Page 6: Programming Instructions
PROGRAMMING INSTRUCTIONS INTRODUCTION This controller has been designed with 8 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. -

Page 15: Manual Operations
MANUAL OPERATIONS Run a Single Station The maximum run time for a station is 12 hours 59 minutes. To manually run a single station once, turn the dial to the “System Test or Run Single Station” position. The display will show: The default run time for a single station is 10 minutes. -
Page 16: Run A Program
MANUAL OPERATIONS The controller will start running all stations with the selected run time. The time will decrement in the display and will sequentially move through all stations, running them for the same set period of time. This option is designed so that it is possible to test all sprinklers and valves that make up the irrigation design. - Page 17 MANUAL OPERATIONS There may be times when it is desirable to run more than one program manually. The controller allows this to occur using its unique facility of enabling a program, before running it. For example if I wished to run Program 1 and also Program 2, the controller will manage stacking of the programs so they do not overlap.

Page 18: Stop Watering
OTHER FEATURES Stop Watering To stop an automatic or manual watering schedule, turn the dial to the “OFF” position. NOTE: For automatic watering remember to turn the dial back to the “Auto Run” position, as “OFF” will stop any future watering cycles from occurring. Stacking Start Times Should you accidentally set the same watering start time on more than one program, the controller will “stack”... -
Page 19: Rain Sensor
OTHER FEATURES Rain Sensor When installing a rain sensor, first remove the the factory fitted link between the “C” and “S” terminals shown here by the wire. Replace with the two wires from the rain sensor into these terminals, polarity NOT required. Move the rain sensor switch on the fascia to “ON”. -
Page 20: Rain Delay
OTHER FEATURES Rain Delay (Rain sensor cont...) Different rain sensors react in different ways. The most common complaint about rain sensors, is that they dry out too quickly, and allow the system to come on within hours of a rain storm. To counter this problem the controller has a “Rain Delay” setting that allows a specific delay time to elapse after the rain switch has dried out before the controller will water again. -
Page 21: Water Budgeting & Seasonal Adjustment
OTHER FEATURES Water Budgeting & Seasonal Adjustment The automatic station run times can be adjusted by percentage as the seasons change. This will save valuable water as the run times can be adjusted quickly in spring, summer, and autumn to reduce or increase water usage. Ensure the dial is in the “Auto Run”... -
Page 22: Special Functions
SPECIAL FUNCTIONS Pump ON/OFF Selection In most systems the water supply will be from a bore or from the mains. This controller will turn on either a pump (bore supply) or master valve (mains supply) input each time an automatic or manual start occurs. Normally the pump or master valve input is activated for all stations. - Page 23 “ON” or “OFF” with the buttons. Pump No.2 Selection The PRO 1248 Controller comes with a second pump / master option. To set Pump No. 2 per program: Turn the dial to “Set Auxiliaries”. Press the button 3 times.

SPECIAL FUNCTIONS to the sensor terminals “C” and “S” and slide the RAIN SENSOR switch to the “ON” position and remove the link (if fitted). The looping can now be activated via the sensor input, breaking the contact between the “C” and “S” terminals will cause the looping program to stop till the contacts close again. -
Page 28: Installation Instructions
INSTALLATION INSTRUCTIONS Mounting the Controller Install the controller near a 240 VAC outlet. Preferably located in a house, garage, or exterior electrical cubicle. 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. -
Page 29: Terminal Block Layout
INSTALLATION INSTRUCTIONS 3. A maximum of 0.75 Amps may be supplied by any output. Check the inrush current of your solenoid coils before connecting more than two valves to any one station. Power Supply Connections INBUILT TRANSFORMER It is recommended that the transformer is not connected to a 240 vac supply which is also servicing or supplying motors (i.e. -
Page 30: Pump Start Relay Connection
INSTALLATION INSTRUCTIONS Terminal Block (24,36 and 48 stations) The terminal block for 24, 36 and 48 station models is fitted to the base of the controller housing and is connected to the top panel via a ribbon cable. To get access to the terminal block remove the top panel from the controller housing by unscrewing the two screws in the lower corners of the fascia. -
Page 31: Single Phase Pump Installation
INSTALLATION INSTRUCTIONS Single Phase Pump Installation Link any unused stations to the last active station. Master Valve Installation (Water supply off mains water) 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. -
Page 32: Station Valve Installation
INSTALLATION INSTRUCTIONS Station Valve Installation Up to three 24 vac solenoid valves can be connected to each station output and wired back to the Common (COM) connector. When using long runs of cables, be aware that voltage drop can play a significant roll, especially when more than one coil is wired to a single station. -
Page 33: 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 18 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. -
