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 OR B)
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.

To Remove
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.
Replacing the Battery
Your 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 transformer must
be connected to an AC line voltage source.
