Selecting Program Start Times
A program start time is the time of day you select to
begin an automatic program watering cycle.
It is important to remember that a program only
requires one start time to operate automatically.
When a program starts, each station assigned to a pro-
gram will water in numerical order, one at a time for its
set run time.
Sometimes it is necessary to run a watering program
more than one time per day. For example, when growing
a new lawn. The GreenKeeper 212 enables each pro-
gram to have up to four separate start times per day.
Program start times are numbered 1 through 4. These
numbers are shown at the top left of the display next to
the start time symbol when the control dial is in the
PROGRAM START TIME position and indicate how
many start times are currently set for the program.
This illustration shows how
a program start time is
displayed. In this example,
program A has one start
time (start time number 1)
set for 5:00
AM.
Setting The Station Run Time
A station run time is the length of time the station (con-
trolled by the valve) will water during the program water-
ing cycle. The run time for each station can be set from
Off (no run time) to 4 hours, in one-minute increments.
A station is assigned to a program when it is given a run
time. If the run time for a station is turned Off in a pro-
gram, it will not operate during the program watering
cycle. This is how the GreenKeeper 212 enables you to
assign stations to different programs.
All stations assigned to the program are shown on the
lower portion of the display when the control dial is in the
STATION TIMES position.
This illustration shows how
a station run time is dis-
played for a program. In this
example, zones 1–6 are
assigned to program A.
Station 1 has a 10-minute
run time and station 2 is set
to run for 25 minutes.
The station run time being
displayed is identified by the
flashing station number.
