Install 

your 

new 

timer 

by 

following 

these 

six steps:

STEP 1: SELECT THE LOCATION

A. Select an indoor location near a conventional 120 volt dual electrical

outlet.

CAUTION: The timer should not be placed where it is exposed
to a temperature exceeding 55” Centigrade (130” Fahrenheit)
or on a circuit controlled by a switch. Malfunctions may result.

B. If the timer is adistancefrom the outlet, replace the supplied

 cord 

with

a similar electrical cord (available at hardware and electrical supply
stores).

STEP 2: MOUNT THE TIMER

A. Screw in a No. 8 

screw 

at 

eye level, leaving the screw head extended 1/8"

B. Slip the keyhole opening on the back 

of 

the timer over the screw head.

C. Open the timer and install two screws through the holes in the wiring

compartment at the bottom of the timer.

NOTE: To install the timer on a plaster or masonry wall, use
plastic or lead shields to secure screws

STEP 3: WIRE THE VALVES

8

Place valve wiring underground where possible. (Under 800 feet, use
18 gauge, plastic jacketed, thermostat control wire; over 800 feet, use
14 gauge wire. This wire is available from your dealer in 2,3,4,  5,6,7,

and 8 color coded wires).

Run one common wire to all valves.

Solder all splices, or join them with wire nuts and seal with vinyl
cement or other waterproof cement.

IMPORTANT: The power transformer is protected by an elec-

tronic circuit breaker. Do not connect a combination of valves

requiring an inrush current of more than 1 AMP at 24 VAC. (Two

valves maximum).

STEP 4: CONNECT THE VALVE WIRES TO TIMER

A. Bring valve wires up through the hole on the bottom of the timer.

B. Connect the wire from valve number 1 to the terminal screw on the

timer marked 

“1

 “,

 valve number 2 to terminal “2”, and so forth.

NOTE: The terminal designation is marked on the inside of the
wiring cover.

C. Connect the common wire to the terminal marked “COMM”.  (Fig. 1)

D. If using a water pump or master valve, refer to page 1 1 for instructions

and diagrams. (Fig. 2).

STEP 5: CONNECT THE TRANSFORMER

A. Connect the power leads from the timer to the plug-in transformer.

B. Attach one lead to each terminal screw on transformer. Be sure

terminals on cord do not touch.

C. Plug in transformer.

CAUTION: Use with supplied transformer ONLY!

STEP 6: CONNECT THE BATTERY

Battery will keep program in memory during temporary power failure.

A. Connect a 9 volt alkaline battery (not supplied) to the battery

connector in the wiring compartment of the timer box.

B. Place the battery in the wiring compartment.

C. Replace wiring compartment cover.

D. Replace battery at least once a year. More often if frequent power

failures occur.

CAUTION: DO NOT ALLOW THE BATTERY CONNECTOR TO TOUCH THE
TIMER’S TERMINAL STRIP (DIRECTLY ABOVE THE WIRING COMPART-

MENT).ALSO, DO NOT CONNECT OR DlSCONNECT VALVE WlRES WHILE

ANY ZONES ARE IN OPERATION.
NOTE: 
Check local codes to be sure wiring and installation will meet all requirements.
