installing the Sprinkler controller in
Five easy Steps
Your new controller has been designed for easy, con-
venient installation. Simply slide the controller off the
docking port, screw the docking port onto a wall in an
appropriate location, insert the various connections into
the sockets at the bottom of the docking port, and slide the
controller back on. finally, install the sleeve for the remote
control device. follow these 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 controller off the docking port. (See Figure 5)
• 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 controller 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 6)
• 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 controllers
together with one transformer.
4. connect Valve Wires to controller, Pump
Start and Master Valve Terminals
a. Wire the Electric valves
noTE: If the distance between the sprinkler controller and
valves is under 700’ (210 m), use Hydro-rain
®
sprinkler
wire or 20 gauge (aWG) plastic jacketed thermostat wire
to connect the sprinkler controller 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.
IMPorTanT: all wires should be joined together using wire
nuts, solder and/or vinyl tape. for additional protection to
waterproof connections, a Hydro-rain
®
grease cap can be
used.
• Next, connect the remaining wire from each valve to a
separate colored sprinkler wire.
• To avoid electrical hazards, only one valve should be
connected to each station.
IMPorTanT: The wire can be buried in the ground. How-
ever, for greater protection, wires can be pulled through
conduit and buried underground. Be careful to avoid bury-
ing the wires in locations where they could be damaged by
future digging or trenching. (See figure 7)
