Section 5: Using the Optional
Rain-Freeze Sensor
An optional rain-freeze sensor can be purchased separately to
prevent programmed watering for a specified period of time
after rain falls or during periods when temperatures fall below
a specified temperature. The sensor has settings for RAIN,
and RAIN/FREEZE. Please refer to the manual that accompanies
the rain-freeze sensor for installation and programming instruc-
tions.
NOTE: The rain-freeze sensor will function only when the selection
dial on the timer is turned to AUTO.

Installing the Sprinkler Timer
in Five Easy Steps
1. Select a Location
Select a location with the following criteria:
• Near an electrical outlet. (Avoid using an outlet controlled
by a switch.)
• In a dry, indoor location, where operating temperatures
are not below 32° or above 122° Fahrenheit (below 0
degrees or above 50 degrees Celsius).
• Not in direct sunlight.
• Accessible to sprinkler wires from valves.

2. Mount the Docking Port
• Slide the timer off the docking port. (See Figure 3)
• Using the mounting template (included), mark the two
screw locations on the wall, then drill holes at the marks
for No. 8 screws. Use the expanding anchors in plaster or
masonry if necessary.
• Place the docking port against the wall, aligning the two
holes in the docking port with the two drilled holes.
• Secure the docking port to the wall by screwing a No. 8
screw (included) through each of the two holes.
• Do not slide the timer back onto the docking port yet.
3. Connect the Transformer
• Find the two sockets at the bottom of the docking port
labeled "24VAC." (See Figure 4)
• Insuring the transformer is not plugged in; insert one of

the two power leads from the transformer into each
terminal socket using the phillips screwdriver to depress
the terminal button (this allows for wire insertion or
removal).
• Plug in the transformer.
WARNING: Do not link two or more sprinkler timers together with
one transformer.
4. Connect Valve Wires to Timer, Pump Start and Master
Valve Sockets
A. Wire the Electric Valves
NOTE: If the distance between the sprinkler timer and valves
is under 700' (210 m), use Orbit sprinkler wire or 20 gauge
®
(AWG) plastic jacketed thermostat wire to connect the sprinkler
timer to the valves. If the distance is over 700' (210 m), use 16
gauge (AWG) wire.
• Taking the sprinkler wire, strip 1/2" (12 mm) of the
plastic insulation off the end of each individual wire.
• Connect one wire from each valve (it doesn't matter
which wire) to a single "common" sprinkler wire. This
is usually white. (See Figure 5)
IMPORTANT: All wires should be joined together using wire
nuts, solder and/or vinyl tape. For additional protection to
waterproof connections, an Orbit grease cap can be used.

• Next, connect the remaining wire from each valve to a
separate colored sprinkler wire.
