Page 6: Programming Instructions
ProGraMMInG InstructIons IntroductIon This controller has been designed with 6 separate programs to allow different landscape areas to have their own individual watering schedules. A program is a method of grouping stations (valves) with similar watering requirements to water on the same days. These stations will water in sequential order and on the days selected. Group the stations (valves) which are watering similar landscape areas together. Examples: Turf, flower beds, gardens. These different groups may require individual watering schedules, or programs. Plan your watering schedule completing the planner supplied at the back of this book. Set the current time and correct day of the week. If odd or even day watering is going to be used, make sure the current year, month and day of the month is correct. hint: To select a different program use the button marked . -

Page 20: Special Functions
sPecIal FunctIons PuMP on/oFF selectIon In most systems the water supply will be from a well or from the mains. This controller will turn on either a pump (well supply) or master valve (mains supply) each time an automatic or manual start occurs. Normally the pump or master valve is activated for all stations. However if there is a dual water supply or some of the stations may be used to run garden lights, the pump master valve may need to be turned off for selected stations. Pumps can be assigned to be activated by a program or alternatively by individual stations. The standard default is that all programs are set to pump “ON”. To set pumps per program: Turn the dial to “Set Auxiliaries”. Press the button once. The DiSplay Will ShoW: This means we are in the pump per program menu for Pump No 1 (master valve). Press the button to enter this menu option. Program 1 will now be flashing. The DiSplay Will ShoW: This means that the pump will turn on when program 1 is running. To select a different program number press the or the button. To turn a pump ON or OFF for a particular program press the button so that “ON” is now flashing. Press the button to turn the pump ON or press the button to turn the pump OFF for that particular number. -
Page 21: Pressure Build
sPecIal FunctIons Station No 1 will now be flashing and it will be OFF. The DiSplay Will ShoW: This means the pump will not turn on when station No 1 running. To turn the pump ON or OFF for a particular station press the button so that “OFF” is now flashing. Press the button to turn the pump ON or press the button to turn the pump OFF for that particular station number. Complete this sequence for all station No’s by pressing and adjust “ON” or “OFF” with the or buttons. Pressure buIld The pressure build system is used to allow the recovery of water supplies and to speed up slow valve changes within a system. Basically what happens is, as the controller changes from one valve to another, a system delay is inserted between valves. In essence, during this delay period, the pump is working against a closed head. The advantage of this is in systems where the valves are slow to change, it is possible to speed them up by inserting a delay period and pressurizing the main line. This system can also be used on wells, where draw down can occur or cavitation of centrical pumps is a problem. warning: This option is used to make pumps work against a closed heads. This can lead to pump failure, pipe splitting and in some cases, explosion of pressure vessels. -
Page 22: Water Hammer Saver
sPecIal FunctIons nOtE: Each program can have its own pressure build time programmed. To alter the pressure build time press the button. The delay time is set to “OFF” and will now flash for the selected program number. Use the or buttons to increase or decrease the delay time seconds. This value can be anything from OFF to 99 seconds. water haMMer saver The water hammer saver is used to stop fast valve closures causing water hammer and damaging pumps and pipe work.

Page 23: Installation Instructions
InstallatIon InstructIons MountInG the controller Install the controller near a 120VAC / 240VAC (International) outlet. Preferably located in a house, garage or exterior electrical outlet. For ease of operation, eye level placement is recommended. Ideally, your controller location should not be exposed to rain or areas prone to flooding or heavy water. The controller can be installed indoors or outdoors and can be exposed to light rain as it is weather tight. Fasten the controller using the key hole slot positioned externally on the top center and the additional holes positioned internally under the terminal cover. electrIcal hooK-uP Warning: . All electrical work must be carried out in accordance with these instructions following all applicable local, state and federal codes. Failure to do so will void the controller’s warranty. . Disconnect power supply before any maintenance work to the controller or valves is undertaken. . Do not attempt to wire any high voltage items yourself, i.e. pumps and pump contactors or hard wiring the controller power supply. this should be done by a licensed electrician. Serious injury or death could result from improper hook up. -

Page 25: Pump Start Relay Connection
InstallatIon InstructIons PuMP start relay connectIon (water suPPly by PuMP systeM) This controller does not provide power to drive a pump. A pump must be driven via an external relay and contactor setup as detailed below. The controller provides a low voltage signal that actuates the relay which in turn enables the contactor and finally the pump. hint: Although the controller has permanent memory and thus a default program will not cause erroneous valve actuation as in some controllers, it is still good practice when using a system where the water supply comes from a pump to connect unused stations on the unit back to the last used station. -
Page 26: Master Valve Installation
InstallatIon InstructIons Master valve InstallatIon The purpose of the master valve is to shut off the water supply to the irrigation system when there is a faulty valve or none of the stations are operating correctly. It’s used like a back-up valve or fail safe device and is installed at the start of the irrigation system where it is connected to the water supply line. -
Page 27: Pump Protection (System Test)
InstallatIon InstructIons PuMP ProtectIon (systeM test) In some circumstances not all operational stations might be hooked up. For example, if the controller was capable of running 9 stations but there were only 7 field wires and solenoid valves available for connection. This situation can pose a risk to a pump when the system test routine for the controller is initiated. The system test routine sequences through all available stations on the controller. In the above example this would mean stations 8 through 9 would become active and would cause the pump to operate against a closed head. This could possibly cause permanent pump, pipe and pressure vessel damage. It is mandatory if the system test routine is going to be used, that all unused, spare stations, should be linked together and then looped to the last working station with a valve on it. Using the above example, the connector block should be wired as per the diagram below. Link any unused stations to the last active station. -
