PRO1248 is available in 12, 18, 24, 36 & 48 station conﬁgurations. Designed

to cover a wide range of applications from residential and commercial turf, to light agriculture, and professional nursery.

This controller has a possible 8 separate programs with up to 64 starts per day. The controller has a 7 day watering schedule with individual day selection per program or a 365 calendar for odd/even day watering or selectable interval watering schedules from every day to every 15th day. Individual stations can be allocated to one or all programs and can have a run time of 1 minute to 12 hours 59 minutes or 25 hours if the water budget is set to 200%.

Holman has always been concerned with sustainable water usage. The controller has many water saving features that can be used to maintain the highest standard of plant quality with the least amount of water consumption. The integrated budget facility allows global changes of run times without affecting programmed run times. This allows for decreasing total water consumption on days of minimal evaporation.

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.

 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

Each press will move to the next program number. This is handy for quick reviewing of previously entered information without losing your place in the programming cycle.

SET AUTOMATIC PROGRAM

 Set the automatic program for each group of stations (valves) by completing the

following three steps:

1. Set start times

This sets the time when the watering schedule is to commence.

Note: For each start time, all the stations (valves) selected for the program will

come on in sequential order. If two start times are set, the stations (valves) will come on twice.

2. Set Watering Days

These are the selected days when the automatic system will be active.

3. Set Station Run Times

This sets the watering duration required for each station (valve).

Page 7

PROGRAMMING EXAMPLE

A typical example of a 12 station system is outlined below as a guide to assist you when planning your watering schedule. In this example only 5 of the possible 8 programs are used, the lawn areas are using gear drive sprinklers. The vegetable garden is using drip and the ﬂower beds are being watered with micro sprays.

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. Advance to the selected station by pressing

as many

times as required, and adjust the run time with

and

. The controller will start running the selected station and the run time will decrement in the display. If there is an active pump set for this station, the pump icon will ﬂash once the button has been pressed, indicating that the pump/master is running. As soon as the single station run time has elapsed, the unit will revert back to automatic mode. This means that if you forget to turn the dial back to the “Run” position, the controller will still run its automatic starts, as scheduled. To turn the station off, change the position of the main dial, to “OFF”.

HINT: If you wish to alter the default value from 10 mins to some other value and set this as the new default time. Turn the dial to “Run Single Station” press the button. Then alter the run time using the

buttons. Once the new

default time is set press the

button again, and the new default will now always

appear when you select a “manual single station”.

Run a System Test

To manually run a system test turn the dial to the “System Test or Run Single Station” position, press

and

together.

The display will show:

The default run time for a single station is 2 minutes. If you wish to alter the run time for this start only, use

the

and

buttons. Once the correct run time has been entered, turn the

station on and make it run by pressing the

button.

Page 16

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.

To skip to the next station press the

button. To go back a station press the

button. To stop the system test, change the position of the main dial, to “OFF”.

HINT: If you wish to alter the default value from 2 mins to some other value and set this as the new default time, press the

and

together followed by

button. Then alter the run time using the

buttons. Once the new

default time is set press the

button again, and the new default will now always

appear when you select a “manual system test”.

Run a Program

To manually run a complete program or to stack multiple programs to run, rotate the dial to “Run Program”. The word “OFF” will be ﬂashing.

The display will show:

To enable program 1 to start press the

button. The icon “OFF” will change to “ON”. This program has now been enabled so that it can be run. To make program 1 run, press the

button.

NOTE: So long as there are run times in program 1 then program 1 will start and water the stations associated with it.

Page 17

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.

Enable program 1 by pressing the

button. To select the next program press

the

button, the program number will increment to program 2.

Enable program 2 to run by pressing the

button.

NOTE: to disable a program number, press the

button.

Once both programs have been enabled, they can be run by pressing the

button. The controller will now run all programs that have been enabled starting with the highest numbered program. So in this case, program 2 would run and when it has completed its cycle, program 1 would start and run its cycle.

This method can be used to enable any, or all of the available programs on the controller.

NOTE: When running programs in manual mode the “Budget %” will alter the running times of each individual station.

MANUAL OPERATIONS

Page 18

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” them in sequential order. All programmed start times will be watered from the highest number ﬁrst.

Automatic Backup

This product is ﬁtted with permanent memory. This allows the controller to hold all stowed values even in the absence of power sources, which means that programmed information will never be lost. Fitting the 9 volt block battery will keep the real time clock running during power outages. However, if the battery is not ﬁtted the real time clock is backed up every 10 minutes to the non volatile memory. This means that when the power returns the clock will be restored to its last known value.

It is recommended that a battery is ﬁtted and it is changed every 12 months.

A low battery icon will light when the battery has a week left to run. When this occurs, replace the battery as soon as possible so that the clock is maintained correctly during power failures.

Page 19

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”.

Turn the dial to “Set Auxiliaries” to enable individual

stations to be set rain sensor “ON” or “OFF”.

The display will show:

If the station is turned “ON” this means that the sensor will control it, should it rain. The default mode is for all stations to be rain sensor “ON”. Should you have a station (valve) that always needs to be watered, e.g. an enclosed green house or plants that are under cover, then the rain sensor can be turned “OFF” for these particular stations. This way when the sensor is wet they will still water. To select a station to turn “OFF”. Press the

button, the word “ON” will now be

ﬂashing, use the

button to change to “OFF”.

TIP: To turn the station back “ON” press the

button. To advance to the next

station use the

button and the station number will increment. Do this operation

for all stations (valves) on the controller that need to be altered.

HINT: To disable the rain sensor and allow all stations to water regardless of the setting, move the slide switch marked Rain/Sensor to the “OFF” position. The reactivate it slide the switch to the “ON” position.

Page 20

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. Turn the dial to the “Set Auxiliaries” position. Then press the

button. The rain delay value will now be ﬂashing.

The display will show:

Press the

button to alter the rain delay time in increments of 12 hours at a time. A maximum delay of 240 hours or 10 days can be set.

Stop All Watering

To stop all watering cycles during winter, turn the dial to the “OFF” position.

The display will show “ALL OFF”:

This means that all automatic schedules will not come on, but the programmed information is still retained in the memory and the clock still keeps track of time even though it is no longer being displayed.

To reactivate watering, turn the dial to the “Auto Run” position.

Page 21

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” position. Press the

button.

The display will show:

This means that the run times are set to 100%, i.e. if station 1 is set to 10 minutes then it will run for 10 minutes. Should however the value change to say 50% then instead of running for 10 minutes station 1 would now run for 50% of 10 minutes, i.e. 5 minutes.

Conversely should the budget value be altered to show 200% then instead of running 10 minutes on station 1, it would run for 20 minutes. The budget calculation is applied to all stations and all run times that are active.

To increase the budget percentage press the

, to decrease the budget

percentage press the

. The percentage value will increment or decrement in

multiples of 10%. The maximum value is 200% and the minimum value is 10%.

To return to the clock display press the

button

Should the budget value no longer be 100% then it will be shown in the clock display, e.g. if we set the budget to 200%

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. However if there is a dual water supply or some of the stations may be used to run garden lights, the pump master valve input may need to be turned off for selected stations. Pumps can be assigned to be activated by a program or alternatively by individual stations, not both. The standard default is that all programs are set to pump “ON”.

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 that 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 and bores, where draw down can occur or cavitation of centrical pumps is a problem.

WARNING: This option is used to make pumps work against closed heads. This can lead to pump failure, pipe splitting and in some cases, explosion of pressure vessels. Understand how to use this option and consult a hydraulic engineer regarding the use of this option in your system before implementing it.

To access the pressure build option, turn the dial to the “Set Auxiliaries” position, press the

button until the following display appears.

SPECIAL FUNCTIONS

Page 25

The display will show:

Press the

or the

buttons to increment or

build time too.

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 the

buttons to increment or decrement the delay time

seconds.

This value can be anything from OFF to 99 secs.

Water Hammer Saver

The water hammer system is used to stop fast valve closures causing water hammer and damaging pumps and pipe work.

This facility allows the overlap of valves for a speciﬁed time between valve changes. For example the system is changing from valve one to valve two.

1. Valve one is open 4. When time elapses valve one closes

2. Valve two opens 5. Valve two now runs for its speciﬁed run time.

3. Time delay counts down

seconds. This value can be anything from OFF to 99 secs.

SPECIAL FUNCTIONS

Page 26

LOOPING PROGRAM FOR PRO 1248

The looping routing allows for the highest program in the unit to be used for looping. The looping program can be set in Hours/Minutes or in Minutes/Seconds. A delay time can be programmed between loops, and the number of loops can also be programmed. The looping program can run in two modes, it can run concurrently with other stations or it can run exclusively with other stations. When in concurrent mode the looping station runs at the same time as an overlapping program. When in the exclusive mode the looping program will take control of the system and run any other programs only when it goes into the “delay between loops mode”. Be careful when using this mode. Large looping cycles and small delay times can mean that there is not enough time per day to run a complete cycle. The controller will then stack the following day’s program starts.

Before setting your looping routine it is necessary to program a start time, set watering days and station run times in program 8. This program records the looping program.

NOTE: The run time at this point can only be set in Hours/Minutes, and this will automatically convert to Minutes/Seconds if this option is selected when setting up the looping routine in the “Auxiliaries” position.

To set the looping routine turn the dial to the “Set Auxiliaries” position. Press the button six times until the following appears:

NOTE: If the “OFF” icon is not ﬂashing then there is no run time set for the program and it will not let you proceed.

Set the run times before setting the looping program.

To enable the looping program press the button, the display will show “ON”.

To disable the looping program press the button, the display will show “OFF”.

There are two looping functions; standard and continuous (frost control).

Standard looping:

Standard looping is generally used for greenhouse and nursery applications, and is also suitable for new turf installations.

Continuous looping: (needs to be factory set)

This system is used for frost control using a temperature probe. Connect the probe

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.

LOOPING PROGRAM

Once the looping program is enabled it is possible to gain access to its menu by pressing the button. The No of loops will be ﬂashing.

The display will show: Select from 1 to 99 loops. “C” continuous loop appears after 99, and should only be used if a temperature probe has been connected.

To alter the number of loops that will occur use the button to increment the number of loops or the button to decrement the number of loops. If the letter “C” appears in the looping No’s digit, this means that the looping can now be activated via the sensor input, breaking the contact between “S” and the “Com” terminals will cause the looping program to stop till the contacts close again. This system is used for frost control using a temperature probe.

To alter the delay time between loops press the button and the hours of the delay time will ﬂash. Press the button to increment the delay hours or the

button to decrement the delay hours.

To alter the delay between loops press the button, the minutes of the delay time will now be ﬂashing. Use the or the to increment or decrement the delay

minutes. Press the button again and the “SINGLE STATION” icon will ﬂash. This means that the looping will take control of the programs and only allow them to run in the delay time between loops. If you would prefer to run in “MULTI STATION” (concurrent) mode press the button. To return to exclusive mode press the

button.

Press the button and the “MIN” icon will ﬂash. This means that the Station run times will run Hours and Minutes. To run in Minutes and Seconds press the

button and the icon will show “SECS” ﬂashing. For example if station had 12 hours 59 minutes programmed as it’s run time in the looping program, then in Min/Sec mode this would be converted to 12 minutes 59 seconds. To change the setting to Hours/Mins press the button. To set it back to Mins/Secs press the

button. This completes the steps required to set the looping program. To exit the menu either turn the dial or press the button.

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.

INBUILT MODEL: The inbuilt controller unit is an outdoor model and can be exposed to light rain as it is weather proof.

Fasten the controller using the hooks positioned externally on the top left and right. Additional holes are positioned internally under the terminal cover.

Electrical Hook-up

WARNING:

1. All electrical work must be carried out in accordance with these instructions

following all applicable local, state and federal codes pertaining to the country of installation. Failure to do so will void the controller’s warranty.

2. Disconnect mains power supply before any maintenance work to the controller or

valves is undertaken.

3. Do not attempt to wire any high voltage items yourself, i.e. pumps and pump

contactors or hard wiring the controller power supply to the mains. This is the ﬁeld of a licensed electrician. Serious injury or death could result from improper hook up. If in doubt consult your regulatory body as to what is required.

Field Wiring Connections

PREPARATION

1. Prepare wire for hook-up by cutting the wires to the correct length and stripping

approximately 0.25 inches (6.0mm) of insulation from the end to be connected to the controller.

2. Ensure terminal block screws are loosened sufﬁciently to permit easy access for

wire ends. Insert stripped wire ends into the clamp aperture and tighten screws. Do not over tighten as this may damage the terminal block.

Page 29

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. air conditioners, pool pumps, refrigerators). Lighting circuits are suitable as power sources.

This inbuilt transformer model, is suitable for outdoor installation as the housing is weatherproof and UV stabilized. However it is recommended that the unit be installed in an area which is not exposed directly to the weather.

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. (Both ends of the terminal block)

INSTALLATION INSTRUCTIONS

Pump Start Relay Connection (Water supply by pump system)

This controller does not provide mains 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. This in effect, inhibits the chances of the pump ever running against a closed head.

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. 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.

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. As a good rule of thumb select your cable as follows:

0–50m cable dia 0.5mm 50–100m cable dia 1.0 mm 100–200m cable dia 1.5mm 200–400m cable dia 2.0mm

When you are using multiple valves per station the common wire needs to be much larger as it needs to carry more current. In these circumstances choose a common cable 1 or two sizes larger than required. When making connections in the ﬁeld, only ever use gel ﬁlled or greased ﬁlled connectors. Most ﬁeld failures occur due to poor connections. The better the connection here, and the better the waterproof seal the longer the system will perform without trouble.

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.

The system test routine sequences through all available stations on the controller. In the above example this would mean stations 8 through to 18 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.

ELECTRICAL CHARACTERISTICS

Electrical Outputs

POWER SUPPLY Mains supply: This unit runs off a 240 volt 50 hertz single phase outlet.

The controller draws 30 watt at 240 VAC.

The internal transformer reduces the 240 VAC to an extra low voltage supply of 24 VAC. The internal transformer is fully compliant with AS/NZS 61558-2-6 and has been independently tested and judged to comply.

ELECTRICAL POWER SUPPLY: Input 24 volts 50/60Hz ELECTRICAL OUTPUTS: Maximum of 1.0 amp

To solenoid valves:

24 vac 50/60Hz 0.75 amps max

Note: up to 3 valves per station on the inbuilt model

To the master valve/pump start:

24 vac 0.25 amps max

Note: Transformer and fuse capacity must be compatible with output

requirements

OVERLOAD PROTECTION: Standard 20mm M-205 1 amp fast blow glass fuse.

POWER FAILURE: The controller has permanent memory so the data is always backed up even with the absence of all power, however to maintain the real time clock as current, a 9 volt block battery should be installed. This will keep the clock time for extended periods without mains power.

WIRING: The output circuits should be installed and protected in accordance with wiring code for your location.
