Select the location
A. Choose an indoor location near a standard
20-volt dual electrical outlet. (250-volt outlet for 50 Hz
1
international units.)
A
CAUTION: DO NOT place the con troller
where temperatures may exceed 130"
Fahrenheit (55" Centigrade), on a circuit con-
trolled by a switch, or on the same circuit as
a high power user (refrigerator, air conditioner;
garage door opener; etc.). Malfunctions
may result.
Mount the controller
A. Install a No. 8 screw at eye level in the wall, leaving
l/8" of screw head projecting.
B. Slip the keyhole opening on the back of the controller
over the screw head.
C. Open the controller case and install two screws through
the holes in the wiring compartment at the bottom of the
controller.
NOTE: To install the controller on a plaster or
masonry wall, use plastic or lead anchors to
secure screws.
Wire the valves
A. Run valve wiring underground wherever possible. For
line runs less than 800 feet long, use 18-gauge, plastic
jacketed thermostat control wire; over 800 feet, use
14-gauge wire. Your dealer can provide this wire in 2,3,
4, 5,6,7 and 8-wire color-coded strands.
B. Connect a single common wire to one of the wires
from each valve. NOTE: It doesn't matter which of the
two valve wires you use.
C. Solder or join all splices with wire nuts; then seal
with vinyl or waterproof cement to assure a water-
resistant connection.
IMPORTANT: The power transformer is protect-
ed by an electronic circuit breaker: Do not connect
a combination of valves requiring an inrush cur-
rent of more than
amp at 24 VAC.

Connect the valve wires to controller
A. Run all valve wires up through the insulated hole in
bottom of controller.
B. Connect the wire from valve number
screw marked 1 on the controller; the wire from valve
number 2, to the terminal 2, and so on. This allows your
controller to selectively water the Zone controlled by
each valve.
NOTE: On the L80306P terminal designations
are marked on the inside of the wiring
compartment cover.
C. Connect the common wire to the terminal marked
COMM.
D. If using a water pump or master valve, refer to
page 15 for installation details.
