watering cycle will run within 16 hours after initial
installation of the Precision Soil Sensor.
