Sprinkler System Basics The three main components of every automatic sprinkler system are the controller, station control valves and sprinklers. The controller is the brain of the system, telling the control valves when and how long to supply water to the sprinklers. The sprinklers direct and control the water applied to the lawn and plants. Each valve controls a specific group of sprinklers called a watering station.
Watering Program Basics A watering program requires three basic instructions to operate automatically: • What days to water –called watering days • When to water – called a program start time • How long to water – called station run time Watering Program Diagram Program Starts - 5:00 AM Station 1 12 6 The following example illustrates how a typical watering program could be set for the sprinkler system shown on the previous page. Example: The program start time is set for 5:00 AM.
Watering Program Details This section covers in detail each of the three parts of a watering program – watering days, program start times and station run times. Selecting Watering Days The GreenKeeper 212 provides four options for scheduling watering days: Calendar, Interval, Odd or Even and Off. Calendar Schedule A Calendar schedule enables you to select specific days of the week to water, for example, Monday, Wednesday and Friday. This is a seven-day schedule which starts on Sunday and ends on Saturday.
Selecting Program Start Times Setting the Station Run Time 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 the program will water in numerical order, one at a time for its set run time. A station run time is the length of time the station (controlled by the valve) will water during the program watering cycle.
Planning Your Watering Schedule It is always helpful to plan your watering schedule on paper before beginning the programming steps. You will have a record of your watering schedule and station locations which can be kept with your GreenKeeper 212 after it is installed. If you have an indoor model controller, a watering schedule form is provided on page 12 for you to fill out then remove to keep with the controller. This form is duplicated on a decal located on the inside cover of the outdoor model.

Programming Before Installation The GreenKeeper 212 utilizes a 9-volt battery to retain its watering program information in the event of a main power interruption. This battery backup feature also enables your controller to be fully programmed for operation right out of the box—before installation—in the comfort of your home. Simply attach the battery and begin the programming steps.
Selecting Optional Features 24-Hour Clock Mode The GreenKeeper 212 is set to display time in the 12-hour clock mode. If you prefer to use a 24-hour clock mode (military time), select this option by removing the 12/24 Hour Selector Jumper (5). To store the jumper, install it on one pin as shown. See Figure 3. Figure 3 BATTERY 15-Second Run Delay The 15-second run delay feature is useful for sprinkler systems utilizing a pump or master valve.
Resetting the Controller Memory The GreenKeeper 212 program memory can be reset to the permanent program values or cleared completely at any time without removing power. Figure 4 2 3 Resetting the permanent program erases all user input and replaces it with the permanent program values. Clearing the program memory sets all program values to Off (i.e., no active days, program start times or station run times).

Controller Operation The GreenKeeper 212 controller has three modes of operation: Automatic, Manual and Off. In the Automatic mode the controller tracks the time and day and operates the automatic watering schedules. The Manual mode enables the watering programs to be started and controlled manually at any time. The Off mode shuts off all watering activity and prevents any zones from operating automatically or manually.
Manual Operation Manual operation enables the automatic watering programs or selected stations assigned to the program to be started manually. During operation, temporary changes can be made to increase or decrease the station run time, step through the station sequence and pause or stop watering using the “Watering Control Features” described on page 32. Upon completion of the manual watering operation, the controller will return to the Automatic mode.
Watering Control Features The following watering control features enable you to further control the watering program during operation. All watering control features apply to watering programs started manually and automatically. To Pause Watering To Cancel Watering Press the +/ON and –/OFF buttons at the same time two times. • All watering operations will be canceled and the controller will return to the automatic mode.
Turning Off the GreenKeeper 212 Flashing When the control dial is turned to the OFF position, the controller immediately shuts off any watering operation currently in progress. Leaving the control dial in the OFF position will prevent all automatic and manual watering operations. The controller will continue to track the current time and day of the week. PM 1 3 MO 2 For extended shutdown of the sprinkler system leave the control dial in the OFF position. The word OFF will be displayed for 8 minutes.
Using the Season Adjust Feature Changes in season and temperature generally require a change in station run time to maintain a healthy landscape and conserve water. The season adjust feature enables you to change the run time of all zones assigned to a program, simultaneously up or down, in 10% increments – with just the press of a button. Adjustments can be reduced to 10% or increased to 200% of the programmed run time of each station.
Service and Specifications Adding a Station Module 1. Turn the control dial to the OFF position.
