Example: To manually water on station 3 for five

minutes, press the [MANUAL] button then press the

[   ] buttons until you see station 3; using the [+/–]

buttons, set duration to five minutes; press [ENTER].

Note: After the [MANUAL] button has been pushed, if a selection

is not made within 5 seconds all stations and programs will

begin watering using the programmed RUN TIMES. If no RUN

TIMES have been set, nothing will happen and the display will

return to the time of day.

Connecting a Rain Sensor

• Connect the rain sensor wires to the wiring terminal

ports (yellow in color) labeled “Sensor”

Note: Refer to your rain sensor manual for specific wiring

instructions.

• Place the sensor on/off switch to the “on” position to

begin operation (see figure 6)

Rain Sensor Bypass

This sprinkler timer is equipped with a sensor override “on/

off” switch. This switch is for use during maintenance and

repairs, so the sprinkler timer can be operated even if the

rain sensor is in active mode.

Important: If the rain sensor switch is in the “on” position and

no sensor is connected, the sprinkler timer will not operate.

To resume sprinkler timer operation place the switch in the

off position

TIMER

Pump Start & Master Valve

This sprinkler timer allows a master valve or pump start

relay to operate whenever a station is on.

Note: If you are activating a pump from this timer, you must

purchase a Pump Start Relay. From the pump start relay (or

master valve); connect one wire to the “Pump” terminal and the

other wire to the “Common” terminal.

Replacing the Battery

Timer requires a CR2032 Lithium battery

• The battery will maintain your program in case of an AC

power loss

• Battery should last approximately one year

• Open by sliding the battery tray out to the right

• Insert one CR2032 battery into the compartment with

the + side up

• Slide back into place.

A weak or missing battery can cause the time, date, and

program to be erased after a power failure. If this happens,

you will need to install a fully charged battery and reprogram

the timer.

Tip: Replace battery every year, to avoid loss of programming

Note: A battery alone will not operate the valves in your

sprinkling system. The sprinkler timer has a built-in transformer

that must be connected to an AC line voltage source.

TERM DEFINITION

START TIME The time the program begins watering the ﬁrst programmed station.

VALVE

Supplies water to a speciﬁc station or area. The opening and closing of the valve is

accomplished through electrical current supplied by the sprinkler timer.

MASTER VALVE

Typically located at the main water source. Turns on and off water for the entire irrigation

system when not in use.

MULTIPLE

START TIMES

A controller feature that allows a program to be operated multiple times on the same

watering day.

OVERLAPPING PROGRAMS When a “Start Time” is set for a program before the previous program has completed.

PROGRAM

(A, B, OR C)

Individual programs as set by the user. Each program operates independently. If one

program overlaps the other the programs will be “stacked.” After the ﬁrst program

ﬁnishes the next program will begin.

RAIN DELAY

A feature that postpones the running of a scheduled watering program for a speciﬁc

duration.

SOLENOID

The electrical part on an irrigation valve that opens and closes the valve.

SPRINKLER TIMER

A device which instructs the station valves to operate.

STATION

A grouping of sprinklers operated by a single valve which is controlled by the timer.

WATERING BUDGETING

Adjusts your overall watering program as a percentage of total watering duration.
