Verify Correct Wiring
select a sprinkler station/zone that is visible and in reach of the rain/freeze
receiver and sprinkler timer. After manually activating the station/zone, on the
sprinkler timer, press the “Manual override” button on the receiver. the top
light should indicate that the system is being overridden. If the light does not
illuminate, check the red wire connections. If the light is illuminated then the
zone watering (and the pump, if installed) should shut off. If the zone continues
to water check the white and yellow (or green) wire connections.
Verify Communication Between the Transmitter
and Receiver
Verify that the control switch, located on the bottom of the transmitter, is set on
either the “rain” or “rain/Freeze” position. next, press the manual test stem
on the transmitter until you hear a light click. While holding the test stem down
verify that the receiver “sensor Active” light is illuminated. If the light is illumi-
nated, the communication is set. If the light does not illuminate, press and hold
the “transmitter program” button for at least two seconds. once all three lights
are illuminated, press the manual test stem repeatedly until the three lights
start flashing. When the lights stop flashing press the manual test stem again,
the “sensor Active” light should illuminate. If problems persist check your wiring
or call our technical support group.

Mounting the Transmitter
Mount the rain/freeze sensor to a gutter with the provided thumb screw, or
to a flat surface, with provided screws, where it will be exposed to direct,
unobstructed rainfall (but away from sprinkler spray). the test stem must be
upright.
note: the distance that the transmitter and receiver will operate at is
approximately 200 feet line of sight. this distance may be affected by obstacles
such as walls, automobiles, metal siding, etc.
Hints for Mounting:
1. Mount the transmitter in the highest possible position where rain can fall
directly upon the rain sensor.
2. the transmitter mounting location will affect the reset rate, the amount
of time it takes the rain sensor to dry out sufficiently for the sprinkler system
to reactivate. For example, mounting the rain sensor on a very sunny, south-
eastern end of a house may cause the rain sensor to dry out sooner than
desired. similarly, mounting on the northern end of a building with constant
shade may keep the rain sensor from drying out at all. some experimentation
with the “vent ring” (described in the “Adjustments and operation” section 4)
will usually yield satisfactory results.
